“…This cooperation has been effected by several national and international cooperative projects and has allowed the close interaction between geneticists, phytopathologists, physiologists and producers, as recommended by many authors Porta-Puglia et al, 1994). Root rots and wilt diseases of grain legumes have been addressed at several international conferences and by specific reviews with emphasis on effective screening techniques and sources of resistance (Grünwald et al, 2004;Jiménez-Díaz et al, 1993b;Kraft & Kaiser, 1993;Kraft et al, 1994;Nene & Reddy, 1987). In the following sections, progress toward improved screening methods for resistance to the major fungal pathogens of grain legumes that are soil-borne and the development of new varieties that are resistant will be illustrated and discussed in detail.…”

Soil-borne fungal diseases are among the most important factors, limiting the yield of grain legumes in many countries worldwide. Root rot, caused by Aphanomyces euteiches, Rhizoctonia solani, Fusarium solani and wilt, caused by several formae speciales of Fusarium oxysporum are the most destructive soil-borne diseases of pea, chickpea, lentil, fababean and lupin. The most effective control of these diseases is achieved through the use of resistant varieties. In this paper, recent advances in conventional and innovative screening methods for disease resistance are presented. Many grain legume accessions, which are maintained in national and international germplasm collections, have been evaluated for disease resistance and numerous resistant varieties have been released following incorporation of identified resistance genes from these sources. Recent identification of molecular markers tightly linked to resistance genes has greatly enhanced breeding programs by making marker assisted selection (MAS) possible and allowing the development of varieties with multiple disease resistance. Progress in the understanding of the biology of soil-borne fungal pathogens of grain legumes is also reviewed with particular reference to the genetic structure of their populations, diagnosis and host-pathogen interaction.

“…The crops considered to be most susceptible to Aphanomyces root rot in the US are pea (Pisum sativum), alfalfa (M. sativa), snap bean (Phaseolus vulgaris), and red clover (Trifolium pratense) (Delwiche et al 1987;Grünwald et al 2004;Papavizas and Ayers 1974;Holub et al 1991;Stuteville and Erwin 1990;Tofte et al 1992). Isolates of A. euteiches are variable in pathogenicity and virulence on these different host species, and host preference among isolates has been reported.…”

Aphanomyces euteiches (races 1 and 2) causes root rot of alfalfa; however, its population biology and distribution are poorly understood where alfalfa is a major crop. The objectives of this study were to (1) characterise the distribution and frequency of races of A. euteiches in Illinois alfalfa fields, (2) determine host range of A. euteiches on cultivated and native legumes, and (iii) to describe genetic diversity and population genetic structure of A. euteiches in alfalfa fields. To accomplish this, soil samples (n= 103) were collected from 30 alfalfa fields in 18 Illinois counties. Using the susceptible cv. 'Saranac', 148 isolates of A. euteiches were baited from the soil. The virulence phenotype of isolates representing all 18 counties was tested, and 54% were R1 and 46% were R2. Both races were detected in 61% of the counties, whereas only R1 was detected in 22% and R2 in 17%. Thirteen legume hosts for isolates from alfalfa fields were identified based on symptoms and/ or production of oospores in roots. In addition to six previously known hosts, seven species were susceptible to infection: kura clover, purple prairie clover, white prairie clover, ladino clover, hairy vetch, Canadian milk vetch, and Illinois tick trefoil. AFLP analysis revealed high levels of genetic diversity among the isolates from different fields and counties and a lack of genetic structuring of populations based on race or geographical origin. The results suggest that populations of A. euteiches in alfalfa fields are diverse, often composed of races 1 and 2, and create risk for alfalfa and to multiple cultivated and native legume species.

“…Alternative strategies such as virus-specific antibodies have also been successfully applied, for review see Prins et al (2008). Surprisingly, the physiology of compatible plant-virus interactions is less understood despite the fact that the damage of crops by disease results in a significant economic loss in agriculture worldwide (Grünwald et al 2004;Love et al 2005).…”

“…mainly in temperate regions. Viral particles are transmitted in a circulatory manner within a host thus causing severe symptoms in juvenile plants, or attenuated ones in adult plants infected after onset of bloom (Grünwald et al 2004). Commercially grown pea cultivars still lack the resistance to PEMV, because breeding is complicated by the fact that pea enation mosaic is caused by two mutualistic RNA viruses.…”

(2013): Reactive oxygen and nitrogen species and hormone signalling in systemic infection of pea by Pea enation mosaic virus. Plant Protect. Sci., 49: 105-119.The physiological responses of pea plants during 40 days of compatible interaction with Pea enation mosaic virus (PEMV) were evaluated. PEMV induces systemic changes in the concentration of phytohormones. At 5 days post inoculation (dpi), a simultaneous increase in abscisic acid (ABA) level and a decrease in salicylic acid (SA) level was observed, which is known to be involved in the suppression of hypersensitive reaction. In our pathosystem it preceded the virus presence in the systemic leaves. PEMV induces the accumulation of ABA, SA and Hsp70 and enhances peroxidase (POX) activity at 15 dpi, when it is already transmitted throughout the plant. The formation of enations was preceded by a local accumulation of nitric oxide, which was followed by the appearance of reactive oxygen species, mostly in the vicinity of leaf veins. Such heterogeneity suggests involvement of these molecules in the control of hyperplasia and tissue differentiation.
