“…SlMYB12 mutation leads to premature termination of the amino acid sequence and structural changes, resulting in a colorless epidermis phenotype in tomato fruits ( Veerappan et al, 2016 ). Compared with yellow tomatoes, ISOPENTENYL DIPHOSPHATE ISOMERASE 1 ( IDI1 ) is a cytoplasmic enzyme involved in the biosynthesis of isoprenoids, including cholesterols, that inserts a single T base into exon 6 in apricot tomatoes, resulting in a decrease in carotenoid content and yellow pericarp ( Nakamura et al, 2015 ; Shin et al, 2019 ; Chattopadhyay et al, 2021 ). Several genes and their mutant alleles related to carotenoid biosynthesis have been identified and characterized in tomato fruit.…”

The quality of vegetables is facing new demands in terms of diversity and nutritional health. Given the improvements in living standards and the quality of consumed products, consumers are looking for vegetable products that maintain their nutrition, taste, and visual qualities. These requirements are directing scientists to focus on vegetable quality in breeding research. Thus, in recent years, research on vegetable quality has been widely carried out, and many applications have been developed via gene manipulation. In general, vegetable quality traits can be divided into three parts. First, commodity quality, which is most related to the commerciality of plants, refers to the appearance of the product. The second is flavor quality, which usually represents the texture and flavor of vegetables. Third, nutritional quality mainly refers to the contents of nutrients and health ingredients such as soluble solids (sugar), vitamin C, and minerals needed by humans. With biotechnological development, researchers can use gene manipulation technologies, such as molecular markers, transgenes and gene editing to improve the quality of vegetables. This review attempts to summarize recent studies on major vegetable crops species, with Brassicaceae, Solanaceae, and Cucurbitaceae as examples, to analyze the present situation of vegetable quality with the development of modern agriculture.

“…With prepped items, the extended shelf-life is most evident; this, along with the consumer's convenience of use, renders a MAP pack an appealing type of product display. MAP packs also cut down on the amount of water vapor wasted by the produce (Chattopadhyay et al, 2021;Floros & Matsos, 2005).…”

Fresh vegetables and fruits need oxygen (O 2 ) to carry out their metabolic activities, particularly respiration. The procedure where the actively respiring commodity is sealed in film packages made of polymer to change the CO 2 and O 2 levels of concentration inside the package environment required to increase shelf-life and preserve freshness is referred to as modified atmosphere packaging (MAP). To affect the product's metabolism being packaged or the activity of organisms that cause degradation to extend the time of preservation, it is frequently desired to create an environment high in CO 2 and low in O 2 . MAP changes the environment and increases moisture preservation that has a bigger impact on quality preservation. Moreover, packing separates the product from the surrounding environment, assisting in the creation of circumstances that, if not hygienic, at the very least minimize exposure to infections and pollutants, as well as physiological damage. MAP is a dynamic mechanism that occurs concurrently throughout permeation and respiration. As a result, MAP design necessitates the assessment of the product's intrinsic features, such as film permeability, optimal O 2 and CO 2 gas concentrations, and respiration rate. The goal of MAP design is to specify parameters that will provide the greatest feasible environment within the package for increasing the product's shelf-life in the quickest possible time. This is accomplished by synchronizing the packed produce's respiration rate with O2 and CO2 gas penetration rate through the film. The current study contains a detailed discussion of all of these elements of MAP.

“…Nonetheless, taking into account the pleiotropic nature of hp2, it is reasonable that other metabolites, in addition to flavonols, may be involved in the improved thermotolerance of pollen. To test this hypothesis for secondary metabolites, for example, various pigmentation mutants of tomato could be utilized (Chattopadhyay et al, 2021). The importance of primary metabolites such as starch and soluble sugars for pollen thermotolerance was demonstrated by Firon et al (2006); however, no alterations in soluble sugars were detected in fruits of the hp2 mutant (Bino et al, 2005).…”

Climate change has created an environment where heat stress conditions are becoming more frequent as temperatures continue to raise in crop production areas around the world. This situation leads to decreased crop production due to plant sensitivity to heat stress. Reproductive success is critically dependent on plants’ ability to produce functional pollen grains, which are the most thermo-sensitive tissue. Flavonols are plant secondary metabolites known for their potent antioxidative activity, essential for male fertility in several species including tomato, and implicated in heat stress tolerance. Since flavonols are highly abundant in fruits of the tomato high pigment 2 (hp2) mutant, we tested the level of flavonols in pollen of this mutant, under the hypothesis that increased accumulation of flavonols would render pollen more tolerant to heat stress. Indeed, pollen from two alleles of the hp2 mutant was found to have flavonols levels increased by 18 and 280% compared with wild-type (WT) under moderate chronic heat stress (MCHS) conditions. This mutant produced on average 7.8-fold higher levels of viable pollen and displayed better germination competence under heat stress conditions. The percentage of fully seeded fruits and the number of seeds per fruit were maintained in the mutant under heat stress conditions while decreased in wild-type plants. Our results strongly suggest that increased concentrations of pollen flavonols enhance pollen thermotolerance and reproductive success under heat stress conditions. Thus, the high flavonols trait may help frame the model for improving crop resilience to heat stress.
