Genome-wide analysis of the SPL transcription factor family and its response to water stress in sunflower (Helianthus annuus).

ABSTRACT: SPL (SQUAMOSA promoter binding proteins-like) are plant-specific transcription factors that play essential roles in a variety of developmental processes as well as the ability to withstand biotic and abiotic stresses. To date, numerous species have been investigated for the SPL gene family, but so far, no SPL family genes have been thoroughly identified and characterized in the sunflower (Helianthus annuus). In this study, 25 SPL genes were identified in the sunflower genome and were unevenly distributed on 11 chromosomes. According to phylogeny analysis, 59 SPL genes from H. annuus, O. sativa, and A. thaliana were clustered into seven groups. Furthermore, the SPL genes in groups-I and II were demonstrated to be potential targets of miR156. Synteny analysis showed that 7 paralogous gene pa
