Tomato ringspot virus is one of the more insidious and difficult to control. Heat tolerance in tomato is regarded as a genetically controlled attribute of the plant because of significant genotype-environment interaction for this character (Rudich et al. Tomatenpflanzen und Temperatur . Identifying high-temperature stress-responsive (HSR) genes and breeding heat-tolerant varieties is an effective way to address this issue. Introduction. We showed that SlLC6D negatively regulates the tolerance of chilling stress, possibly by modulating the accumulation of ROS under chilling stress. Planting Vegetables. Analysis of low temperature tolerance in young wild-type and transgenic tomato plants. Cold stress leads to many changes of physiological indices, such as membrane permeability, free proline content, malondialdehyde (MDA) content, and chlorophyll content. Moreover, overexpression of three ethylene response transcription factors (ERF.C1/F4/F5) also improved HS tolerance in tomato. tolerance of tomato is determined by the ability of a plant to set fruits at high temperature. Selected References These references are in PubMed. Tomato (Lycopersicon esculentum cv. Materials and methods 2.1. It has been recorded recently in the northwestern border areas of China, posing a significant threat to tomato production. Plant Materials One hundred and forty six tomato accessions collected from around the world including one accession each of the wild species S. pimpinellifolium, S. pennellii and S. chilense were evaluated. The results demonstrate that gametophytic selection for low temperature tolerance of tomato pollen is determined, at least in part, by genes expressed in the haploid pollen. Explore. This work aimed to evaluate F 5 lines of tomato to fruit set and high temperature tolerance in two culture environments. 3A). High temperatures in the growing tomato have caused a reduction in fruit set and consequently productivity. Gardening. Our research provides insight for further study of the … The abiotic stresses become more complex under field conditions where more than one stressor typically coincide. Data represent the average of three independent biological replicates. This may not be the complete list of references from this article. Materials and Methods 2.1. 2. Blossom drop will occur in the spring if daytime temperatures are warm but night temps drop below 55 degrees F. (13 C.). Overexpression of SlLC6D in tomato was sensitive to low temperature. Therefore, heat stress tolerance screening is best complemented by multilocation field trials to test the response to various kinds of heat.
