Currently attending the annual meeting of the Chilean Society of Plant Biologists 🌱🇨🇱
Presenting the findings of our recently published article doi.org/10.1111/tpj....
and our next steps with systems biology 🧬

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 🌱

Very excited to share our paper "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...
🌱🧬 Nitrate is not just food. It is a signal. In Arabidopsis, nitrate boosts cell expansion by increasing methylesterified pectin & softening the cell wall. This pathway depends on NRT1.1 & NLP7. #plantscience
