“…It is clear that the proteins responsible for SI response in the short and in the long styles are not identical, neither in their abundance, nor in mass and pI values, which is in agreement with morphological data obtained from fluorescence micrographs (Miljuš-Đukić et al 2003). We can assume that some of them have functions in adhesion to stigma surface, or to the inhibition of pollen tube elongation.…”

Buckwheat (Fagopyrum esculentum Moench) is a heterostylous plant displaying heteromorphic sporophytic selfincompatibility (SI). In order to detect proteins involved in SI, pistils from both long and short styles were isolated and then selfed or cross-pollinated. One-dimensional gel electrophoresis revealed that short pistils 2 h after selfing contained an unique 50 kDa protein. In the two-dimensional electrophoresis two distinct groups of proteins possibly involved in SI response were detected in the short, and one in the long pistils.

“…In consequence, pollen tubes stop at nearly the same distance from the ovary in both morphs. Miljus-Djukic et al [ 90 , 91 ] detected some proteins in the styles 2 h after compatible and incompatible pollinations. The proteins responsible for the self-incompatibility response are not the same in the long and the short styles.…”

The Fagopyrum genus includes two cultivated species, namely common buckwheat (F. esculentum Moench) and Tartary buckwheat (F. tataricum Gaertn.), and more than 25 wild buckwheat species. The goal of breeders is to improve the properties of cultivated buckwheat with methods of classical breeding, with the support of biotechnological methods or a combination of both. In this paper, we reviewed the possibility to use transcriptomics, genomics, interspecific hybridization, tissue cultures and plant regeneration, molecular markers, genetic transformation, and genome editing to aid in both the breeding of buckwheat and in the identification and production of metabolites important for preserving human health. The key problems in buckwheat breeding are the unknown mode of inheritance of most traits, associated with crop yield and the synthesis of medicinal compounds, low seed yield, shedding of seeds, differential flowering and seed set on branches, and unknown action of genes responsible for the synthesis of buckwheat metabolites of pharmaceutical and medicinal interest.

“…The timescale of the SI response in grasses suggests that rapid signalling is already effective while gene expression is gearing up. Protein modification and Ca 2+ flux signalling may well be involved in these rapid signalling events because their role in SI has been well demonstrated in other systems (Giranton et al, 2000;Franklin-Tong et al, 2002;Miljuš-Ðukić et al, 2003).…”

Progress towards elucidating the mechanisms of self-incompatibility in the grasses: further insights from studies in Lolium

From subtracted Lolium immature stigma cDNA libraries derived from S and Z genotyped individuals enriched for SI potential component genes, kinase enzyme domains, a calmodulin-dependent kinase and a peptide with several calcium (Ca(2+)) binding domains were identified. Preliminary findings suggest that Ca(2+) signalling and phosphorylation may be involved in Lolium GSI. This is supported by the inhibition of Lolium SI by Ca(2+) channel blockers lanthanum (La(3+)) and verapamil, and by findings of increased phosphorylation activity during an SI response.
