“…During ripening process, the increase of sugar content corresponds with the reduction of TA (Winsor et al, 1962). Similar study was shown in this study that showed during the ripening process, TSS was increasing and TA was decreased ( Figure 6).…”

Evidence of the functional role of the ethylene receptor genes SlETR4 and SlETR5 in ethylene signal transduction in tomato

Ethylene receptors are key factors for ethylene signal transduction. In tomato, six ethylene receptor genes (SlETR1-SlETR6) have been identified. Mutations in different ethylene receptor genes result in different phenotypes that are useful for elucidating the roles of each gene. In this study, we screened mutants of two ethylene receptor genes, SLETR4 and SLETR5, from a Micro-Tom mutant library generated by TILLING. We identified two ethylene receptor mutants with altered phenotypes and named them Sletr4-1 and Sletr5-1. Sletr4-1 has a mutation between the transmembrane and GAF domains, while Sletr5-1 has a mutation within the GAF domain. Sletr4-1 showed increased hypocotyl and root lengths, compared to those of wild type plants, under ethylene exposure. Moreover, the fruit shelf life of this mutant was extended, titratable acidity was increased and total soluble solids was decreased, suggesting a reduced ethylene sensitivity. In contrast, in the absence of exogenous ethylene, the hypocotyl and root lengths of Sletr5-1 were shorter than those of the wild type, and the fruit shelf life was shorter, suggesting that these mutants have increased ethylene sensitivity. Gene expression analysis showed that SlNR was up-regulated in the Sletr5-1 mutant line, in contrast to the down-regulation observed in the Sletr4-1 mutant line, while the down regulation of SlCTR1, SlEIN2, SlEIL1, SlEIL3, and SlERF.E4 was observed in Sletr4-1 mutant allele, suggesting that these two ethylene receptors have functional roles in ethylene signalling and demonstrating, for the first time, a function of the GAF domain of ethylene receptors. These results suggest that the Sletr4-1 and Sletr5-1 mutants are useful for elucidating the complex mechanisms of ethylene signalling through the analysis of ethylene receptors in tomato.

“…Total solids and total sugars increase progressively during development and maturation (WINSOR et al, 1962a;1962b). Generally, acidity in tomatoes increases during development and reaches a maximum at the breaker stage, then decreases with further ripening (DAVIES, 1966;STEVENS, 1972).…”

“…Number of fruit/plant ranged from 168 to 37.33. [41] noted this range from 171 to 19.02. Genotype TC0131-41-12-35-38-0-0, BINA Tomato-8, V1005584 and Walter showed highest green fruit girth; BINA Tomato-8, CL170-0-2-2-0, TC0131-41-12-35-38-0-0 and T2 had larger green fruit length; highest green fruit weight was found in genotype T8; highest red fruit girth and weight was observed in TC233-9-10-4-1-28-8; genotype ROBIN CVFS F1 RS (ˣ46) showed highest red fruit length.…”

The genetic variability for yield, its attributing, and fruit quality traits using 38 tomato genotypes was studied. High significant differences among the genotypes were found for all recorded traits. Phenotypic coefficient of variation was greater than genotypic coefficient of variation for all the traits indicating the presence of environmental influences. Most of the traits expressed moderate to high heritability. Plant height, number of seed/fruit, chlorophyll content in top leaf, red fruit weight, number of fruit/plant, soluble solid content in exocarp and endocarp of red fruit, titratable acidity of red fruit juice, lycopene content, beta-carotene and yield/plant had high heritability along with high genetic advance as percentage of the mean. Yield/plant exhibited a significant positive correlation with number of fruit/plant, number of flower/bunch, red fruit girth, red fruit length and red fruit weight. Path analysis revealed soluble solid content in endocarp of red fruit, number of fruit/plant, plant height, number of bunch/plant, number of flower/bunch, number of seed/fruit, green fruit length, red fruit girth, red fruit length, red fruit weight, lycopene and beta-carotene content had direct positive effect on yield/plant. Principal component analysis depicted first eight PCs with Eigen-value higher than one contributing 76.74% of total variability. Thirty-eight genotypes grouped into seven clusters where cluster II contains maximum genotypes. Based on the mean performance, genotypes Tm-131 and WOP-10 for yield and ascorbic acid content; Puli-25, VI005584 and Tm-2 for total soluble solids; VI-063607 and VI-0337183 for lycopene and beta-carotene content may be considered as superior genotypes which can be used as potential genetic resources for the development of nutritionally rich high-yielding tomato variety.
