We aimed to estimate transgenerational epigenetic variance for body weight using genealogical and phenotypic information in meat quails. Animals were individually weighted from 1 week after hatching, with weight records at 7, 14, 21, 28, 35 and 42 days of age (BW7, BW14, BW21, BW28, BW35 and BW42, respectively). Single-trait genetic analyses were performed using mixed models with random epigenetic effects. Variance components were estimated by the restricted maximum likelihood method. A grid search for values of autorecursive parameter (k) ranging from 0 to 0.5 was used in the variance component estimation. This parameter is directly related to the reset coefficient (m) and the epigenetic coefficient of transmissibility (1-m). The epigenetic effect was only significant for BW7. Direct heritability estimates for body weight ranged in magnitude (from 0.15 to 0.26), with the highest estimate for BW7. Epigenetic heritability was 0.10 for BW7, and close to zero for the other body weights. The inclusion of the epigenetic effect in the model helped to explain the residual and non-Mendelian variability of initial body weight in meat quails. |

ABSTRACT: Studies on the biodiversity of plants associated microorganisms play an important role in food production. Ficus-tree, Opuntia ficus-indica Mill, are cultivated in many nations worldwide intercropping with other cultures, like cowpea, Vigna unguiculata (L.) Walp. The objectives of this study were to isolate and determine the diversity of bacterial endophytes and rhizobacteria in cacti and their ability to solubilize phosphate, the nif presence, their ability to produce indole-acetic acid (IAA) and verify their efficacy to promote plant growth in cowpea plants. Bacteria were isolated from rhizospheric soils, from surface- sterilized stems and roots of plants collected in Brazil, in nitrogen- free medium, and identified through fatty acid analysis. Gram-negative bacteria comprised 63% of endophytic bacteria and 80% of rhizobacteria. Only 13% showed amplification of nifH gene. From the 68 bacterial strains, associated with cacti, 18% produced IAA, and the best results were observed in Agrobacterium radiobacter, Klebsiella trevisanii, Enterobacter agglomerans and Paracoccus denitrificans. Phosphate solubilization was observed in 6% of strains. None of the strains inoculated in cowpea plants promoted stem and foliar growth. Four percent of strains showed ability to increase the root dry matter compared to the control group (inoculated with a pool of indigenous semi-arid Rhizobium). |
