| A review of our recent work on the cromosomal evolution of the Drosophila repleta species group is presented. Most studies have focused on the buzzatii species complex, a monophyletic set of 12 species which inhabit the deserts of South America and the West Indies. A statistical analysis of the length and breakpoint distribution of the 86 paracentric inversions observed in this complex has shown that inversion length is a selected trait. Rare inversions are usually small while evolutionary successful inversions, fixed and polymorphic, are predominantly of medium size. There is also a negative correlation between length and number of inversions per species. Finally, the distribution of inversion breakpoints along chromosome 2 is non-random, with chromosomal... |

| Trichoderma harzianum inducting resistance to Zymoseptoria tritici. Septoria tritici blotch is endemic in the wheat growing cultivated areas of Argentina, which impacts in the crop yield. One management strategy is to use biocontrol agents. The objective of this work was to determine the effectiveness of Trichoderma spp. isolated from soils of different growing regions, as antagonist and characterize the T. harzianum effect throughout the proteolytic activity of the serine protease in the wheat plant. To determine the antagonistic capacities of Trichoderma spp. against Zimoseptoria tritici, wheat plants were grown from seeds coated with each of the ninety isolated Trichoderma. Antagonism was assessed 21 days after inoculation by the capacity of each... |
