The Squamosa Promoter Binding Protein (SBP) family comprises plant-specific transcription factors widely distributed across green plant lineages and holds significant value for agricultural improvement by regulating key traits including yield, flowering, and stress tolerance. Here, we performed a genome-wide analysis of Medicago truncatula and identified 22 SBP-box genes (MtSBP). These genes are irregularly distributed across seven chromosomes, with chromosome 6 devoid of any SBP-box gene. Sequence alignment confirmed that all MtSBP proteins share conserved nuclear localization signals and two zinc finger structures essential for transcriptional regulation. Phylogenetic analysis grouped thes... More >

Heat shock transcription factors (HSFs) act as transcriptional regulators that mediate the defense responses against heat stress. Castanea dentata plays a major role in sustaining forest and landscape ecosystems and also exhibits medicinal properties. In this study, we identified 23 CadenHSFs genes from the genome of C. dentata. In silico approaches were employed to analyze gene structure, conserved domains, chromosomal locations, motif organization, comparative evolutionary analyses, synteny analyses, subcellular localization, and cis-regulatory element analysis. Cis-regulatory element analysis revealed that the promoters of CadenHSFs genes are associated with stress responses, light signal... More >
