Abstract MYB TFs plays an important role in plant adaptation to abiotic stress, especially in response to salt stress. Preliminary research found that the stress resistance of the two melon varieties ‘M15’ and ‘baogua’ are quite different. To this end, we compared the transcriptomes of ‘M15’ and ‘baogua’. Transcriptome analysis found that the expression levels of 12 MYB transcription factors were significantly different between the two varieties.CmMYB1 gene was cloned from muskmelon (Cucumis melo L.), and the subcellular localization results showed that CmMYB1 was expressed in the cytoplasm and nucleus. Transform CmMYB1 gene into Arabidopsis thaliana, observe T3 phenotypes during the vegetative and reproductive growth periods.The results showed that the transgenic A. thaliana phenotype did not change significantly compared with the wild type . After treatment with 200 mM sodium chloride solution for 1 h and 3 h, the CmMYB1 expression increased significantly and began to decline after 6 h of salt stress, indicating that it functions in the early response to salt stress. These results provide a theoretical basis for the further study of the biological function of CmMYB1.

O experimento foi desenvolvido em casa de vegetação no município de Pombal, Paraíba PB, no período de abril a maio de 2015. Adotou-se o delineamento experimental inteiramente casualizado, em esquema fatorial 4 x 3 x 2 constituído de quatro níveis de salinidade da água de irrigação - CEa (0,3; 1,5; 3,0 e 4,5 dS m-1) e três substratos [S1= solo; S2= solo + composto orgânico (2:1); e S3 = solo + esterco bovino (2:1)], e duas variedades de melão (V1= Melão Gaúcho Casca de Carvalho; V2= Hales Best Jumbo), com quatro repetições e três plantas úteis por repetição. As plantas foram conduzidas em recipientes com capacidade de 0,5 dm3 durante 32 dias após a semeadura, quando foram avaliadas quanto ao crescimento e acúmulo de matéria seca. O crescimento e o acúmulo de matéria seca de ambas as variedades foram reduzidos com o aumento da salinidade da água de irrigação. O crescimento e acúmulo de massa seca da variedade Hales Best Jumbo no substrato constituído de solo com composto orgânico foi menos afetado pelo estresse salino. A variedade Gaúcho Casca de Carvalho é a mais sensível ao estresse salino independente do substrato utilizado. Palavras-chave: Cucumis melo L.; estresse salino, composto orgânico.  LOPES, M. A.

A.SALINE WATER AND SUBSTRATES ON INITIAL GROWTH IN MELON  2 ABSTRACT The aim was to study the production of melon seedlings for different substrates irrigated with saline water. The experiment was conducted in a greenhouse in the city of Pombal, Paraíba, PB, in the period April-May 2015. We adopted a completely randomized design in a factorial 4 x 3 x 2 design, consisting of four levels of irrigation water salinity (0.3, 1.5, 3.0 and 4.5 dS m-1) and three substrates [S1= ground; S2= soil + organic compound (2:1); and S3= soil + manure (2:1)] , and two varieties of melon (V1 = Gaúcho Casca de Carvalho; V2 = Hales Best Jumbo), with four replications and three plants per repetition. Plants were kept in containers with a capacity of 0.5 dm3 for 32 days after sowing, when they were evaluated for growth and accumulation of dry matter. Growth and dry matter accumulation of both varieties were reduced with increasing irrigation water salinity. The growth and accumulation of dry mass of the Hales Best Jumbo variety in the substrate composed of soil with organic compost was less affected by salt stress. The Gaúcho Casca de Carvalho variety is the most sensitive to salt stress regardless of the substrate used. Keywords: Cucumis melo L., salt stress, organic compound

Physiological And Biochemical

Melon (Cucumis melo L.) is a crop with important agronomic interest worldwide. Because of the increase of drought and salinity in many cultivation areas as a result of anthropogenic global warming, the obtention of varieties tolerant to these conditions is a major objective for agronomical improvement. The identification of the limiting factors for stress tolerance could help to define the objectives and the traits which could be improved by classical breeding or other techniques. With this objective, we have characterized, at the physiological and biochemical levels, two different cultivars (sensitive or tolerant) of two different melon varieties (Galia and Piel de Sapo) under controlled drought or salt stress. We have performed physiological measurements, a complete amino acid profile and we have determined the sodium, potassium and hormone concentrations. This has allowed us to determine that the distinctive general trait for salt tolerance in melon are the levels of phenylalanine, histidine, proline and the Na+/K+ ratio, while the distinctive traits for drought tolerance are the hydric potential, isoleucine, glycine, phenylalanine, tryptophan, serine, and asparagine. These could be useful markers for breeding strategies or to predict which varieties are likely perform better under drought or salt stress. Our study has also allowed us to identify which metabolites and physiological traits are differentially regulated upon salt and drought stress between different varieties.

Negative Effect

The performance of snake melon [Cucumis melo var. flexuosus (L.)] in organic farming was studied under high biotic and salt stress conditions. Soilborne diseases (mainly caused by Macrophomina phaseolina and Neocosmospora falciformis), combined with virus incidence [Watermelon mosaic virus (WMV), Zucchini yellow mosaic virus (ZYMV), and Tomato leaf curl New Delhi virus (ToLCNDV)] and Podosphaera xanthii attacks, reduced yield by more than 50%. Snake melon susceptibility to M. phaseolina and Monosporascus cannonballus was proved in pathogenicity tests, while it showed some degree of resistance to Neocosmospora keratoplastica and N. falciformis. On the contrary, salt stress had a minor impact, although a synergic effect was detected: yield losses caused by biotic stress increased dramatically when combined with salt stress. Under biotic stress, grafting onto the melon F1Pat81 and wild Cucumis rootstocks consistently reduced plant mortality in different agroecological conditions, with a better performance compared to classic Cucurbita commercial hybrids. Yield was even improved under saline conditions in grafted plants. A negative effect was detected, though, on consumer acceptability, especially with the use of Cucurbita rootstocks. Cucumis F1Pat81 rootstock minimized this side effect, which was probably related to changes in the profile of sugars, acids, and volatiles. Grafting affected sugars and organic acid contents, with this effect being more accentuated with the use of Cucurbita rootstocks than with Cucumis. In fact, the latter had a higher impact on the volatile organic compound profile than on sugar and acid profile, which may have resulted in a lower effect on consumer perception. The use of Cucumis rootstocks seems to be a strategy to enable organic farming production of snake melon targeted to high-quality markets in order to promote the cultivation of this neglected crop.
