What is Genome-wide analysis of the switchgrass YABBY family and functional characterization of PvYABBY14 in response to ABA and GA stress in Arabidopsis about?
## Background The small YABBY plant-specific transcription factor has a prominent role in regulating plant growth progress and responding to abiotic stress. ## Results Here, a total of 16 __PvYABBYs__ from switchgrass (__Panicum virgatum__ L.) were identified and classified into four distinct subgroups. Proteins within the same subgroup exhibited similar conserved motifs and gene structures. Synteny analyses indicated that segmental duplication contributed to the expansion of the YABBY gene family in switchgrass and that complex duplication events occurred in rice, maize, soybean, and sorghum. Promoter regions of __PvYABBY__ genes contained numerous cis-elements related to stress responsiveness and plant hormones. Expression profile analysis indicated higher expression levels of many __PvYABBY__ genes during inflorescence development and seed maturation, with lower expression levels during root growth. Real-time quantitative PCR analysis demonstrated the sensitivity of multiple __YABBY__ genes to PEG, NaCl, ABA, and GA treatments. The overexpression of __PvYABBY14__ in __Arabidopsis__ resulted in increased root length after treatment with GA and ABA compared to wild-type plants. ##
