Abstract excerpt
The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics. We used root tip excision to synchronize lateral root development across natural accessions. The resulting phenotypes were analysed using...
