“…The partial dominance of susceptibility over resistance was again confirmed when the mean lesion length of the F 1 generation was compared with their respective mid-parent values. A similar result was also reported by Baswana et al [57] in cauliflower, while overdominance of susceptibility in Brassica napus was delineated by Khan et al [58,59]. Similar to Khan et al [59] and Zhao et al [60], we also observed transgressive segregants for resistance in F 2 and BC 1 P 1 generations of both populations.…”

Similar to Khan et al [59] and Zhao et al [60], we also observed transgressive segregants for resistance in F 2 and BC 1 P 1 generations of both populations. Such transgressive segregants were nearly asymptomatic without any lesion development which may be fixed later in selfing generations and can be utilized as a source of resistance in the future.…”

“…In both populations, estimates of dominance-by-dominance effects (l) were significant and opposite in sign to those of dominance effects alone (h), indicating the role of duplicate epistasis in resistance expression. Similarly, Khan et al [59] also detected the role of dominance × dominance type of digenic interaction for cotyledon resistance in Brassica napus against S. sclerotiorum.…”

Sclerotinia stem rot is one of the utmost important disease of mustard, causing considerable losses in seed yield and oil quality. The study of the genetic and proteomic basis of resistance to this disease is imperative for its effective utilization in developing resistant cultivars. Therefore, the genetic pattern of Sclerotinia stem rot resistance in Indian mustard was studied using six generations (P1, P2, F1, F2, BC1P1, and BC1P2) developed from the crossing of one resistant (RH 1222-28) and two susceptible (EC 766300 and EC 766123) genotypes. Genetic analysis revealed that resistance was governed by duplicate epistasis. Comparative proteome analysis of resistant and susceptible genotypes indicated that peptidyl-prolyl cis-trans isomerase (A0A078IDN6 PPIase) showed high expression in resistant genotype at the early infection stage while its expression was delayed in susceptible genotypes. This study provides important insight to mustard breeders for designing effective breeding programs to develop resistant cultivars against this devastating disease.

“…In Australia, this disease causes up to 24% yield loss. The pathogen attacks cotyledons and leaves in seedlings and stems and leaves in adult plants, causing some key symptoms like water-soaked lesions, necrotic tissues with fluffy white mycelium and sclerotia inside of stems [32]. In rapeseed, a major constraint in production is blackleg disease, caused by ascomycete fungus Leptosphaeria maculans (Lm).…”

The Brassica genus includes one of the 10 most agronomically and economically important plant groups in the world. Within this group, we can find examples such as broccoli, cabbage, cauliflower, kale, Brussels sprouts, turnip or rapeseed. Their cultivation and postharvest are continually threatened by significant stresses of biotic origin, such as pathogens and pests. In recent years, numerous research groups around the world have developed transgenic lines within the Brassica genus that are capable of defending themselves effectively against these enemies. The present work compiles all the existing studies to date on this matter, focusing in a special way on those of greater relevance in recent years, the choice of the gene of interest and the mechanisms involved in improving plant defenses. Some of the main transgenic lines developed include coding genes for chitinases, glucanases or cry proteins, which show effective results against pathogens such as Alternaria brassicae, Leptosphaeria maculans or Sclerotinia sclerotiorum, or pests such as Lipaphis erysimi or Plutella xylostella.

“…), and White Rust (obligate biotrophic oomycete Albugo candida ) [ 22 , 23 ]. These diseases have widely caused a yield loss of 24–50% and economic loss of up to USD 200 million in the B. napus industry, with the potential to wipe out the entire crop where not effectively controlled [ 24 , 25 , 26 , 27 , 28 , 29 ]. The most promising approach to controlling diseases of Brassica is through breeding disease-resistant varieties [ 30 ].…”

Brassica napus (canola/oilseed rape/rapeseed) is an economically important crop, mostly found in temperate and sub-tropical regions, that is cultivated widely for its edible oil. Major diseases of Brassica crops such as Blackleg, Clubroot, Sclerotinia Stem Rot, Downy Mildew, Alternaria Leaf Spot and White Rust have caused significant yield and economic losses in rapeseed-producing countries worldwide, exacerbated by global climate change, and, if not remedied effectively, will threaten global food security. To gain further insights into the host–pathogen interactions in relation to Brassica diseases, it is critical that we review current knowledge in this area and discuss how omics technologies can offer promising results and help to push boundaries in our understanding of the resistance mechanisms. Omics technologies, such as genomics, proteomics, transcriptomics and metabolomics approaches, allow us to understand the host and pathogen, as well as the interaction between the two species at a deeper level. With these integrated data in multi-omics and systems biology, we are able to breed high-quality disease-resistant Brassica crops in a more holistic, targeted and accurate way.
