“…It has also been reported that E. trifolii causes powdery mildew in peas and Lathyrus spp. It is severe only in late-planted nurseries in Cordoba and, normally, in India with higher temperatures during the crop season [24,[32][33][34][35]. This is also what we found on faba beans, with infection only occurring in late-planted nurseries.…”

Faba bean (Vicia faba) is a temperate grain legume of major importance for food and feed. Powdery mildews are an important group of diseases in many crops, although in faba bean, it is still considered to be of only minor and local relevance. Here, we report the occurrence of powdery mildew in southern Spain, which was identified through ITS sequencing as Erysiphe trifolii. Resistance screenings allowed the identification of a wide range of responses to the disease, with accessions BPL-710 and ILB-4708 outstanding due to their high levels of resistance. Histological studies showed that the mechanisms of resistance may involve the inhibition of germination and impairment of fungal development, as shown by a limited number of primary and secondary hyphae compared to those of the susceptible accessions. This work permitted a better understanding of the interaction of faba bean and powdery mildew, laying the ground for breeding programs for resistance if needed in the future.

“…Resistance to Fusarium crown rot also has been widely reported in wheat and barley, in most cases being associated with non-pathogen-specific quantitative trait loci (QTLs) [44]. Similarly, QTLs associated with resistance to Fusarium root rot have also been identified in peas [45,46], as has a partial resistance or tolerance to root rot in soybeans [42]. There are limited reports, however, of a resistance or an enhanced tolerance in faba beans [47], canola [29], lentils [48], or lupine [49].…”

Fusarium proliferatum is associated with the root rot of many plant species, but knowledge of its impact on western Canadian field crops is limited. This study assessed the host range of this fungus and its effect on plant emergence, plant height, and shoot and root dry weights in repeated greenhouse experiments with wheat, barley, faba beans, peas, lentils, canola, lupine, and soybeans. Infection was confirmed via PCR, and principal component analysis determined the utility of different parameters in assessing host responses. All crops were at least partly susceptible, developing mild to severe disease at the seedling and adult stages, and showing significant reductions in growth. In general, the barley and wheat demonstrated higher tolerances to infection, followed by the faba bean and the pea. The soybean, canola, lupine, and lentil were most susceptible. The canola and the soybean were particularly vulnerable to F. proliferatum at the pre-emergence stage, while infection greatly reduced the lentil’s biomass. Reductions in the barley’s emergence and other growth parameters, however, occurred only under a high inoculum concentration. Variability in root rot severity among cultivars of the same crop indicated some diversity in host reactions within species. Nonetheless, the absence of fully-resistant crops may pose challenges in managing F. proliferatum in western Canadian cropping systems.

Pea is an important temperate legume crop providing plant-based proteins for food and feed worldwide. Pea yield can be limited by a number of biotic stresses, among which, rust represents a major limiting factor. Some efforts have been made to assess the natural variation in pea resistance, but its efficient exploitation in breeding is limited since the resistance loci identified so far are scarce and their responsible gene(s) unknown. To overcome this knowledge gap, a comprehensive Genome-Wide Association Study (GWAS) on pea rust, caused by Uromyces pisi, has been performed to uncover genetic loci associated with resistance. Utilizing a diverse collection of 320 pea accessions, we evaluated phenotypic responses to two rust isolates using both traditional methods and advanced image-based phenotyping. We detected 95 significant trait-marker associations using a set of 26,045 DArT-seq polymorphic markers. Our in-silico analysis identified 62 candidate genes putatively involved in rust resistance, grouped into different functional categories such as gene expression regulation, vesicle trafficking, cell wall biosynthesis, and hormonal signalling. This research highlights the potential of GWAS to identify resistance sources, molecular markers associated with resistance and candidate genes against pea rust, offering new targets for precision breeding. By integrating our findings with current breeding programs, we can facilitate the development of pea varieties with improved resistance to rust, contributing to sustainable agricultural practices and food security. This study sets the stage for future functional genomic analyses and the application of genomic selection approaches to enhance disease resistance in peas.
