POLYMORPHISM OF PEA STORAGE PROTEIN CONVICILIN
Pea convicilin could hinder physico-chemical properties of protein isolates. Pea accessions
without convicilin or with its unusual isoforms could be used in pea breeding on high quality
of storage proteins. Polymorphism of convicilin was studied with use of 60 accessions of
genus Pisum L. Standard SDS-PAGE electrophoresis was used for separation of storage
proteins. In total, four isoforms of convicilin were revealed. They were located on positions
14, 15, 16 and 17 of electrophoretic spectra. Isoform 15 was found with high frequency
(0.35). The frequency of isoform 17 was equal to 0.32. Differences between cultivated and
wild pea accessions on frequency of convicilin isoforms were determined. Among 6 breeding
lines and varieties of Р. sativum only two (14 and 17) isoforms were revealed. Isoform 17
was represented with the highest frequency (0.83). In wild subspecies of Р. sativum (24
accessions) only three (15, 16, 17) isoforms were found. Isoform 15 had the highest
frequency (0.6). In accessions of wild species Р. fulvum all four revealed isoforms of
convicilin were represented. Isoform 15 was found preferably (0.59). In variety Aest
electrophoretic analysis revealed one seed which did not contained convicilin. This seed was
characterized by distinguished from other seeds spectrum.

ABSTRACT
Pea convicilin could hinder physico-chemical properties of protein isolates. <...> Pea accessions
without convicilin or with its unusual isoforms could be used in pea breeding on high quality
of storage proteins. <...> Polymorphism of convicilin was studied with use of 60 accessions of
genus Pisum L. Standard SDS-PAGE electrophoresis was used for separation of storage
proteins. <...> Differences between cultivated and
wild pea accessions on frequency of convicilin isoforms were determined. <...> Among 6 breeding
lines and varieties of Р. sativum only two (14 and 17) isoforms were revealed. <...> In accessions of wild species Р. fulvum all four revealed isoforms of
convicilin were represented. <...> In variety Aest
electrophoretic analysis revealed one seed which did not contained convicilin. <...> This seed was
characterized by distinguished from other seeds spectrum. <...> The genus Pisum L. contains the two species: P. sativum L., the cultivated pea, and P.
fulvum Sibth. et Smith, the red-yellow pea. <...> Species Р. sativum L. includes 6 subspecies:
elatius (Bieb.) Schmalh., syriacum (Boiss. et Noe) Berger, abyssinicum (A. Br.) Berger,
transcaucasicum Makash., asiaticum Govorov и sativum [11]. <...> Electrophoresis of pea storage proteins was used for the identification of various
genotypes, characterization of genetic diversity and in taxonomy [9, 12]. <...> The species P.
fulvum has recently considered as a perspective object of research [4, 14]. <...> In compare to P.
fulvum interest in wild subspecies of cultivated pea was underestimated. <...> Vicilin and legumin produce proteins gels of high quality. <...> But convicilin
could hinder physico-chemical properties of protein isolates. <...> Innovative varieties of pea should be
with high protein quality. <...> Objective of current research was to study polymorphism <...>
