Abstract:
The members of Poaceae/grass family consists of crops having economical and
agricultural significance such as wheat, rice, maize and sorghum that can adapt to any
terrestrial environment therefore wild progenitors of these crops are great genetic
source of beneficial alleles that can contribute to the vigorous plant growth and biotic
and abiotic stress tolerance/resistance. Hexaploid wheat (Triticum aestivum) has
supreme importance as major crop worldwide providing nutritive food to humans and
fodder to animals. Plants counteract many environmental stresses that pose serious
effects on their growth and development that is why an insight to the computational
analysis can pave the way for understanding of advantageous gene functions which can
be a valuable addition to crop improvement studies. Plant P-class pumps are divided
into five sub-families i.e., P1B, P2, P3A, P4 and P5A type ATPases which play an
important role in transporting cations/lipid complexes across the cell membranes while
maintaining cellular homeostasis. In this research, P-type ATPases from 8 selected
members of Poaceae family were employed for phylogenetic tree construction to
demonstrate their evolutionary relationship. Triticum aestivum P-type ATPases were
analyzed for identification of conserved motifs, gene structure (for intron/exon
positions) and subcellular localization.
