Just one new paper this week, but it’s from Warwick University’s Bill Finch-Savage. Bill is speaking at the UK Plant Sciences Federation conference in April. If you haven’t registered your place at this event yet, you can do so here:


  • Footitt S, Clay HA, Dent K and Finch-Savage WE. Environment sensing in spring-dispersed seeds of a winter annual Arabidopsis influeces the regulation of dormancy to align germination potential with seasonal changes. New Phytologist, 21 January 2014. DOI: 10.1111/nph.12694.

This paper adds to current knowledge of seed dormancy cycling, which is crucial in the lifecycle timing of many plants. Using the winter annual Arabidopsis thaliana ecotype Cvi, the team buried seeds in spring fields soils, and recovered these monthly to assess their molecular eco-physiological responses. Changes in the expression of DOG1 and MFT, as well as abscisic acid and gibberelling signaling, combine to align germination potential with the optimum climate space for seedling emergence.
