The umbucajazeira is specie native to the Brazilian Northeast semiarid areas, which is economically explored based on the fruit. The fruit has a high agroindustrial potential, mainly for jam production. The aim of this study was to evaluate through sensorial analysis, two formulations of umbu-caja jams: a dietetic one with xylitol, used as an option for sub- stitution of the sugars, and a conventional one. The proportion of 50:50:0.5 (pulp/sugar/pectin or pulp/xylitol/pectin) was used for jam processing. The mixture was concentrated up to reach 65° Brix. The jams were evaluated by 50 non-trained tasters, through a hedonic scale of nine points, whereas the following attributes were used: appearance, color, flavor, aroma and texture. The results of the physical and physicochemical analysis showed that the characteris- tics of jams prepared with sucrose are close to the ones made with xylitol, except for the total sugars and the energetic value. The jams had pH values ranging between 2.37 and 2.92; titratable acidity varying between 0.56 and 0.78 g citric acid/100 g pulp; soluble solids ranging between 60.92° and 65.08° Brix, respectively. A tendency for yellow color was noticed by the color analysis. Jam diet had the highest scores for appearance (7.4 - 7.7). No significant differences (p > 0.05) were obtained to flavor and texture. The fruit of the umbucajazeira showed to be adequate for jam manufature since they had good sensorial acceptance. The use of xylitol was satisfactory for obtaining a product with jam charac- teristics similar to the conventional jam, but with lower energetic value.

ABSTRACT - The objective of this work was to determine whether the overexpression of the nuclear Rubisco large subunit (rbcL) improves the drought tolerance of the genetically modified (GM) BRSMG Curinga upland rice (Oryza sativa) cultivar. GM and non-genetically modified (NGM) plants of the same cultivar were compared under the two following water treatments: well watered (WW) and water deficit (WD). The performance of the agronomic traits of GM plants, including grain yield, was superior to that of NGM plants in both treatments. By quantitative polymerase chain reaction, GM plants show a significantly higher expression of the rbcL gene in both WW and WD, as well as a larger amount of abscisic acid. With the RNAseq analysis, almost three times more upregulated genes are identified in GM plants in stage 2 after water restriction, indicating a greater protection against water deficit. The higher expression of genes related to the protection of the cellular metabolism and a series of physiological alterations may be involved in the increase in the drought tolerance of GM rice plants overexpressing the rbcL gene.
RESUMO - O objetivo deste trabalho foi determinar se a superexpressão da grande subunidade nuclear da Rubisco (rbcL) aumenta a tolerância à seca da
cultivar geneticamente modificada (GM) BRSMG Curinga de arroz (Oryza sativa) de terras altas. Plantas GMs e não geneticamente modificadas (NGMs)
da mesma cultivar foram comparadas nos dois seguintes tratamentos de água: irrigação (WW) e déficit hídrico (WD). O desempenho dos caracteres
agronômicos das plantas GMs, incluindo a produção de grãos, foi superior ao das NGMs em ambos os tratamentos. Por reação em cadeia da polimerase
quantitativa, plantas GMs apresentam expressão significativamente maior do gene rbcL, tanto sob WW como sob WD, além de maior quantidade de ácido
abscísico. Com a análise de RNAseq, quase três vezes mais genes regulados positivamente são identificados nas plantas GMs no estágio 2 após restrição
hídrica, o que indica maior proteção contra o déficit hídrico. O aumento da expressão de genes relacionados à proteção do metabolismo celular e uma série de alterações fisiológicas podem estar envolvidos no aumento da tolerância à seca em plantas de arroz GMs que superexpressam o gene rbcL.
