Fruit quality; Fruit shelf life; Plant breeding; Plant genetic resources; Tomato

The effects of wild germplasm on tomato fruit shelf life have not yet been completely evaluated. Three different genotypes of Lycopersicon esculentum (a cultivated variety, a homozygote for nor and a homozygote for rin), LA1385 of L. esculentum var. cerasiforme, LA722 of L. pimpinellifolium, and 10 diallel hybrids were assayed. Mean ... more

Combining ability; Heterosis; Line x tester analysis; Salinity; Seedlings; Tomato

We attempted to find the suitable parents for the development of tomato hybrids for high salt soils by exploiting combining ability, gene action and heterosis. Six salt-tolerant and three salt-intolerant genotypes, along with their 18 F1 crosses, were evaluated at seedling stage under 10 and 15 dS/m (NaCl) salinity stress, compared to the control level of salinity. The experiment was laid ... more

Cold stress; Enzyme activity; Lycopersicum esculentum L.; Real-time PCR; Superoxide dismutase; Tomato

The current study was designed to evaluate lipid peroxidation (via malondialdehyde) levels, the superoxide dismutase (SOD) gene expression profile, and SOD enzyme activity in tomato plants (Lycopersicum esculentum L.) subjected to different time periods of cold stress (control, 2, 4, 6, 8, and 10 days). Results revealed that maximum lipid peroxidation occurred in ... more

INH; Invertase gene families; RT-PCR; Tomato

Patterns of gene expression in the different types of sucrose metabolism in the tomato are highly variable and heritable. This genetic variation causes considerable functional differences. We examined the patterns of expression of invertase (Inv) gene families and an invertase inhibitor (INH) gene involved in elongating roots, hypocotyls, and fruit of the tomato (Lycopersicon ... more

Fruit shape; Gene expression; Genomic scanning; Tomato; YABBY gene

YABBY family genes play important roles in the development of leaf, flower, and fruit. The purpose of this research was to integrate all the YABBY genes and analyze the correlation between gene expression and fruit shape in tomato. Scanning of 24 genomes of sequenced species demonstrated that YABBY genes were very normal and stable in flowering plants except the seedless ... more

5-aminolevulinic acid; Aquaporin; Salinity stress; Tomato

The effects of exogenous 5-aminolevulinic acid (ALA) on photosynthesis, plant growth, and the expression of two aquaporin genes in tomato seedlings under control and salinity conditions were investigated. Exogenous ALA application significantly improved net photosynthetic rate (Pn), total chlorophyll content, and plant biomass accumulation of tomato seedlings under ... more

Cultivar identification; Cultivar identification diagram (CID); Genetic diversity analysis; Random amplified polymorphic DNA; Tomato

Cultivar identification diagrams (CIDs) provide a rapid and efficient approach for identifying cultivars based on random amplified polymorphic DNA (RAPD) markers. In this paper, 64 tomato cultivars were identified using a CID. Using RAPD profiles, clustering analysis was performed to analyze genetic diversity. The results showed that 8 RAPD primers could completely separate the 64 ... more
