TL;DR: In this article, it was shown that the anatase phase can be obtained independently on any previous or further treatment of the synthesized powder, such as hydrothermal or heat treatment, providing a new, simple, quick, and inexpensive route to synthesize anatase powders.

TL;DR: Five strains of a novel yeast species isolated from rotting wood samples collected in an Amazonian forest site in the state of Roraima, northern Brazil showed that this species belongs to the Scheffersomyces clade and is related to Candida coipomoensis, Candida lignicola and Candida queiroziae.
Abstract: Five strains of a novel yeast species were isolated from rotting wood samples collected in an Amazonian forest site in the state of Roraima, northern Brazil. The sequences of the D1/D2 domains of the large subunit of the rRNA gene showed that this species belongs to the Scheffersomyces clade and is related to Candida coipomoensis, Candida lignicola and Candida queiroziae. The novel species Candida amazonensis sp. nov. is proposed to accommodate these isolates. The type strain of C. amazonensis sp. nov. is UFMG-HMD-26.3(T) ( = CBS 12363(T) = NRRL Y-48762(T)).

TL;DR: O trabalho avaliou-se a heranca da cor do fruto de um mutante natural da cv.
Abstract: Neste trabalho avaliou-se a heranca da cor do fruto de um mutante natural da cv. Santa Clara, por meio da analise das geracoes F1 e segregantes, obtidas mediante cruzamento entre plantas da cv. Santa Clara normal e o mutante amarelo. A caracterizacao das plantas normais, mutantes e F1 foi feita com base na analise quantitativa dos pigmentos carotenoides e clorofila em flores, folhas e frutos verdes e maduros. Plantas F1 e provenientes do retrocruzamento com o progenitor normal apresentaram 100% de frutos vermelhos. A semelhanca entre os F1 reciprocos mostra que ha ausencia de heranca materna para as caracteristicas avaliadas. Em geracoes segregantes, as frequencias observadas foram compativeis com heranca monogenica pelo teste qui-quadrado, com dominância completa para o gene que confere cor vermelha. Os frutos amarelos apresentaram teores reduzidos de b-caroteno e licopeno, enquanto o hibrido apresentou teores intermediarios desses carotenoides quando comparados com o genotipo normal. Os niveis de clorofila em frutos verde-maduros e maduros mutantes foram menores que nos frutos normais, evidenciando o papel dos carotenoides sobre a fotoprotecao da clorofila. A concentracao de clorofila e carotenoides, em folhas e flores, nao foi afetada pela mutacao.
