“…Only two recessive genes for resistance to E. pisi, designated as er1 and er2, had been previously described in pea (Heringa et al 1969). Several evidences suggested that the gene Er3, present in P. fulvum, was different from the genes er1 and er2, identified in P. sativum.…”

“…Although the cultivated pea germplasm has been extensively screened for resistance to powdery mildew, only two resistance genes, er1 and er2, have been identified so far (Heringa et al 1969). Generally, single gene-controlled resistances are ephemeral due to the rapid evolution of pathogen virulence.…”

“…In some cases, PMR was proposed to be conferred by the complementary action of two recessive loci (Heringa et al 1969;Kumar and Singh 1981). Nevertheless, these claims based on the resistance expressed on the lines Mexique 4 and S-143, were not corroborated by the later studies of Tiwari et al (1997), Vaid and Tyagi (1997), and Sharma (2003), who reported a monogenic recessive inheritance for the resistance present in these two genotypes.…”

“…Moreover, one single locus-referred to as er1 by Heringa et al (1969)-seems to be responsible for most of the powdery mildew resistances (PMR) identified so far (Sharma 2003).…”

“…A second recessive powdery mildew resistance locus, er2, was identified in lines SVP 951 and SVP 952 (Heringa et al 1969) and JI 2480 (Ali et al 1994;Tiwari et al 1997). This monogenic recessive resistance was shown to be partially or totally broken depending on biotic and abiotic stress factors such as (leaf) age, field versus glasshouse/growth cabinet growing conditions (Heringa et al 1969;Tiwari et al 1997;Fondevilla et al 2006) and temperature (Heringa et al 1969;Fondevilla et al 2006).…”

The alkylating compounds and strong mutagens methylnitrosourea (MNU) and ethylnitrosourea (ENU) were used to widen the genetic variability of pea (Pisum sativum L.) via experimental mutagenesis. Amongst multiple mutations of agronomical interest, for the first time two mutations conferring broad-range resistance to powdery mildew (Erysiphe pisi Syd.) were induced in pea. Mutagenic treatments were carried out on seedlings using a technique that ensures very high mutagenic efficiency. Two-hour exposure of cv. Solara seedlings to chemical mutagens resulted in almost non noticeable lethality and sterility in the M1 generation and very high mutation rates: *39% families with visible mutations in the M2 generation. The influence of the cell cycle phase on the process of mutagenesis was studied in cv. Frilene using a previously developed technique for synchronization of shoot apical meristem cells. The cell cycle phase at which cells were treated apparently did not influence the lethality and sterility in the M1 generation, while the visible mutation rate, assessed in the M2 generation, showed a clear cell cycle dependency. Seedlings treated at the G2 and M phases gave rise to progenies exhibiting the highest mutation rate, over 50% of M2 families with visible mutations. The powdery mildew resistant (PMR) mutant S(er1mut1) was induced by treatment of cv. Solara seedlings for 2 h with ENU, while the PMR mutant F(er1mut2) was induced by treatment of cv. Frilene seedlings with the same chemical mutagen for 1 h during the G2 phase of the cell cycle. The genetic analysis of the novel PMR mutant lines showed that both resistances are inherited as monogenic recessive traits. The performed genetic complementation analyses revealed that both mutations affect the same locus-er1, which determines most of the natural sources of PMR in pea. A project aiming at the isolation of the powdery mildew resistance mutated gene via map based cloning is currently under way.
