Review: Seed Mucilage Evolution: Diverse Molecular Mechanisms Generate Versatile Ecological Functions for Particular Environments ($) (Plant Cell Environ.)

Plants with myxodiaspory release mucilage upon imbibition of seeds (myxospermy, e.g., Arabidopsis thaliana) or fruits (myxocarpy, e.g., Linum usitatissimum). This ability appears in several angiosperm families, but its evolutionary origin has seldom been studied. In this review, Viudes et al. synthesize our…

Comparative profiling examines roles of DNA regulatory sequences and accessible chromatin during cold stress response in grasses

, ,
Physical 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…
