What is Overexpression of AHL9 accelerates leaf senescence in Arabidopsis thaliana about?
## Background Leaf senescence, the final stage of leaf growth and development, is regulated by numerous internal factors and environmental cues. Ethylene is one of the key senescence related hormones, but the underlying molecular mechanism of ethylene-induced leaf senescence remains poorly understood. ## Results In this study, we identified one AT-hook like (AHL) protein, AHL9, as a positive regulator of leaf senescence in __Arabidopsis thaliana__. Overexpression of __AHL9__ significantly accelerates age-related leaf senescence and promotes dark-induced leaf chlorosis. The early senescence phenotype observed in __AHL9__ overexpressing lines is inhibited by the ethylene biosynthesis inhibitor aminooxyacetic acid suggesting the involvement of ethylene in the __AHL9__-associated senescence. RNA-seq and quantitative reverse transcription PCR (qRT-PCR) data identified numerous senescence-associated genes differentially expressed in leaves of __AHL9__ overexpressing transgenic plants. ## Conclusions Our investigation demonstrates that __AHL9__ functions in accelerating the leaf senescence process via ethylene synthesis or signalling. ## Supplementary Information The online version contai
