Abstract
Nuclear factor-Y (NF-Y) has been known as one of the plant-specific
transcription factors that play key roles in numerous biological processes during
the growth and development of plant species. In this study, a comprehensive
analysis of NF-YC sub-units in grain amaranth (Amaranthus hypochondriacus)
was carried out based on the bioinformatics approaches. Firstly, a total of five
members of the NF-YC sub-units was reported in the grain amaranth. Its structural
analyses revealed that the NF-YC sub-units were variable in physic-chemical
properties, like protein sizes, molecular masses, isoelectric point, instability index,
and grand average of hydropathy. Of our interest, the expression profiles of genes
encoding NF-YC sub-units in various tissues/organs during the growth and
development of grain amaranth. We found that three genes, including AhNF-YC01,
AhNF-YC04, and AhNF-YC05 were highly expressed in leaf, root, floral, immature
seed, and stem tissues. Interestingly, AhNF-YC05 was exclusively expressed in leaf
and stem tissues. Taken together, our study could provide a solid understanding for
further functional characterization of genes encoding NF-YC sub-units in grain
amaranth.
