Two cases of leucism in Southern Lapwing Vanellus chilensis (Molina, 1782) in the south of Brazil. [PDF]
Biotemas, 2009 We present the reports of two leucistic individuals of the Southern Lapwing Vanellus chilensis obtained in the rural area of the municipality of Novo Hamburgo, Rio Grande do Sul, and at the Botanic Garden of Curitiba, Paraná, south of Brazil.

Advanced Science, Volume 12, Issue 22, June 12, 2025.We developed a citramalate‐derived pathway for 2‐methylbutyric acid production in E. coli mono‐culture and consortia. The optimized consortium, using 2‐keto‐3‐methylvalerate as a node, achieved 1817.03 ± 103.73 mg L−1 2‐methylbutyric acid, a 28‐fold increase from the initial strain, with a yield of 0.091 g/g glucose.

Journal of Fauna BiodiversityPlumage aberrations in birds, particularly leucism, are rare but significant phenomena that offer insights into avian genetics and ecology. Leucism, distinct from albinism, results in partial or total loss of melanin in feathers without affecting eye ...

First Record of Leucism in the GenusPeromyscus(Mammalia: Rodentia)
Western North American Naturalist, 2014 ABSTRACT. Leucism is a partial hypopigmentary congenital disorder previously recorded in several species of mammals. This abnormal coloration is unusual in the wild. In August 2013, in Baja California, Mexico, we collected 2 Peromyscus fraterculus (one female and one male) exhibiting leucism.

Microbial Biotechnology, Volume 18, Issue 6, June 2025.In this study, RNA‐seq was employed to investigate the temporal transcriptional response of C. glutamicum ATCC 13032 to external H2O2 at 720 mM (2.45% w/w). The results reveal significant changes in gene expression across multiple pathways, including peroxide scavenging, central metabolism, sulphur and iron metabolism, amino acid biosynthesis, and DNA ...

FIRST RECORD OF LEUCISM IN Coendou spinosus (RODENTIA, ERETHIZONTIDAE)
Oecologia AustralisLeucism is a pigmentary anomaly that results in a white or yellowish fur in mammals. Here we report the first observation of a leucistic individual of Coendou spinosus (Rodentia; Erethizontidae) in a mangrove area during a wildlife monitoring program in the industrial district of Rio de Janeiro municipality.

Plant Biotechnology Journal, Volume 23, Issue 5, Page 1535-1547, May 2025.Summary Vitamin E (VE) is essential for plants and animals. Rapeseed oil is rich in α‐tocopherol (α‐T), which is the most bioactive form of VE in human body. This study demonstrated that VE in rapeseed seeds was mainly controlled by embryo genotype through incomplete diallel hybridization.

Primer registro de leucismo en un tapir de tierras bajas silvestre Tapirus terrestris (Linnaeus, 1758) en la región de la Orinoquia colombiana [PDF]
Polymorphic phenotypes, like leucism, occur due to genetic mutations and are rare in wild populations. Leucism, marked by partial or complete pigmentation loss but normal eye color, is often linked to genetic drift and inbreeding in fragmented habitats ...
