Abstract:
Abstract The presence of salt in the soil is a major environmental factor that might reduce grapevine productivity. Excessive salt in the soil causes soil salinity, which in turn causes osmotic stress and toxicity to the grapevine’s root system. This can lead to stunted grapevine development, decreased harvests, and inferior fruit quality. Salinity can alter the physical characteristics of soil, making it less porous and less able to absorb water. This can amplify the negative impacts of salinity on grapevine development and harvest success. Numerous factors influence the severity of salinity’

Worldwide, virus infections in grapevines are of concern due to the potential for economic loss. Although the grape industry in Mexico is relatively small and focused mainly on the local market, production dates back to the time of the Spanish colonization. This manuscript discusses the findings on grapevine viruses in Mexico. Nine viruses have been identified in the last fifty years, including grapevine red blotch virus (GRBV), grapevine leafroll-associated virus 3 (GLRaV-3), grapevine fanleaf virus (GFLV), and grapevine virus A (GVA).

The grapevine (Vitis vinifera) is a major fruit crop of economic importance worldwide.

In this study, shotgun metagenomic sequencing was used to characterize the microbial communities associated with grapevine leaves in three commercial varieties, Cabernet Sauvignon, Garnacha, and Marselan, grown in the same biogeographical unit.

In this review, the current state of knowledge regarding grapevine SE as applied to these technologies is presented, with a focus on the benefits, challenges, and limitations of this method. The paper provides a comprehensive overview of the different steps involved in the grapevine SE process, including callus induction, maintenance of embryogenic cultures, and the production of plantlets.

Abstract:
Heavy metal toxicity is a major threat to the health of both humans and ecosystems. Toxic levels of heavy metals in food crops, such as grapes, can have devastating effects on plant health and the market value of the produce. Two important factors that may influence the prevalence of heavy metals in grapevines are seasonal change and farming practices. The objectives of this study were (i) to conduct a detailed pioneer screening of heavy metal levels in soils and grapevine leaf tissues in selected wine farms and (ii) to study the influence of season and farming on heavy metal levels in soils a

Hop stunt viroid (HSVd) is a major pathogen that affects grapevine health and causes substantial economic losses in grape cultivation. Many studies have been conducted to control grapevine diseases, but effective control methods after plant infections remain lacking. This study aimed to assess the antiviral potential of garlic extract, a natural substance that inhibits HSVds in grapevine plants after micropropagation. Garlic extract was diluted 1,000-fold and applied to grapevine plants, and its effect on HSVd accumulation was evaluated using reverse transcription polymerase chain reaction and
