Genome-Wide Analysis of Basic Helix-Loop-Helix Transcription Factors to Elucidate Candidate Genes Related to Fruit Ripening and Stress in Banana ( L. AAA Group, cv. Cavendish).

The basic helix-loop-helix (bHLH) proteins are a superfamily of transcription factors (TFs) that can bind to specific DNA target sites, playing a central role in a wide range of metabolic, physiological, and developmental processes in higher organisms. However, no systemic analysis of bHLH TFs has been reported in banana, a typical climacteric fruit in tropical and subtropical regions. In our study, 259 MabHLH TF genes were identified in the genome of (A genome), and phylogenetic analysis indicated that these MabHLHs could be classified into 23 subfamilies with the bHLHs from rice and .

Molecular characterization and expression analysis of S1 self-incompatibility locus-linked pollen 3.15 gene in Citrus reticulata.

Gametophytic self-incompatibility (GSI) is controlled by a highly polymorphic locus called the S-locus, which is an important factor that can result in seedless fruit in Citrus. The S1 self-incompatibility locus-linked pollen 3.15 gene (S1-3.

Cloning and expression analysis of S-RNase homologous gene in Citrus reticulata Blanco cv. Wuzishatangju.

S-RNase-based self-incompatibility is the most widespread form of genetically controlled mate selection in plants and that S-RNase controls pollination specificity in the pistils. 'Wuzishatangju' (Citrus reticulata Blanco), a nature bud mutant from a self-compatible (SC) cultivar 'Shatangju', displays gametophytic self-incompatibility (GSI). In this study, full-length sequences of cDNA and DNA of the S-RNase homologous gene were obtained from 'Wuzishatangju' and 'Shatangju'.
