RNAi-mediated downregulation of AcCENH3 can induce in vivo haploids in onion (Allium cepa L.).

Haploid induction (HI) holds great promise in expediting the breeding process in onion, a biennial cross-pollinated crop. We used the CENH3-based genome elimination technique in producing a HI line in onion. Here, we downregulated AcCENH3 using the RNAi approach without complementation in five independent lines.

A glossy mutant in onion ( L.) shows decreased expression of wax biosynthesis genes.

Cuticular wax is a characteristic feature of land plants that provides protection against both biotic and abiotic stresses. In this study, a glossy mutant lacking an epicuticular wax layer was identified in the γ-irradiated M mutant population of the onion cultivar Bhima Super. The inheritance of the mutant's glossy phenotype was determined to be recessive and single locus.

Colonization of promotes resistance against in onion ( L.).

Plant-endophyte symbiosis influences plant defense and growth. is a root endophyte that promotes growth and induces tolerance against biotic and abiotic stress in plants. In this study, we examined the effect of colonization on herbivore () resistance of onion ( L.
