Xylem vessels have a distinct secondary cell wall (SCW) formation, where the metaxylem stage contains a characteristic pit pattern. The hemicellulose xylan is an important component of the SCW, functioning as a crosslinking polymer that coats cellulose microfibrils and interacts with other SCW components. However, the xylan initiation mechanism was unknown. Here, Wang et al. […]

Plants use starch in leaf chloroplasts to fuel their growth and metabolism during the night. In Arabidopsis, nighttime starch degradation is tightly regulated; the degradation rate is linear and adjusts to both the availability of starch and length of night, so that most but not all the starch is used up by dawn. The rate, […]
Photosynthesis is an attractive target for improving crop yields, and tailoring downstream photosynthesis-associated metabolism is a relatively unexplored path for achieving this. Chlorella ohadii is the fastest growing photosynthetic organism identified, has high photosynthetic rates, and can survive extreme illumination levels. Here, Treves et al. show how higher metabolic flux in C. ohadii could explain […]
In Arabidopsis, NONEXPRESSOR OF PR GENES 1 (NPR1) plays an important role in the antagonistic crosstalk of salicylic acid (SA) and jasmonic acid (JA) signalling. It activates SA-induced genes that protect against biotrophic pathogens and suppresses JA-induced genes that protect against necrotrophic pathogens. The biotrophic Pseudomonas syringae pv. tomato overcomes the plant’s SA-induced immune response […]
