Almost all active plant retroelements are known to be induced by various biotic and abiotic stresses. Here, we show the presence of transcriptionally active Ty1-copia like retroelements in chickpea and their induction in response to abiotic stress. Eight Ty1-copia retrotransposon like mRNA sequences were reverse transcribed, amplified, cloned and characterized from stressed plants. These mRNA sequences were not detected in chickpea plants grown under normal conditions. Basing on the similarity analysis, these RT transcript sequences were classified into three families. It is proposed that all sequences except CARE7 might be transcript sequences of functional retrotransposons. The mRNA sequence CARE3 shows 99% nucleotide identity to a genomic Ty1-copia like sequence present in the Genbank with accession no. AJ535883.
