Breeding of a low pyruvate-producing sake yeast by isolation of a mutant resistant to ethyl alpha-transcyanocinnamate, an inhibitor of mitochondrial pyruvate transport. | LitMetric
Pyruvate is the key substance controlling the formation of diacetyl, acetaldehyde, and acetate during alcoholic fermentation. Here we report the breeding of a low pyruvate-producing sake yeast by isolation of a mutant resistant to ethyl alpha-transcyanocinnamate, an inhibitor of mitochondrial pyruvate transport. Mitochondrial function was involved in resistance to this substance and in the production of pyruvate by the mutants.
We have identified a unique genetic locus for seed shattering in Italian ryegrass that has an exceedingly large effect and shows partial dominance for reduced seed shattering. Genetic improvement of seed retention in forage grasses can contribute to improving their commercial seed production. The objective of this study was to identify the genetic loci responsible for seed shattering in Italian ryegrass (Lolium multiflorum Lam.

Tembusu virus (TMUV) is a significant pathogen that poses a considerable threat to the waterfowl farming industry in China and is classified into three distinct genetic clusters. In 2024, a suspected outbreak of TMUV infection was reported at a goose farm in Guangdong Province, China. A strain of TMUV, designated GDE19-2024, was successfully isolated using chicken embryos.
Avian pathogenic (APEC) is one of the major causes of poultry morbidity worldwide, severely reducing egg production and embryo hatchability in laying hens. Hainan Wenchang chicken is an important poultry breed in Hainan, China, and its culture has been affected by APEC for a long time. In this study, in order to investigate the causes of low hatchability and a large number of weak chicks during the breeding of Wenchang chicken, a total of 130 strains of APEC were isolated from 591 chicken embryo samples collected from five large-scale farms of Wenchang chicken in Hainan area.
More than 2 000 yeast strains isolated from 1 200 samples mostly collected from Tibet and Yunnan provinces in China were identified as 462 species according to the internal transcribed spacer including the 5.8S rDNA (ITS) and the D1/D2 domains of the large subunit rDNA (LSU) sequence analyses. Among them, 70 new basidiomycetous yeast species were proposed based on the multi-locus phylogenetic analyses including the D1/D2 domains, the ITS, the small subunit rDNA (SSU), the largest subunit of RNA polymerase II (), the second largest subunit of RNA polymerase II () and translation elongation factor 1-α (), as well as the phenotypic comparisons.
Limiting the level of piglet losses before weaning is a growing demand from producers and society to improve the welfare and health of sows and piglets. In particular, perinatal mortality, which can be defined as the complete development allowing survival at birth, is mostly due to reduced piglet maturity that occurs at the end of gestation. Fetal growth and maturation depend on a fine balance between the nutrient requirements for optimal fetal growth and the maternal nutrient requirements.
