New data on three molecular markers from different cellular genomes in Mediterranean accessions reveal new insights into phylogeography of Pisum sativum L. subsp. elatius (Bieb.) Schmalh.

Abstract

Twelve accessions classified as Pisum sativum subsp. elatius, mostly from West and Central Mediterranean, were analysed for three markers from different cellular genomes: rbcL (plastid genome), coxI (mitochondrial genome) and SCA (nuclear genome). Based on geographical distribution of their allele combinations analysed in this and the earlier study, we suggest a putative history of wild representatives of P. sativum. The ancestor of this species belonged to lineage A (coxI?, rbcL?, SCA f ); it appeared in East Mediterranean, then spread westward most probably during one of the Pleistocene coolings when the sea was smaller, so that representatives of lineage A remained in the Eastern Mediterranean and on the islands of Sicily and Menorca. Mutation leading to the loss of the restriction site for PsiI in coxI-, gave rise to lineage C (coxI-, rbcL?, SCA f ) which spread widely in the Mediterranean and is now found in France, Greece and Ethiopia. Mutation leading to rbcL-gave rise to lineage D (coxI-, rbcL-, SCA f ), now found in Egypt (P. sativum subsp. jomardii) and Spain. Mutational transition of SCA f to SCA s most probably took place in North-Eastern Mediterranean since the resulting lineage B (coxI-, rbcL-, SCA s ) now occupies the Tauro-Caucasian area. In Asia Minor and North Israel, line B met the ancestral line A so that both lines coexist there presently. The lineage B gave rise to the cultivated P. sativum subsp. sativum.

“…A phylogenetic analysis based on the combination of mitochondrial, chloroplast and nuclear genome markers placed the P. sativum accessions in a distinct clade separated from all P. fulvum and P. sativum subsp. abyssinicum accessions (Kosterin and Bogdanova, 2008;Kosterin et al, 2010) and suggested that all wild forms of Pisum sativum should be included in a paraphyletic P. sativum subsp.…”

Abyssinian pea (Lathyrus schaeferi Kosterin nom. nov. pro Pisum abyssinicum A. Br.) is a problematic taxon

“…Он был описан (Braun, 1841) в ранге вида и при нимался многими авторами в этом же ранге (Говоров, 1937;Ellis et al, 1998;Maxted, Ambrose, 2001;Vershinin et al, 2003;Kosterin, Bogdanova, 2008Maxted, Kell, 2009;Jing et al, 2010;Kosterin et al, 2010;Zaytseva et al, 2012Zaytseva et al, , 2015, тогда как иные авторы считают его подвидом посевного гороха P. sativum subsp. abyssinicum (A.…”

Analysis of variability and phylogeny in pisum (Pisum spp.) using digital phenotyping and morphological traits

“…Kosterin et al (2010) pointed to the lineage B of P. sativum subsp. elatius as the origin of the cultivated P. sativum while linage A remained as the wild form of the specie.…”
