PhD Studentship: Where Does COOLAIR RNA Go in Cold-Stressed Plant Cells?

PhD Studentship: Where Does COOLAIR RNA Go in Cold-Stressed Plant Cells?

This report draws on recruitment and policy information available in October 2026. The listing gives a 30 November 2026 deadline and a planned 1 October 2027 start; current availability, closing time and individual admission/award conditions require confirmation.

Quick Decision

This doctorate asks where different COOLAIR RNA isoforms are located inside plant cells, how their spatial organisation responds to winter temperatures, and how that connects to FLC regulation and flowering. The opportunity has a strong scientific fit for plant/RNA biology with quantitative imaging: the team combines prior COOLAIR structural work, direct single-RNA imaging expertise and vernalisation research. The central question is what localisation adds beyond the existing molecular-structure results, and whether isoform-specific measurements and support are ready. It is not an advertised pure-AI doctorate or a promise of a new crop variety. Official project

Research is hosted in the Ding laboratory at the John Innes Centre (JIC), with UEA registration. Yiliang Ding is the supervisor, Susan Duncan provides day-to-day co-supervision and Caroline Dean is a collaborator; these roles should not be flattened into three identically appointed supervisors. The project starts 1 October 2027, offers a four-year BBSRC NRPDTP studentship and closes 30 November 2026; the precise deadline hour was not confirmed. International applicants can compete for full awards, subject to the cohort limit and individual qualification review; a funded project listing does not mean an applicant has personally won the award, which requires selection and an individual award letter. Project, JIC registration, funding

Research Problem and Doctoral Work

Winter annual plants use prolonged cold to help time spring flowering. FLC, a floral repressor, is progressively downregulated during winter; COOLAIR is a family of alternatively processed antisense long noncoding RNAs produced at the FLC locus. Their cold responsiveness and structural diversity are established research topics, while the location of individual RNA forms within plant cells and its functional meaning remain less understood. The project therefore connects a specific spatial measurement problem to a developmental and environmental question.

The advertised work uses plant RNA imaging and advanced fluorescence microscopy in Arabidopsis. It compares how COOLAIR isoforms are organised under constant and fluctuating winter temperatures, including freezing events. Natural genetic variation and mutants affecting COOLAIR transcription and processing will be used to investigate mechanisms controlling RNA localisation and how these influence FLC regulation and flowering; whether these comparisons establish causality remains a research question. The advert cites conservation of the system in Brassica crops as a reason for wider relevance; it does not commit the student to a crop-transfer programme or promise improved yields. Work and comparisons

An important distinction is structure versus position. The 2022 COOLAIR paper resolves conformations of individual RNA isoforms and cold-dependent changes, rather than a movie of where molecules move in a cell. Conversely, a fluorescent signal's position does not itself reveal the RNA's complete fold or establish why FLC changed. A strong thesis needs a clear bridge between isoform identity, abundance, spatial distribution and biological interpretation. This is an analytical priority supported by the literature, not an extra official work package. COOLAIR structural study

Interview questions should address signal specificity and readiness, effects of cell size and developmental state, optical and image-segmentation uncertainty, and how thermal history will be related to biological replication. The day-to-day supervisor's reference-gene work is particularly relevant: quantitative imaging requires calibration, and a reference stable in one Arabidopsis tissue cannot automatically be assumed stable across every winter condition. Training in RNA and molecular biology, plant genetics, microscopy, quantitative image analysis and bioinformatics is advertised; none of that should be recast as a requirement to arrive already expert in all techniques.

