Identification and characterisation of incompatibility factors inHamelia patensJacq. (Rubiaceae)

Differential Activity of Four Selected Enzymes in the Pistils and Pollen Grains of Two Varieties of Hamelia Patens Jacq. (Rubiaceae) Following Compatible and Incompatible Pollination.

“…Seeds are important for the plant forpropagation of the progeny and for a breeder to assessthe results of breeding while developing new cultivars.Louis and Radhamany(2009)and Louis et al (2012)reported RNase based gametophytic incompatibility in H.patens.Since legitimateand illegitimate pollinations are affected by alternations in the metabolic status of stigma and stylartissues (Dhaliwal1985), it would be imperative to study the changes in the enzyme activities of stigma-style tissues following compatible and incompatible pollination. Since the enzymes control biochemical reactions, and their synthesis is under the control of specific gene(s), any change in the activity of an enzyme would reflect in the pattern of gene expression and corresponding metabolic events in the cell.…”
