“…The better performance of these hybrids may be associated with their vitality and resistance to diseases, thus contributing to their higher productivity, since the period of this cultivation, summer-autumn, has a higher rainfall and higher susceptibility to diseases, such as leaf diseases, that unsupported plants can accelerate ripening and, Revista de Agricultura Neotropical, Cassilândia-MS, v. 7, n. 3, p. 20-28, jul./set. 2020. consequently, increase the number of unviable fruits for fresh consumption (Quezado-Duval et al, 2014) (Table 3).…”

The cultivation of hybrid tomatoes, intended for fresh consumption, with a determined growth habit, and without support, is an alternative that has a lower production cost. The research aimed to evaluate the productivity and economic viability of different tomato genotypes, with a determinate and indeterminate growth habit. The experimental design was in completely randomized blocks. Ten hybrids and a variety were grown in 2016, and nine hybrids, and a variety in 2018, with a spacing of 0.5 meters between plants. Harvests were carried out in four periods in 2016, at 72, 82, 97, and 105 days after transplanting (DAT); and in 2018 at 81, 87, 97, and 111 DAT. After harvesting, the gross value of production and profit were quantified. The hybrids that obtained the highest production per plant in 2016 were Gabrielle (6,010 kg), with support; Thaise (5.529 kg); and N901 (5.003 kg). In 2018, Dominador and Thaise hybrids had the highest production, with 4.109 and 3.961 kg per plant, respectively. The gross value of tomato production in 2016 was higher than in 2018 for all hybrids and variety, except for Dominador hybrid. Hybrids with a determined growth habit and conducted without support are a profitable alternative to produce tomatoes intended for fresh consumption, especially the hybrid Gabrielle, which had the highest production. The economic viability of hybrids grown without support is superior to all hybrids with support.

“…A more sustainable strategy for pest management is the development of pest resistant/tolerant plant cultivars. Strategies for the development of commercial cultivars resistant/tolerant to whitefly-transmitted viruses have been developed, for example, the transgenic common bean cultivar BRS FC401 RMD, which is resistant to BGMV ( Bonfim et al, 2007 ; Faria et al, 2016 ; Souza et al, 2016 ) and the tomato cultivar BRS Sena, tolerant to Bemogoviruses ( Quezado-Duval et al, 2014 ). However, considering the plasticity of the “virus transmission ability” phenotype of B. tabaci , as well as its high adaptation to a wide range of environments and hosts, plant breeding for resistance to plant virus may contribute to the virus disease management, but not to the management of other viruses transmitted by this insect vector.…”

Whitefly-tolerant transgenic common bean (Phaseolus vulgaris) line

et al. 2022

Common bean (Phaseolus vulgaris L.) is a staple food in Brazil with both nutritional and socioeconomic importance. As an orphan crop, it has not received as much research attention as the commodity crops. Crop losses are strongly related to virus diseases transmitted by the whitefly Bemisia tabaci, one of the most important agricultural pests in the world. The main method of managing whitefly-transmitted viruses has been the application of insecticides to reduce vector populations. Compared to chemical vector control, a more sustainable strategy for managing insect-borne viruses is the development of resistant/tolerant cultivars. RNA interference has been applied to develop plant lines resistant to the whitefly in other species, such as tomato, lettuce and tobacco. Still, no whitefly-resistant plant has been made commercially available to date. Common bean is a recalcitrant species to in vitro regeneration; therefore, stable genetic transformation of this plant has been achieved only at low frequencies (<1%) using particle bombardment. In the present work, two transgenic common bean lines were obtained with an intron-hairpin construct to induce post-transcriptional gene silencing against the B. tabaci vATPase (Bt-vATPase) gene, with stable expression of siRNA. Northern blot analysis revealed the presence of bands of expected size for siRNA in leaf samples of the line Bt-22.5, while in the other line (11.5), the amount of siRNA produced was significantly smaller. Bioassays were conducted with both lines, but only the line Bt-22.5 was associated with significant mortality of adult insects (97% when insects were fed on detached leaves and 59% on the whole plant). The expression of the Bt-vATPase gene was 50% lower (p < 0.05) in insects that fed on the transgenic line Bt-22.5, when compared to non-transgenic controls. The transgenic line did not affect the virus transmission ability of the insects. Moreover, no effect was observed on the reproduction of non-target organisms, such as the black aphid Aphis craccivora, the leafminer Liriomyza sp. and the whitefly parasitoid Encarsia formosa. The results presented here serve as a basis for the development of whitefly-tolerant transgenic elite common bean cultivars, with potential to contribute to the management of the whitefly and virus diseases.

Residual polysaccharides from fungi reduce the bacterial spot in tomato plants

et al. 2018

View full text Add to dashboard Cite

Polysaccharides from fungal wastes were partially characterized and evaluated for their protective effects against bacterial spot caused by Xanthomonas gardneri on four tomato cultivars: Santa Cruz Kada, Natália, BRS Sena and Forty. The polysaccharides were extracted from spent mushroom substrate of Pleurotus ostreatus, residual brewery yeast (Saccharomyces cerevisiae), and basidiocarps discarded from Lentinula edodes production. These polysaccharides were characterized for total carbohydrates, phenolics and proteins content, pH, scatter intensity, conductivity, Zeta potential, DPPH scavenging assay and infrared spectroscopy. The effects of time interval between treatment and inoculation (4 or 7 days) and polysaccharide concentrations (0.5 or 1.5 mg.mL-1) were assessed for disease severity using a susceptible tomato cultivar. The polysaccharide action mode was investigated by determining the activity of peroxidases and phenylalanine ammonialyase and by quantifying flavonoids and total phenolics in the plants