School, Programme and Field Context

JIC is the specialist plant-science host, UEA is the degree-registration university, and NRPDTP supplies the BBSRC training and award framework. This is not evidence of a joint degree. The relevant field strength is specific: Ding's RNA sequence/structure programme, Duncan's plant single-molecule imaging and Dean's FLC/vernalisation and natural-variation research all address parts of the same question. Dean's profile explicitly describes a continuing collaboration with Ding. JIC registration, Ding, Duncan, Dean

UEA is joint 381st in QS 2027 overall rankings. This is not a ranking of JIC, plant RNA biology or this doctoral group. No verified project completion or placement rate was found. Ding's 2025 Royal Society Faraday Discovery Fellowship, described as a ten-year £8 million award, is evidence of competitive long-term research recognition, not a substitute for the student's own resource allocation or NRPDTP funding letter. QS, fellowship announcement

NRPDTP uses an initial training-needs analysis and personal development plan, cohort activities, masterclasses and advanced training. The standard PIPS is a three-month professional internship outside the doctoral research area, with flexible timing and support. It is not an ARIES requirement, a CASE placement of another duration or proof that this project has a first-year rotation. Confirm the timetable around plant experiments and imaging training.

Supervisors, Recent Papers and Research Resources

Ding's work integrates RNA sequence, structure, regulation and environmental responses, with experimental and computational approaches. Duncan's profile describes developing plant single-RNA imaging with Dean and Stefanie Rosa, subsequent quantitative imaging and wheat work, and RNA-localisation research before joining Ding's group in 2020. Dean contributes longstanding FLC, epigenetic and natural-variation expertise. This is a close scientific match, while meeting frequency, division of decisions and day-to-day time allocation still require a direct conversation. Ding profile, Duncan profile, Dean profile

Three original papers are especially useful for judging the opportunity:

Paper	Contribution to the project's foundation	Limit
Yang et al., Nature, 2022	Single-molecule RNA structural analysis distinguishes COOLAIR isoform conformations and their response to cold, with links to FLC expression and flowering. Ding and Dean jointly provide conceptual/supervisory leadership.	Molecular conformation is not cellular spatial localisation or live tracking. The new thesis must specify what its imaging adds.
Yang et al., Nature Communications, 2022	Combines plant transcriptome/habitat analysis with evidence that cold-responsive RNA G-quadruplex structures influence mRNA stability and cold response. Duncan and Ding are authors.	Different RNAs and readouts; it does not prove COOLAIR localisation mechanisms or universal freezing tolerance.
Duncan, Johansson and Ding, Journal of Experimental Botany, 2023	Assesses reference candidates for quantitative Arabidopsis smFISH through transcript counts, cell size and corrected intensity, giving a practical measurement foundation.	Root-meristem calibration is not automatically valid for all tissues, COOLAIR forms or temperature regimes; fixed-cell smFISH is not live tracking.

COOLAIR paper, cold-response paper, quantitative imaging paper. The third paper appeared online in December 2022 and in its 2023 issue; these are one study. The paper discussion is based on primary abstracts and selected available results/discussion; complete methods, supplementary evidence and independent replication are not covered. Authorship does not assign all experimental work to the principal investigator or establish supervision quality.

The group's PlantRNA-FM paper adds evidence of computational breadth: its 2024 work integrates sequence and predicted structure from 1,124 plant species and interprets translation-associated motifs. These benchmarks and validations do not make it a validated COOLAIR-localisation predictor. AI is broader lab context, not a newly invented compulsory aim of this PhD. Original model paper

JIC's Summer 2025 bioimaging feature describes light/confocal imaging, technical expertise and substantial recent equipment investment. Equipment availability does not establish the right imaging configuration, validated probes, booking hours, analysis support or budget for this student. Discuss these alongside growth facilities for the advertised temperature comparisons and a fallback if a particular isoform is difficult to quantify. Bioimaging platform

Funding, Application and Living Cost

Eligible NRPDTP awardees receive four years of tuition fees, the UKRI maintenance stipend and £5,000 per year RTSG. The latter is research/training support, not personal disposable income. International students can compete, with no more than 30% of the cohort international; that is a quota, not an individual success probability. £21,805 a year is the 2026/27 reference, approximately £1,817.08 monthly by arithmetic; the 2027/28 amount requires confirmation. Funding, eligibility, UKRI terms

