ARABIDOPSIS RESEARCH ROUND-UPARABIDOPSIS RESEARCH ROUND-UP

27th Feb 2014

This week’s Arabidopsis Research Round-Up is short and sweet – just one Annals of Botany paper today from Ziyue Huang, Steven Footitt and Bill Finch Savage at the University of Warwick’s Crop Centre.

 

  • Huang Z, Footitt S and Finch-Savage WE. The effect of temperature on reproduction in the summer and winter annual Arabidopsis thaliana ecotypes Bur and Cvi. Annals of Botany, 25 February 2014. DOI: 10.1093/aob/mcu014.

Members of the Seed Science group at the University of Warwick compared and contrasted two Arabidopsis thaliana ecotypes: Cape Verdi Isle (Cvi; adapted to a hot, dry climate) and Burren (Bur; adapted to a cool, dry climate). Grown in controlled environments that mimicked the ecotypes’ natural environment, measurements were taken to determine pollen viability, the development of floral structure, and germination at 10 and 25°C in the light to determine dormancy status. Dormancy was reduced in both ecotypes by high temperature in the maternal environment, and seed yield was negatively affected in both, however in Bur, this reduced seed yield was a result of altered floral development rather than reduced pollen viability.
