Genome-wide identification, evolution, and expression analysis of the NAC gene family in chestnut ().

The NAC gene family is one of the most important transcription factor families specific to plants, responsible for regulating many biological processes, including development, stress response, and signal transduction. However, it has not yet been characterized in chestnut, an important nut tree species. Here, we identified 115 genes in the chestnut genome, which were divided into 16 subgroups based on the phylogenetic analysis.

Genome-wide identification, evolution and expression profiles analysis of bHLH gene family in .

The basic helix-loop-helix (bHLH) transcription factors (TFs) gene family is an important gene family in plants, and participates in regulation of plant apical meristem growth, metabolic regulation and stress resistance. However, its characteristics and potential functions have not been studied in chestnut (), an important nut with high ecological and economic value. In the present study, 94 were identified in chestnut genome, of which 88 were unevenly distributed on chromosomes, and other six were located on five unanchored scaffolds.

Genome-wide identification and characterization of the gene family and their function in starch accumulation in Chinese chestnut ( Blume).

The transcription factors of basic leucine zipper (bZIP) family genes play significant roles in stress response as well as growth and development in plants. However, little is known about the gene family in Chinese chestnut ( Blume). To better understand the characteristics of s in chestnut and their function in starch accumulation, a series of analyses were performed including phylogenetic, synteny, co-expression and yeast one-hybrid analyses.
