Cold, but not freezing: the ICE-L genome ($) (Current Biology)
Plant Science Research Weekly
When sea water freezes, it forms not a solid mass of ice, but rather a frozen matrix criss-crossed by tiny brine-filled channels. It is within these brine channels in the Antarctic sea ice that the psychrophilic (cold-loving) green alga ICE-L lives. How is it able to thrive in such a seemingly hostile…
Comparative profiling examines roles of DNA regulatory sequences and accessible chromatin during cold stress response in grasses
Research, The Plant Cell, The Plant Cell: In BriefPhysical access to regulatory DNA, including cis-regulatory sequences found within proximal promoters and distal enhancer elements, is a vital property of chromatin. In turn, their access is determined by nucleosome occupancy and post-translational modification of histone proteins. A continuum of chromatin…
Review: Plant small heat shock proteins – evolutionary and functional diversity (New Phytol.)
Plant Science Research WeeklyHeat shock proteins are rapidly induced by heat treatment and were among the first plant genes and proteins characterized in the early days of molecular biology, nearly 40 years ago. Waters and Vierling review the family of small heat shock proteins (sHSPs), which has been especially amplified in plants…
