Unveiling the wheat NTP gene family: insights from genome-wide identification and TaNTP6 haplotype analysis.

ABSTRACT:

Background

Nucleotidyl transferase proteins (NTPs) regulate RNA homeostasis by mediating templated-independent nucleotide additions to RNA termini, thereby being implicated in crucial roles during plant growth, development, and stress responses. However, investigations of the NTP gene family have been limited to few plants, with NTP genes in wheat remaining uncharacterized.

Results

In this study, we identified 34 TaNTP genes in wheat and classified them into three phylogenetic groups (G1-G3). All 20 segmental duplication events occurred specifically in G3. G3 TaNTPs contain unique motifs, while G1 members possess an extra PAP association domain absent in G2 and G3. Protein interaction networks also supported group divergence, with G1 and G3 proteins forming separate modules
