Qualidade de frutos de tomate ‘giuliana’ tratados com produtos de efeitos fisiológicos

The present work evaluated the effect of strobilurins, boscalid, plant growth regulators and vegetal extracts on the physico-chemical quality of tomato fruits (Solanum lycopersicum L.), hybrid Giuliana. The fruits from each treatment were selected and separated in 4 repetitions: control, pyraclostrobin, boscalid, pyraclostrobin + boscalid, IBA + GA(3) + kinetin, GA(4+7) + benzylaminopurine and vegetal extract. The first application was carried out at 30 days after transplant and the following at every 15 days. The evaluations were: weight loss, titratable acidity (TA), soluble solids (SS), SS/TA relation, pH, ascorbic acid content, texture, total soluble sugars (TSS), activity of pectin methyl esterase (PME) and polygalacturonase (PG). The SS content, responsible for fruit flavor, varied accordingly to the treatment, being highest for GA(4+7) + benzylaminopurine and lowest for the control. The same occurred regarding the SS/AT relation. The fruits were kept on the shelf for 9 days, at room temperature, being that at the end of this period several treatments still presented fruit in optimal consumption conditions, notably the boscalid treatment, which presented lowest weight loss, followed by pyraclostrobin. Therefore, it can be concluded that the application of the treatments did not modify the values for pH, AT and AST of the fruits. The highest PME activity was observed for the treatments with boscalid and the mixture of boscalid and pyraclostrobin, while the lowest PG activity occurred in the control and the pyraclostrobin treatment, indicating that some products accelerated the process of demethylation of pectins by PME, facilitating the action of PG.

Caracterização molecular do gene que codifica a TCTP (Translationally Controlled Tumor Protein) em tomate (Solanum lycopersicum cv. Santa Clara)

The gene encoding TCTP (Translationally Controlled Tumour Protein) is present in all eukaryotes and its product is involved in various cellular processes. Although well characterized in mammals, there are only few works available in the literature related to the analysis of this protein in plants. In this present work, the expression of the gene encoding TCTP was analyzed in different organs/tissues of tomato plants (Solanum lycopersicum cv. Santa Clara). A quantification performed by RT-qPCR revealed the presence of TCTP transcript in all tissues/organs analyzed, with the highest expression level found in leaves. With the exception of fruits in intermediate stage of maturation, for which a small increase on the expression was detected, there was minimal variation in the relative expression of TCTP in other organ/tissues. In parallel, the effects of the constitutive expression of TCTP were investigated using transgenic tobacco lines able to overexpress this protein at different levels (T1, T2 and T3). Seedlings of these lines, and of a non-transgenic control line, were grown in MS culture medium for 21 days. At the end of this period, the length of roots and leaves was taken and the seedlings were photographed. According to Tukey's test, the analysis of the mean root length revealed a significant difference between T1 and T3 lines when compared to the control, although the same was not observed for the T2 line. For leaves, according to Kruskal-Wallis test, there was a statistical difference between the averages of leaf growth obtained for the different lines evaluated. According to these results, we can conclude that TCTP shows an ubiquitous expression in tomato plants, with the highest expression detected in leaves, and also that its overexpression promoted a higher root and leaf development in two of three transgenic tobacco lines tested
