Review: Linking autophagy to abiotic and biotic stress responses (Trends Plant Sci)($)

Autophagy means “self-eating” in ancient Greek. It’s a process in which cellular components are delivered to lytic vacuoles to be reused. This recycling process promotes abiotic and biotic stress tolerance. In this review, Signorelli et al. highlight in detail plant autophagy in abiotic and biotic stress responses and how these responses are triggered to affect […]

Cuticle is found in the root! The root cap cuticle protects young roots from abiotic stress and helps lateral root outgrowth (Cell) ($)

To adapt to life on land, plants developed lipid-derived modifications on the surface of aerial organs (shoot). The cuticle forms a multi-layered structure of lipid components at the outermost surface of the organ to protect plant cells from environment stresses. Roots, as the organ specialized for the acquisition of water and nutrients, were thought to […]

Understanding leaf shape development and diversity in Brassicaceae (New Phytol) ($)

Many economically important crops are in the Brassicaceae family, such as cabbage, mustard, and the model plant Arabidopsis thaliana. Recently, the systematics of Brassicaceae has assigned most of the species to 52 monophyletic groupings (tribes). However, relationships along the backbone of the phylogeny and among tribes remain largely unknown because of the lack of resolution. […]

Seed size is regulated by siRNAs from Arabidopsis maternal tissue in a spatial-temporal manner ($)(PNAS)

Studying seed development is important for understanding plant evolution and engineering food production. Previous discoveries have shown that maternal small interfering RNAs (siRNAs), which induce RNA-directed DNA methylation (RdDM) through NRPD1-mediated pathway, regulate seed development in Arabidopsis. However, it was ambiguous whether the maternal expression of these NRPD1-siRNAs is from the seed coat (maternal) or […]
