“…The rapid spread of the disease can be attributed to the pathogen's aggressive nature and the dispersal of sporangia by wind and water. Stag head infections are particularly damaging, as they not only cause structural deformities in the plant but also severely reduce the quality and quantity of seeds [46]. Efforts to combat white rust focus on early detection, genetic resistance, and improved agronomic practices.…”

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.

Silicon induces resistance in various crops against insect pests of diverse feeding guilds, including hemipterans, through upregulation of plant defense mechanisms along with maintenance of plant physiological processes. The present investigation to study the effect of silicon in the form of silicic acid (SA) against major sucking insect pests (Lipaphis erysimi and Bagrada hilaris) and natural enemies (Coccinella transversalis and Episyrphus balteatus) in rapeseed revealed that the foliar application of SA @ 0.4% thrice at 30, 40 and 50 days after sowing significantly reduced the colonization of L. erysimi as against non-significant effect on the population of B. hilaris. Three sprays of SA @ 0.4% significantly increased the population of C. transversalis without any significant effect on E. balteatus population. The silicon content of the rapeseed grains was also found to be significantly enhanced (0.32%) with 3 sprays of SA @ 0.4%.
