Comprehensive identification of PIN and PILS in crape myrtle genomes reveals their putative functions in bud-to-branch development and callus generation
Polar auxin transport in plants is facilitated by influx and efflux transporters encoded by PIN-FORMED (PIN) and PIN-like (PILS) genes, respectively. While the auxin transporter gene families have been extensively studied in various monocot and dicot species, a comprehensive genome-wide analysis of PIN and PILS gene families in Lagerstroemia indica is currently lacking. In this study, we identified 22 LiPIN and LiPILS genes in L. indica genome, distributed across 17 chromosomes. Gene structure and conserved motif analyses revealed relative conservation within the same group. Additionally, we identified 16 syntenic gene pairs in LiPIN and LiPILS genes, with Ka/Ks values below 1 indicating purifying selection during evolutionary processes. Expression profiling indicated that several genes, notably LiPIN3a and LiPILS5b/6a/6b/6c, responded to salt stress. LiPIN1d, LiPIN5, and LiPILS3a were potentially linked to bud-to-branch development in L. indica. Moreover, the expression levels of LiPILS3a and LiPILS5a exhibited significant differences during the callus formation process, indicating their potential as key regulatory factors in this developmental stage. These findings offered new insights into auxin transporter genes in L. indica and enhanced our understanding of their roles in stress tolerance, growth, and development.
期刊介绍：
Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
