Nitrate Defines Shoot Size through Compensatory Roles for Endoreplication and Cell Division in Arabidopsis thaliana Moreno et al. show that nitrate regulates shoot growth by modulating cell size and endoreplication. They identify the LGO gene as a regulatory factor influencing ploidy and cell size, depending on ext...

LGO participates in cell cycle regulation. Years ago, our lab worked with its mutant in the context of nitrate-regulated cell expansion in cotyledons

Also happy to say that Arabidopsis epidermal cells make the cover of @theplantjournal.bsky.social for the issue with our paper, showing that nitrate availability impacts pectin metabolism and cell wall mechanics for growth 🌱

Nitrate modulates pectin metabolism and cell wall mechanics during cell expansion in Arabidopsis Nitrate increases HG abundance and reduces PME activity via NRT1.1- and NLP7-dependent pathways. Enhanced pectin methylesterification softens the cell wall, facilitating cotyledon cell expansion. Thi...

Very excited to share our paper "Nitrate modulates pectin metabolism and cell wall mechanics during cell expansion in Arabidopsis" 🌱
