Keep a distance to be different: axillary buds initiating at a distance from the shoot apical meristem are crucial for the perennial lifestyle of Arabis alpina

Summary In many seed plants, perennialism is achieved through axillary buds and side shoots that remain vegetative. This work aimed to analyse the pattern of axillary bud (AB) formation in the perennial model plant Arabis alpina and to study the role of the LATERAL SUPPRESSOR ( AaLAS ) gene. This study combines stereomicroscopic analysis with RNA sequencing to monitor the correlation between patterns of AB formation and gene expression. The role...
