The study of tolerance mechanisms for drought stress in soybean is fundamental to the understanding and development of tolerant varieties. Using in silico analysis, four marker genes involved in the classical ABA-dependent and ABA-independent pathways of drought response were identified in the Glycine max genome in the present work. The expression profiles of the marker genes ERD1-like, GmaxRD20A-like, GmaxRD22-like and GmaxRD29B-like were investigated by qPCR in root samples of drought sensitive and tolerant soybean cultivars (BR 16 and Embrapa 48, respectively), submitted to water deficit conditions in hydroponic and pot-based systems. Among the four putative soybean homologs to Arabidopsis genes investigated herein, onlyGmaxRD29B-like was not regulated by water deficit stress. Distinct expression profiles and different induction levels were observed among the genes, as well as between the two drought-inducing systems. Our results showed contrasting gene expression responses for the GmaxRD20A-like and GmaxRD22-like genes. GmaxRD20A-like was highly induced by continuous drought acclimating conditions, whereas GmaxRD22-like responses decreased after abrupt water deprivation. GmaxERD1-like showed a different expression profile for the cultivars in each system. Conversely, GmaxRD20A-like and GmaxRD22-like genes exhibited similar expression levels in tolerant plants in both systems. |

In grape production, cover crops play a key role in soil protection and nutrient cycling. Thus, since grapevine requirements for P are low, adequate management of cover crops may provide sufficient P for growth. This paper evaluates the effect of black oats, as a cover plant, on the P solubilization in rock phosphate and its availability to the vine cultivated in succession. To test this hypothesis, we evaluated the plants growth parameters and P uptake in grapevines grown in succession to black oats in pots in a greenhouse experiment. The results showed that the soil sterilization decreased P availability to black oats, but not to grapevine. The soil fertilization with rock phosphate increased the P accumulation in oat and grapevine plants, although no further effect was observed from the use the cover crop. The plant height and dry mass contents were higher for grapevine in soils fertilized with rock phosphate and covered with black oats.
