Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

Seed-Specific Saponin Biosynthesis in Medicago

Ribeiro, Lacchini et al. discover a seed-specific transcription factor that helps determine the composition of the defense compounds saponins in developing Medicago truncatula seeds. Plant Cell https://doi.org/10.1105/tpc.19.00609  By Elia Lacchini, Alain Goossens, and Jacob Pollier VIB-UGent…

Predicting Gene Regulatory Networks

Zhou et al. develop and test potential gene regulatory networks in maize. Plant Cell https://doi.org/10.1105/tpc.20.00080 By Peng Zhou and Nathan Springer Background: Transcription factors (TFs) play critical roles in regulating the expression of genes. A single TF can control the expression of…

How Light Activates the Plant Circadian Clock

Liu et al. discover how members of the photosensory-signaling pathway orchestrate circadian clock gene expression to regulate plant responses to daily changes in the light environment. Plant Cell https://doi.org/10.1105/tpc.19.00981  Background: Plants use an endogenous time-keeping mechanism known…

Multilayered Regulation in Senescence

Sakuraba et al. show the existence of multilayered regulation systems for the rice ONAC054 transcription factor, which is involved in abscisic acid-induced leaf senescence in rice. Plant Cell https://doi.org/10.1105/tpc.19.00569 By Nam-Chon Paek, Department of Plant Science, Seoul National University,…
