    Funcționalitatea gametofitului mascul la descendenții plantelor de tomate reinfectate cu virusuri
    (CEP USM, 2024) Saltanovici, Tatiana; Andronic, Larisa; Antoci, Ludmila
    The article discusses the functionality of the male gametophyte in tomato offspring obtained from plants reinfected with Tobacco Mosaic Virus and Tomato Aspermy Virus. It was established that the plants from experimental variants showed specific responses associated with the change of the male gametophyte activity, that allows to the identification of resistant genotypes based on the established variability. According to the results of the ANOVA test, the variability of the pollen viability was primarily influenced by the genotype, which is important for the elucidation of the genetic basis of the reinfected genotypes and their descendants, as well as for breeding works. Genotypes that showed a high level of functionality of the male gametophyte under optimal and stressful conditions were highlighted, which allows their use in further research.

    IMPACTUL INFECȚIILOR VIRALE ASUPRA ACTIVITĂȚII GAMETOFITULUI MASCULIN DE TOMATE
    (CEP USM, 2023) Saltanovici, Tatiana; Andronic, Larisa; Antoci, Ludmila; Buldumac, Ana
    Reinfection of tomato genotypes with tobacco mosaic virus or tomato aspermia virus results in a change of plant pollen productivity and male gametophyte activity. Under the influence of infection, the specificity of the genotype response for a number of functional traits of the male gametophyte was revealed. Under conditions of primary infection and reinfection, the genotype was a determining factor in the variability of pollen viability, while the change in the size of pollen tubes was mainly determined by the appearance of viruses. As a result of the experiments, two varieties Venets and Rufina were selected for further research, combining a high level of pollen viability and productivity. They testify to a high reproductive capacity of varieties; the combination of these indicators can be used as a tool for the selection of valuable genotypes.
