Review: Molecular mechanism of compound leaf pattern establishment in Medicago truncatula

Leaf is the main place for plants to carry out photosynthesis and resist pests and diseases, showing great diversity in morphology, so it is a good model for studying the complex morphogenesis and evolution of plants

This article reviews the key genes and hormonal signals during the establishment of the compound leaf pattern of Medicago truncatula, and compares the similarities and differences in the developmental mechanisms of compound leaves among different species

Master student Mo Xiaoyu and associate researcher He Liangliang of Banna Botanical Garden are the first authors, and researchers He Liangliang and Chen Jianghua are the corresponding authors of the paper

The key mechanism of the establishment of the compound leaf pattern of Medicago truncatula: ( A ) SGL1/LFY pathway regulates the activity of compound leaf stem cells; ( B ) The action model of auxin; ( C ) The regulatory mechanism of leaflet boundary division; ( D ) The dorsal and ventral poles of compound leaves Sexual maintenance and regulation
