| Abstract We cloned and characterized the full-length coding sequence of a small heat shock (sHSP) gene, PfHSP17.2, from Primula forrestii leaves following heat stress treatment. Homology and phylogenetic analysis suggested that PfHSP17.2 is a cytosolic class II sHSP, which was further supported by the cytosolic localization of transient expression of PfHSP17.2 fused with green fluorescent protein reporter. Expression analysis showed that PfHSP17.2 was highly inducible by heat stress in almost all the vegetative and generative tissues and was expressed under salt, cold, and oxidative stress conditions as well. Moreover, the expression of PfHSP17.2 in P. forrestii was detected in certain developmental growth stages. Transgenic Arabidopsis thaliana... |

| ABSTRACT The aim of this study was to evaluate the effect of salicylic acid (SA) application on pre-transplant acclimatization of native populations of tomato. SA is a growth regulator that modifies plant growth and development by inducing changes in cell processes, physiology and morphology. Five populations of native tomato were sown in polystyrene trays. Peat moss was used as substrate and plants were maintained at field capacity continuously. After emergence, seedlings were applied during three weeks with different concentration of SA (0.0, 0.01, 0.1, 0.5 and 1.0 μM). A completely random experimental design was used with five replications per treatment. The growth parameters evaluated were height, stem diameter, number of leaves, hypocotyl length,... |

| Resumo: Um dos fatores de maior preocupação na agricultura atual é a salinização do solo, especialmente a irrigada, sendo o manejo inadequado da irrigação e dos fertilizantes utilizados na atividade agrícola um dos principais determinantes responsáveis pelo aumento de áreas com solos degradados. No semiárido nordestino a evapotranspiração supera a precipitação e, por consequência, impossibilita a percolação da água através do perfil e, consequentemente, não acorre a lixiviação dos sais do solo. Diante das condições presentes na região Semiárida e dos problemas ocasionados pela salinização dos solos, o presente trabalho teve como objetivo avaliar emergência e crescimento inicial de feijão guandu em função de dois substratos e níveis de salinidade da água de... |

| The negative efects of lignocellulose-derived inhibitors such as acetic acid and furaldehydes on microbial metabolism constitute a signifcant drawback to the usage of biomass feedstocks for the production of fuels and chemicals. The yeast Pichia pastoris has shown a great biotechnological potential for producing heterologous proteins and renewable chemicals. Despite its relevance, the performance of P. pastoris in presence of lignocellulose-derived inhibitors remains unclear. In this work, our results show for the frst time the dose-dependent response of P. pastoris to acetic acid, furaldehydes (HMF and furfural), and sugarcane biomass hydrolysate, both at physiological and transcriptional levels. The yeast was able to grow in synthetic media with up to 6... |

| Soil-borne pathogens induce plant disease suppression by enriching members and activating functions in the rhizosphere microbiome. This is observed in disease suppressive soils, which show a remarkable ability to naturally suppress plant diseases caused by pathogens. Here, we selected two wheat genotypes, contrasting for Bipolaris sorokiniana resistance, to study how the pathogen affects the rhizosphere microbiome. As expected, the cultivation of the susceptible wheat led to a significant reduction in disease severity after five successive cultivation cycles. Conversely, the resistant genotype showed the opposite pattern, increasing disease severity over cycles. While bacterial families Chitinophagaceae, Anaerolineaceae and Nitrosomonadaceae are associated... |
