Abstract
A novel cDNA of a SF21-like protein or NDR-like protein (EgNDL) from Elaeis guineensis Jacq. is 1,044 bp in length
and encodes a putative protein with a 347-amino-acid open reading frame. The EgNDL showed 93% identity to the pollenspecific
SF21-like protein of Phoenix dactylifera and also showed 79% identity to the NDL protein of Theobroma cacao.
Expression analysis of the EgNDL gene in various tissues showed that EgNDL was expressed in the anthers, pistils,
mesocarp and leaves. The high expression of EgNDL among three oil palm varieties was significantly expressed in Pisifera
(P<0.05), which is commonly used as a male parent in crosses. Computational tools were used to predict the protein and
concluded that EgNDL is a putative membrane protein that may function in a signal transduction pathway during pollen
development. In this context, knowledge regarding EgNDL and its potential role in plant developmental processes will
benefit oil palm breeding programs
