A mutation near the active site of S-RNase causes self-compatibility in S-RNase-based self-incompatible plants

Plant Molecular Biology, 2020
The structurally simplest amino acid glycine could make contribution to nuclease activity of S-RNase and self-incompatibility in S-RNase-based plants. S-RNase is regarded as inhibitor of self-pollen tube in S-RNase-based self-incompatibility plants. Certain residues like histidine are necessary for RNase activity and self-incompatibility; however, it ...

Identification of a non-S RNase, a possible ancestral form of S-RNases, in Prunus

Molecular Genetics and Genomics, 2003
This study identifies and characterizes a basic non-S RNase in the styles with stigmas of sweet cherry (Prunus avium L.), a member of the Rosaceae subfamily Amygdaloideae, which has an RNase-based gametophytic self-incompatibility system. Internal sequences of putative non-S RNases (RNase PA1 and PA2) were determined, and a cDNA for PA1 was obtained ...

Identification of S-RNase and peroxidase in petunia nectar

Journal of Plant Physiology, 2011
Previous SDS PAGE gel analysis of the floral nectars from petunia and tobacco plants revealed significant differences in the protein patterns. Petunia floral nectar was shown to contain a number of RNase activities by in gel RNase activity assay.

S-RNase-like Sequences in Styles of Coffea (Rubiaceae). Evidence for S-RNase Based Gametophytic Self-Incompatibility?

Tropical Plant Biology, 2011
Although RNase-based self-incompatibility (SI) is suspected to operate in a wide group of plant families, it has been characterized as the molecular genetic basis of SI in only three distantly related families, Solanaceae, Plantaginaceae, and Rosaceae, all described over a decade ago.

Basic RNases of wild almond (Prunus webbii): Cloning and characterization of six new S-RNase and one “non-S RNase” genes

Journal of Plant Physiology, 2009
In order to investigate the S-RNase allele structure of a Prunus webbii population from the Montenegrin region of the Balkans, we analyzed 10 Prunus webbii accessions. We detected 10 different S-RNase allelic variants and obtained the nucleotide sequences for six S-RNases.
