An insight into the ontogenetic pattern observed among NQHVVN-containing transcripts found in varying ages of the coconut endosperm

Abstract

Coconut oil starts to accumulate in the endosperm 6-7 months after pollination suggesting a time-dependent pattern of expression among fatty acid genes. NQHVVN-containing transcripts were readily amplified from varying ages of coconut endosperm following an ontogenetic pattern. Two amplified bands were detected at the 5-6- and 6-7-month old coconut endosperms whereas no bands were amplified at the 4-5- and 7-8-month old coconut endosperms following the perceived ontogenetic pattern. In silico analyses of the three sequenced 3'UTR variants show Iso1 possessing an IRES-like motif, Iso2a, a K-box-like and NUE and Iso2b, a Brd-box-like, and an IRES-like motif. K- and Brd-boxes are known sites for miRNA attachment insinuating the involvement of miRNAs in TE ontogenetic expression.
