Abstract
Nuclear factor-Y (NF-Y) are transcription factors that play vital role in various developmental processes such as flowering, embryogenesis, root formation, nodulation and stress tolerance. In the present study, 27 NF-Y genes were identified in Dendrobium catenatum which were grouped into three sub-families: DcNF-YA (5), DcNF-YB (10) and DcNF-YC (12), on the basis of presence of specific conserved domains. The phylogenetic relationship between DcNF-Y protein sequences with their orthologs in Vanilla planifolia and Arabidopsis thaliana confirmed the classification of these proteins into the specified three groups. Physico-chemical characterization reported a wide range in the protein length (111 to 433 amino acids), with DcNF-YAs being longer than the others. Strong interaction between most of the DcNF-Y proteins suggests towards the formation of complexes which might be playing a role in different developmental processes. Gene architectural studies predicted the presence of multiple (3–6) introns in DcNF-YA in contrast with the intron-less status of majority of DcNF-YB and DcNF-YC genes. The abundance of stress related cis-regulatory elements in the promoter regions of DcNF-Y genes indicate the potential of these genes in stress tolerance. Additionally, variable expression of these genes in diverse tissues point towards their widespread role in growth and development. This work can act as a harbinger for functional characterization of NF-Y genes with a view for genetic improvement in Dendrobium catenatum Lindl.

期刊介绍:
Plant Gene publishes papers that focus on the regulation, expression, function and evolution of genes in plants, algae and other photosynthesizing organisms (e.g., cyanobacteria), and plant-associated microorganisms. Plant Gene strives to be a diverse plant journal and topics in multiple fields will be considered for publication. Although not limited to the following, some general topics include: Gene discovery and characterization, Gene regulation in response to environmental stress (e.g., salinity, drought, etc.), Genetic effects of transposable elements, Genetic control of secondary metabolic pathways and metabolic enzymes. Herbal Medicine - regulation and medicinal properties of plant products, Plant hormonal signaling, Plant evolutionary genetics, molecular evolution, population genetics, and phylogenetics, Profiling of plant gene expression and genetic variation, Plant-microbe interactions (e.g., influence of endophytes on gene expression; horizontal gene transfer studies; etc.), Agricultural genetics - biotechnology and crop improvement.
