Abstract: The first stet for applying superovulation is to know the responsiveness of the ewe to different estrous synchronous protocol duration and possible implications on embryo yield. On the other hand for nonsurgical embryo recovery (NSER) a well consolidated protocol should be tested and, in Morada Nova ewes, successful non-surgical uterine access was reported (Fonseca et al., 2019. Reprod Fertil Devel, 31:17-26). In this context, the objective of this study was to evaluate the efficiency different synchronous estrus induction and NSER as additional tool to evaluate the results these protocols in pluriparous Morada Nova ewes. A total of 18 pluriparous sheep were divided into three treatment groups with 6 (T6, n=6), 9 (T9, n=6) and 12 (T12, n=6) days of 60 mg of medroxyprogesterone acetate (Progespon®, Zoetis, Campinas, São Paulo, Brazil). The NSER mean duration was 27.6±1.4 min, with recovery of 99.8% of injected fluid and embryo recovery rate of 62.97% (17/27). These preliminary results indicated that all protocols provided similar results and that NSER can be successfully performed and used as additional toll in synchronous estrous induced Morada Nova ewes independently from the duration of progestogen regimen to assure that viable embryos can be produced by ewes subjected by these protocols.

Soybean (Glycine max (L.) Merr.) genotype PI 416937 has been identified as expressing a ?slow-wilting? phenotype in the field and this has been traced to a low hydraulic conductance in its leaves. The transpiration rate of de-rooted shoots of this genotype has been found to be insensitive to the aquaporin inhibitor silver nitrate compared to elite cultivars which are silver nitrate sensitive. These results indicated that PI 416937 might have a unique aquaporin population. The objective of this study was to determine if QTLs could be identified that are associated with the lack of sensitivity in PI 416937 to silver. To identify the genomic locations and genetic bases of this trait, a recombinant inbred line population was derived from a mating between PI 416937 and the cultivar ?Benning?. The RILs were all phenotyped for their response to the silver inhibitor and the results were subjected to a QTL analysis. Four QTL were identified as putatively associated with the silver response (qSV). These QTL explaine from 17.7 to 24.7% of the phenotypic variation with qSV_Gm12 explaining the greatest amount of phenotypic variation. The qSV_Gm03 and qSV_Gm10 QTL inherited their positive alleles from PI 416937, while qSV_Gm05 and qSV_Gm12 inherited their favorable alleles from Benning. Co-localized silver nitrate response QTL with other morpho?physiological traits could help to explain soybean plant's ability to tolerate water-deficit stress. |
