Título: Effect of eCG on ovarian function of Curraleiro Pé-Duro cows submitted to a FTAI protocol. Autoria: TORTORELLA, R. D.; TEIXEIRA, H. C. A.; MODESTO, M. R; NEVES, J. P.; RAMOS, A. F. Conteúdo: The aim of this study was to determine the effect of equine chorionic gonadotropin (eCG) on follicular dynamics in a FTAI protocol. Twelve single cows with a mean body condition score (BCS) of 3 (1-5) were maintained in grazing conditions (Brachiaria decumbens) with ad libitum water and mineral supplementation.

Título: Different times of exogenous progesterone exposure associated or not with GnRH agonist on embryo production in ewes. Autoria: BRASIL, O. O.; MOREIRA, N. H.; SANTOS JÚNIOR, G.; SILVA, B. D. M.; RAMOS, A. F. Conteúdo: This study aimed to evaluate the effect of exogenous progesterone time exposure during supertimulation, with or without the addition of GnRH agonist on embryo yields in Santa Inês ewes. Forty-eight embryo donors were synchronized with intravaginal progesterone device (CIDR).

Título: The genomics of peanut and its wild relatives. Autoria: BERTIOLI, D. J.; VIDIGAL, B.; BERTIOLI, S. C. de M. L.; FROENICKE, L.; BEITEL, C.; NIELEN, S.; RATNAPARKHE, M.; BRASILEIRO, A. C. M.; GUIMARAES, P. M.; SCHWARZACHER, T.; MICHELMORE, R.; PATERSON, A. H.; HESLOP- HARISON, P.; ARAUJO, A. C. G. de Conteúdo: Cultivated peanut (A. hypogaea L. is a very important tropical oilseed, valued both for subsistence and as a cash crop. It is an allotetraploid of recent origin with an AB type genome (2n = 4x = 40) and has very low DNA polymorphism, a characteristic that has hampered genetic studies. The two sub-genomes diverged from a common ancestor about three and a half million years ago, more recently than the subgenomes of cotton or soya. The genome of peanut is estimated at about 2.8 Gb (only slightly smaller than the human genome) and has a high repetitive DNA content. During meiosis, peanut chromosomes pairing is almost entirely bivalent, an indication of genetic divergence of the A and B chromosomes. A significant divergence is also indicated by in situ hybridization analyses, which show that the repetitive contents of the A and B genomes are substantially different. Interestingly, evidence regarding the low copy fraction of the genome is converse: strong colinearity is observed between the A and B genome genetic maps, and indeed in many genome regions, gene order appears to have changed little over the last 55 million years. These diverging lines of evidence point to an intriguing question in[ the evolution of genome structure: how can the evolutionary flux of the structurally predominant repetitive DNA be reconciled with evolutionary conservation in low copy number DNA? Analysis of genomic sequences from the A and B genomes indicated that a large proportion of the sequence space is accounted for by relatively few transposons that have been active since the evolutionary divergence of the two subgenomes. The activity of these transposons has been a very significant driver of the erosion of A-B genome sequence similarity. Notably, this erosion is not evenly distributed; it is concentrated in intergenic regions.
