Disease caused by Pepper yellow leaf curl virus (PepYLCV) is one of the greatest threats to pepper (Capsicum spp.) cultivation in the tropics and subtropics. Resistance to PepYLCV was previously identified in a few Capsicum accessions, but no resistance QTLs have been mapped. This study aimed to elucidate the genetics of PepYLCV resistance in C. annuum L. Augmented inoculation by the viruliferous whitefly Bemisia tabaci was used to evaluate parental lines and an F2 segregating population derived from a cross between resistant C. annuum line LP97 and susceptible C. annuum line ECW30R. Final evaluation was performed six weeks after inoculation using a standardized 5-point scale (0 = no symptoms to 4 = very severe symptoms). A high-density linkage map was constructed using genotyping-by-sequencing (GBS) to identify single-nucleotide polymorphism (SNP) markers associated with PepYLCV resistance in the F2 population. QTL analysis revealed three QTLs, peplcv-1, peplcv-7, and peplcv-12, on chromosomes P1, P7, and P12, respectively. Candidate genes associated with PepYLCV resistance in the QTL regions were inferred. In addition, single markers Chr7-LCV-7 and Chr12-LCV-12 derived from the QTLs were developed and validated in another F2 population and in commercial varieties. This work thus provides not only information for mapping PepYLCV resistance loci in pepper but also forms the basis for future molecular analysis of genes involved in PepYLCV resistance.

“…In India, tomato production is severely constrained by the disease tomato leaf curl virus, which occurs on a regular basis (ToLCVD). [7] Numerous tomato leaf curl virus (ToLCV) isolates cause ToLCVD, the most severe strain being the tomato leaf curl new Delhi virus in north India [8].…”

Tomato leaf curl disease (TLCD) is the most common viral disease in the tomato plant. It is caused by begomoviruses, which are viruses that cause plant development to be slowed. Many of the traditional disease management methods are still in use. They are, however, ineffective and out of date. Modern biotechnology is being used to detect illness in tomato plants as early as possible, thus reducing damage to the plants. Through genetic engineering, the spread of viruses may be controlled or prevented entirely. Here reviewed many methods for decreasing or eliminating the viral influence on crop growth through biotechnology and genomics. We also investigated the possibility of genetic engineering to reduce or remove the virus TLCD impact on tomato crop development.

“…The success of a microbial bio inoculant in the agricultural field is governed by a variety of factors, not only the microorganism's capacity to produce it [6][7][8][9][10][11][12]. Despite the fact that only a few species have been studied so far, our current knowledge of their capacities, ecological adaptations, many interactions, and possible positive features of bio-inoculants in plants is 2 restricted [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. The majority of medical research on the microbiome focuses on identifying and characterizing bacteria that produce eukaryotic bio-inoculants for use in human medicine.…”

Soil is a treasure trove of microbial variety, and bio-inoculants have the potential to improve the performance of horticultural crops under biotic and abiotic stress by boosting soil microbial diversity. Bio-inoculants are being developed to increase the diversity of soil microbes. The combined effects of bio-inoculants, on the other hand, result in the expansion of vegetation in the surrounding environment. Previous study on arbuscular mycorrhizal fungus has shown the existence of agronomic and biochemical characteristics in horticultural crop species (AMF). Through the development of enhanced technologies for the analysis of RNA or DNA from soil, we may acquire a deeper knowledge of the microbiological diversity and functions of the planet, which are difficult to find using traditional societal approaches. It is not possible to uncover a full database of purposeful genetics, which includes both soil microorganisms and deliberate genetics. This is true for almost every soil type or circumstance. As a result of this review, this study offers suggestions for the use of bio-inoculants, the benefits of doing so, regular research strategies, and long-term research directions.
