“…DLSC-1 showed complete resistance against all WR isolates. Two DH B. juncea mutant lines C66 and C69 exhibited a promising level of resistance against A. candida where C66 was shown completely resistant against white rust isolates (WRI) except susceptible to WRI-K isolate" [42].…”

Rape-seed mustard is an imperative edible oilseed crop which is adversely affected by different biotic stresses causing import of edible oils from abroad. The experiment was carried out for screening mustard genotypes based on disease indexing and putative role of diverse biochemical parameters in development of resistant against three major fungal diseases. A modified 0-9 scale was used for rating of disease indicators to calculate disease incident (DI). In disease indexing, mustard genotypes L-4, GSC-7 and PC-6 were considered as immune against Alternaria brassicae, Maya, L-4, China, GSL-1, GSC-7, PC-5, PC-6 and RP-9 were classified as immune against Albugo candida while L-4 and PC-5 were found immune against Erysiphe cruciferarum. The study of biochemical constituents demonstrated that these immune genotypes accumulated higher osmolytes content including free proline content and total phenol under diseased condition showing their tolerance ability against these pathogens. The tolerant genotypes also had lesser lipid peroxidation rate as indicated by malondialdehyde content analysis to induce lesser effect on total chlorophyll, amino acids, proteins and soluble sugars including reducing and non-reducing sugars. These identified genotypes have wider scope for further phyto-pathological studies and utilization in development of fungal resistance breeding.

“…There are 24 identified physiological races, with Race 2 (Ac2VRR) causing substantial annual losses in oilseed mustard in India, Canada, and Australia. Other races of A. candida specialize in different hosts, such as Race 1 (Ac1) that infects Raphanus sativus, Race 4 (Ac4) that affects Capsella bursa-pastoris, Race 5 (Ac5) that infects Sisymbrium officinale, and Race 6 (Ac6) that infects Rorippa islandica [22]. Race 7 (Ac7) is largely restricted to B. rapa but has been reported to affect some cultivars of B. napus and some genotypes of B. juncea.…”

White rust, caused by the oomycete pathogen Albugo candida, poses a significant threat to mustard cultivation, leading to reduced yields and compromised oilseed quality. This study explores the genomic and molecular mechanisms underlying the host-pathogen interaction in B. juncea and outlines resistance strategies to counter white rust. While it is the predominant oilseed Brassica species in India, it is cultivated on a smaller scale in China and Australia. Due to its drought-hardy nature, B. juncea is being bred for canola-quality traits to expand its cultivation into lower rainfall regions. Research has demonstrated that resistance to white rust in B. juncea is regulated by a single dominant gene, and numerous lines, such as 'Bio-YSR', 'BEC-144', and 'JM-1', exhibit this trait. Comparative proteomic studies identified 19 proteins with significant expression changes between resistant and susceptible varieties. One key protein, PR-5, a thaumatin-like protein, has been linked to the resistance mechanism. Recent advances in genomic research, including the use of AFLPs, intron polymorphic markers, and SSRs, have enabled breeders to track and validate resistance traits. Enrichment of NLR repertoire, over-expression of R genes, silencing of avirulent and disease susceptibility genes through RNA interference and CRSPR-Cas are technologies which have been successfully applied against pathogen-resistance mechanism. These findings pave the way for genetic-based approaches to develop white rust-resistant B. juncea cultivars, providing a sustainable strategy to protect oilseed production in diverse climatic conditions. This study's insights contribute to a deeper understanding of host-pathogen interactions and offer promising solutions to mitigate the impact of white rust on mustard crops.
