Pedotransfer functions are methods proposed with the objective of obtaining indirect information, with greater speed and ease to estimate various soil attributes. Thus, the objective of this work was to generate and obtain pedotransfer functions (PTFs) to predict the moisture retained at specific potentials in a Planosol under integration crop-livestock-forest system in the Agreste of Paraíba, three years after implementing the system. The research was conducted in an area located at the Experimental Station of the Paraíba Company of Research, Rural Extension and Land Regularization - EMPAER, in the district of Alagoinha, PB. The experimental design utilized was that of randomized blocks with 5 integration systems and 4 repetitions. The treatments were structured as 1) Gliricídia + Brachiaria decumbens (GS+BD); 2) Mimosa caesalpiniaefolia+ Brachiaria decumbens (MC+BD); Tabebuia alba + Brachiaria decumbens (TA+BD); 4) Zea mays + Brachiaria decumbens (ZM+BD); 5) Brachiaria decumbens (BD). Soil samples with undisturbed structure were collected in three layers (0.00-0.10; 0.10-0.20 and 0.20-0.30 m). Soil water retention was determined in the following matrix potentials: Psi m = -33 e -1,500 kPa. According to the results, it was possible to observe an increase in the available water content in all treatments, as a function of depth, and the soil granulometry was shown to be related to the increase of clay particles in the subsurface. |

Plasmopara viticola is the oomycete that causes downy mildew in grapevines. Varying levels of resistance to P. viticola across grape cultivars allowed quantitative trait loci to be identified. The Rpv3 locus is located at chromosome 18, in a region enriched in TIR-NBS-LRR genes, and the phenotype associated is a high hypersensitive response. In this work, we aimed to identify candidate genes associated with resistance to downy mildew on the Rpv3 locus and to evaluate their transcriptional profiles in a susceptible and a resistant grapevine cultivar after challenging with P. viticola. Candidate genes were identified by in silico functional enrichment tests. Many predicted genes associated with resistance to diseases were found at the Rpv3 locus. In total, seventeen genes were evaluated by RT-qPCR. Differences in the steady-state expression of these genes were observed between the two cultivars. Four genes were found to be expressed only in Villard Blanc, suggesting their association to the hypersensitivity reaction. Aiming to assist marker assisted-selection for downy mildew resistance, we show the efficient use of a set of SSR markers. Furthermore, from on a set of forty-one Rpv3-located SNPs, whose segregation was tested in the populations studied, the two segregating markers, Rpv3_15 and Rpv3_33, were considered efficient for downy mildew resistance identification. This study presents a genomic characterization of the Rpv3 locus, confirms its involvement in resistance against P. viticola infection and presents promising biotechnological tools for the selection of young resistant individuals.
