Brazil) cDNA encoding a putative rubredoxin-like protein (MaRd1) was obtained from total RNA isolated from cold-treated banana leaves using rapid amplification of cDNA ends (RACE) technique. MaRd1 cDNA contained 597 nucleotides encoding 198 amino acids in the open reading frame. MaRd1 protein showed 56% amino acid identity with that of Pyrococcus furiosus rubredoxin (P24297). A chloroplast transit peptide and a transmembrane region were detected at the N-terminus and the C-terminus, respectively, of the deduced amino acid sequence of MaRd1 gene. Southern blotting revealed the occurrence of at least two copies of MaRd1 in the banana genome. Real time quantitative RT-PCR analysis revealed that the expression of MaRd1 gene was mainly in leaves, pseudo-stems and immature fruits, while it was barely detectable in roots and flowers. Cold and salt stresses induced higher levels of MaRd1 transcript accumulation in leaves. This finding indicated a role of MaRd1 in the response to these abiotic stresses.}, DOI = {10.32604/phyton.2010.79.163} }