The NRPDTP terms available on 23 October 2026 explicitly cover October 2027 entrants: up to £3,500 towards the individual's visa and immigration health surcharge, claimed after enrolment/registration with appropriate evidence. Dependants are excluded. This capped reimbursement is different from ARIES and does not mean all immigration, travel or relocation costs are prepaid or covered; applicants need upfront cash. An older 2026 description does not establish the conditions for the 2027 cohort. Current NRPDTP funding

UEA's 2026/27 postgraduate accommodation table gives 50-week examples of £6,550, £8,925, £9,750 and £10,475, depending on room type. Its typical postgraduate licence is 50 weeks and five days, so the actual offer and dates determine costs. None is a 2027 price or room guarantee. A Norwich Arts £1,000–1,200 monthly city budget is explicitly from 2024, and UEA's cost comparisons also mix years. Build a 52-week budget and separate startup costs; subtracting an old city figure from a future stipend does not establish savings. Accommodation table, historical city budget, UEA costs

Applications go through UEA, with a maximum of three projects and a separate application for each. NRPDTP's personal- and research-statement proformas are mandatory; missing them leads to rejection. Its present linked files still carry 2026 names, despite the current 2027 timetable, so confirm the version downloaded at submission. JIC's generic guidance describes a 500-word personal statement and a research statement replacing a proposal for advertised projects; it must not be used to replace the programme's mandatory forms. Ask how the current portal maps the two instructions. A self-funded research proposal is a different route. NRPDTP steps, statement guidance, JIC guidance

The linked forms ask for personal motivation (100 words), commitment with examples (450), exciting recent research (450) and additional context (450). The research form asks for project motivation (250), relevant skills/experience (250), and an accessible explanation of a complementary paper from a different research group (400), with citation. The Ding-group papers in this dossier do not themselves satisfy the other-group requirement. Sensitive personal adversity need not be expanded in interview. Use true examples that can be explained independently. Linked personal form, linked research form

The project advert does not specify targeted arrangements for underrepresented applicants or a support process following disability disclosure. The NRPDTP forms include an additional-context answer, which the guidance says is available to project reviewers and, if shortlisted, the interview panel; applicants are not asked to expand on it unless they choose. This is not a disability-adjustment procedure; confirm the relevant route with NRPDTP/UEA.

Also prepare a 1–2-page CV, qualifications/transcripts with official English translations, reference details and applicable passport/immigration evidence. At least one referee should be academic; project supervisors are not acceptable referees. JIC says applicants must request the two references. Confirm deadlines and upload handling. Current programme interviews are scheduled for 2, 3 or 4 February 2027. Application guidance, JIC, dates

Applicant Fit, Career Context and Next Actions

The project requires an obtained or expected first-class, 2(i) or equivalent Honours degree in biology, biochemistry, molecular biology, plant science, genetics or a related discipline. The programme's broader consideration of lower-second degrees with relevant postgraduate qualifications or substantial experience should not be assumed to override the project-specific wording. Chinese equivalence and the precise English condition require individual confirmation. The programme permits conditional language evidence before admission; this is not an automatic exemption or confirmation of an individual IELTS score. Project entry conditions, programme eligibility

Relevant preparation includes an honest example of plant/RNA research, microscopy or quantitative analysis, explaining personal contribution, comparison logic and measurement limits. Purely computational interests should be discussed because experimental imaging is central; immediate commercial breeding outcomes are not advertised.

A JIC Ding-group postdoctoral advert, closed on 23 July 2026, connects RNA structure and function, plant experiments, bioinformatics and student mentoring. It is a concrete example of a research role using this combination of skills, not a current vacancy, promised postdoctoral position or forecast of demand or salary when this doctorate ends. Closed role

Before applying, confirm degree/English equivalence, deadline hour, current forms and the JIC/NRPDTP portal instructions. At interview, prioritise the new localisation question, isoform measurement readiness, image analysis and thermal-history interpretation, individual support and resource allocation. Before accepting, obtain four-year international fee and stipend terms, reimbursement conditions and timing, housing and PIPS arrangements, and image/data/code, authorship and intellectual-property rules. These answers turn the strong scientific match into an assessable individual doctoral plan.
