A handshake between auxin and gibberellin in the cambium
Hu et al. demonstrate how the interactions of gibberellin and auxin signaling components regulate cambial activity during wood formation in poplar.
By Jian Hu, Changzheng Xu, and Keming Luo
Background: In trees, the vascular cambium is the population of stem cells that laterally divide and as…

GA-GRF module – A key regulator of rice leaf length via spatial cell division control (New Phytol)
Leaf features have undergone significant changes during the course of evolution and domestication owing to ecological adaptations and changes in source-sink dynamics. Therefore, wild relatives of crop plants are important resources for exploring the genetic regulation of leaf features that might not…
