PhD Flowering time control in tulip (1.0 FTE)
Utrecht University's Faculty of Science is looking for a PhD Flowering time control in tulip (1.0 FTE). Are you interested? Then please read the full profile and apply.
- Domplein, Utrecht, Utrecht
- Tijdelijk contract / Tijdelijke opdracht
- Uren per week:
- 36 - 40 uur
- € 2222 - € 2840 per maand
Within the project we are looking for two PhD students:
- One PhD student will be appointed at Wageningen University & Research (WUR).
- One PhD student will be appointed at Utrecht University (UU).
The project will be carried out in close collaboration with the breeding company Dümmen Orange.
The PhD students will study be flowering time control in tulip on the “NWO-green” project: “Life Cycle Shortening: The key towards sustainable tulip production”.
Tulip is an important ornamental and iconic flower for the Netherlands, but unfortunately, its breeding is obstructively slow. In plants, reproductive competence is acquired with the transition to adult vegetative development, a process known as vegetative phase change (VPC). Upon perception of floral-inductive signals plants then undergo reproductive phase change (RPC) and flower. In tulip, it takes five till seven years until seeds have grown into a flowering bulb that can be used for a next (back) cross, forming a major hindrance to the development of new cultivars. Therefore, the main goal of this project is to acquire fundamental knowledge on tulip VPC and RPC, enabling ‘life cycle shortening’ and ‘flowering-on-demand’ during breeding and initial propagation of tulips.
The PhD student stationed at UU will study VPC and the PhD student at WUR will investigate the RPC in tulip. Regulatory networks controlling VPC in tulip including meristem competence and source-sink interactions, will be analyzed and unraveled at a molecular (gene expression) and physiological level (sugar availability, signalling, and use). For the RPC, the focus will be on the important PEBP-family of proteins, including FLOWERING LOCUS T (‘Florigen’). How the battle for resources between different organs and meristems is fought at the molecular level, and how this is controlling phase transitions during the tulip life cycle will be the integrating and common research theme of this program. Approaches that will be taken include transcriptome and metabolome analyses, and transient and stable gene inactivation using e.g. CRISPR-Cas9 technology.
We are looking for highly motivated candidate with an MSc degree in Plant (molecular) Biology, who have affinity for plant development, plant physiology and bioinformatics and a strong interest in developing new technologies in a recalcitrant plant species. The candidate should be fluent in written and spoken English, and be able to communicate and work with both academic and industrial partners.
The candidate is offered a full-time position for initially for one year after which a go/no go decision will be taken on an extension for an additional three years. Gross salary per month €2,222 (P-scale Collective Labour Agreement Dutch Universities) in the first year rising to €2,840 (P-scale) per month in the fourth year for a fulltime appointment. The candidate will be based at the Laboratory for Molecular Biology.
Salaries are supplemented with a holiday bonus of 8 % and a year-end bonus of 8.3 % per year. We offer a pension scheme, collective insurance schemes and flexible employment conditions (multiple choice model). The research group will provide the candidate with necessary support on all aspects of the project. More information is available at: working at Utrecht University.
