Abstract: | Background Polygalacturonases (PGs) belong to a large gene family in plants and are believed to be responsible for various cell separation
processes. PG activities have been shown to be associated with a wide range of plant developmental programs such as seed germination,
organ abscission, pod and anther dehiscence, pollen grain maturation, fruit softening and decay, xylem cell formation, and
pollen tube growth, thus illustrating divergent roles for members of this gene family. A close look at phylogenetic relationships
among Arabidopsis and rice PGs accompanied by analysis of expression data provides an opportunity to address key questions on the evolution
and functions of duplicate genes. |
