TL;DR: Analysis of motif enrichment, as well as comparison of transcription factor families showing altered expression over the time course, identify clear groups of TFs active at different stages of leaf development and senescence, which will underpin the development of network models to elucidate the process of Senescence.

TL;DR: It is reported on a comparative seed biology study with the close Brassicaceae relatives Lepidium sativum and Arabidopsis thaliana showing that ethylene biosynthesis and signaling regulate seed germination by a mechanism that requires the coordinated action of the radicle and the endosperm cap.

TL;DR: This work demonstrates that the perception of daylength in Arabidopsis relies on adjustments of the phase angle of circadian rhythms relative to the light/dark cycle, rather than on the measurement of the absolute duration of light and darkness.

TL;DR: A programme of work is reported that identifies key seed vigour traits that are required for predictable seedling establishment followed by a quantitative genetic analysis to identify loci that influence them and a way forward for marker and candidate gene identification is outlined that uses a translational approach to exploit the colinearity between B. oleracea and the model plant Arabidopsis.

TL;DR: Inhibitors of the aspartic, serine, and cysteine proteases reduced the number of isolated CAPs in which weakening developed, and inhibition of the 26S proteasome resulted in its complete cessation, indicating that targeted protein degradation is a major control point for endosperm weakening.
