🧬🌽 RESEARCH 🧬🌽 A new whole-genome assembly of maize identifies a potential regulator of crossover frequency and other effects on expression of A-chromosome genes mediated by the B chromosome - Hloušková et al. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Thrilled to have our paper out in @science.org. Cell division guides plant cell wall formation. Does the reverse hold? We show that bimodal pectin methylesterification, via PME5 mRNA nuclear sequestration, influences plant cell division and cell plate orientation. www.science.org/doi/10.1126/...
