Zhang et al. explore the mechanisms underlying elaborate petal development and specialized character formation in Nigella damascena. Plant Cell https://doi.org/10.1105/tpc.20.00330 By Rui Zhang, Xuehao Fu, Caiyao Zhao, Jie Cheng, Hongyan Shan, and Hongzhi Kong Background: Petals can be simple or…

Being a multicellular organism is not an easy task. Proper functioning of individual cell types with different functions requires coordination of gene expression to determine cell identity, but also regulatory mechanisms to respond to environmental cues. The root may appear simple at first sight, but…

The gardeners among us know that direct sunlight is a prerequisite to obtain full-sized, bright red tomato  (Solanum lycopersicum) fruits. Indeed, light increases the accumulation of yellow and red carotenoid pigments, particularly lycopene, in ripe tomato fruits while it also boosts chlorophyll levels…

Larson et al. examine the interactions between subunits of the exocyst and SNARE complex and the effects of these interactions on trafficking, secretion, and growth. Plant Cell https://doi.org/10.1105/tpc.20.00280   Emily R Larson1,3, Jitka Ortmannová2,4, Naomi A Donald1, Jonas Alvim1, Michael…

Plant seeds store nutrients in the form of protein, starch, and oil to support seed germination and seedling establishment. The seed nutrient reserves are supplied with carbon and nitrogen assimilated in vegetative tissues, where primary metabolism oscillates in a circadian manner (Farré and Weise,…

Rubisco catalyzes the key carboxylation step in photosynthetic CO2 fixation and is probably the most abundant protein on Earth. The enzyme is famous for inefficient catalysis and the habit of binding oxygen instead of CO2 in one out of every four binding events, leading to photorespiration reactions…
