Since Tomato yellow leaf curl virus (TYLCV) causes severe losses in tomato crops worldwide the search for genetic resources for breeding high-yielding, disease-resistant varieties remains challenging. We tested 25 tomato genotypes under field conditions to identify high-yielding disease-resistant genotypes. We identified several promising genotypes using advanced statistical methods, particularly genotype G13 which had a high yield of 8.8 kg per plant with 8.7 fruits per cluster and showed a low disease severity under high natural infection pressure. The genotypes G2, G3, G10, G11 showed moderate resistance, with disease severity ranging from...

The genetic basis of heterosis, which is widely exploited to increase crop yields, remains incompletely understood. Introgression lines created through interspecific hybridisation have been found to be useful for understanding the genetic basis of heterosis for economically important traits. Therefore, we used B. carinata-derived B. juncea introgression lines (ILs) to study the genetic basis of heterosis and identify genes associated with heterosis in elite hybrids. To assess the contribution of introgressed genomic segments in both homozygous and heterozy-gous states, ILs, introgression line hybrids (ILHs), and the B. juncea recipient...

Agricultural soil contamination with cadmium (Cd) has become an increasingly serious global issue, and cucumber (Cucumis sativus L.) is highly sensitive to Cd stress. Zinc/iron-regulated transporter-like proteins (ZIPs) are involved in the uptake and translocation of divalent cations. However, the functional roles of cucumber ZIP members in Cd transport remain poorly understood. In this study, we cloned and characterised CsZIP9, a ZIP gene from cucumber. Sequence analysis revealed that CsZIP9 contains eight transmembrane domains and shares high similarity with known Cd‑transporting ZIPs. Expression analysis showed...

Mustard (Brassica juncea) is an important oilseed and vegetable crop in China with high genetic diversity. Among its various forms, root and leaf mustard are two important vegetable forms. Cytoplasmic male sterility (CMS) provides an important strategy for exploiting heterosis in mustard. Ogu CMS is a widely utilised sterility type in Brassica species; however, studies on this type of male-sterile material in root and leaf mustard remain limited. To address this gap, this study was designed to (i) introgress the Ogu CMS cytoplasm from B. napus into leaf and root mustard via backcrossing, (ii) determine...

Yellow mosaic disease (YMD) in blackgram (Vigna mungo L. Hepper) is caused by whitefly-transmitted begomoviruses, particularly Mungbean yellow mosaic virus (MYMV) and Mungbean yellow mosaic India virus (MYMIV), which cause substantial economic losses across South and Southeast Asia. Exploitation of host plant resistance to develop resistant cultivars remains the most effective, economically feasible and sustainable management strategy. In northern India, MYMIV is a major viral disease affecting blackgram crop. The investigations were carried out to identify potential donors carrying genes imparting resistance against MYMIV-associated...
