Natural hybridization between two strains, varieties, or species is a common phenomenon in both plants and animals. Although hybridization may skew established gene pools, it generates population diversity efficiently and sometimes results in the emergence of newly adapted genotypes. Cryptococcus neoformans, which causes the most frequent opportunistic fungal infection in immunocompromised host...

CAC1/RLF2 encodes the largest subunit of chromatin assembly factor I (CAF-I), a complex that assembles newly synthesized histones onto recently replicated DNA in vitro. In vivo, cac1/rlf2 mutants are defective in telomeric silencing and mislocalize Rap1p, a telomere-binding protein. Here, we report that in cells lacking CAF-I the silent mating loci are derepressed partially. MATa cac1 cells exh...

ABSTR;ZCT. Stigmaphyllon hispidum, a new species of Malpighiaceae, is described from Bahia, Brazil, where it was collected in a remnant of coastal forest, a vegetation type called Mata Atlantica. Its floral structure and adaxial laminar vesture are most similar to those of S. gayanum, an endemic of the region of Rio de Janeiro. The dense axial vesture, composed of simple basifixed hairs mixed w...
