摘要

壶菌病是由壶菌引起的一种重要的新兴疾病,导致全球两栖动物数量下降。Bd的表型变异,如游动孢子囊的大小和游动孢子的产生,可能与分离株之间的致病性和对温度的适应差异有关。在墨西哥的许多地区都发现了Bd,但其表型变异性和与致病性的关系仍未被探索。在这里,我们研究了Bd的表型特征,如生长速度、携带能力、游动孢子产量和游动孢子囊大小,这些分离物代表了Bd全球panzotic谱系中不同亚系的10个分离物,这些分离物来自墨西哥不同的温度制度。我们发现菌株之间的表型差异很大,其生长速度和游动孢子囊大小受各自地点环境温度的影响。其他性状,如承载能力和游动孢子产量,没有显示出与环境温度相关的明确模式。我们的研究结果提供了对墨西哥Bd表型变异性的见解,并强调了病原体-环境相互作用的复杂性,表明了当地适应性。

Influence of environmental temperature on the phenotypic variation of Batrachochytrium dendrobatidis isolates from Mexico
Chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd), is a major emerging disease contributing to the global decline of amphibians. Phenotypic variations in Bd, such as zoosporangia size and zoospore production, may be linked to differences in pathogenicity among isolates and adaptation to temperatures. Bd has been detected in various regions in Mexico, but its phenotypic variability and relationship to pathogenicity remain unexplored. Here, we examine phenotypic characteristics of Bd such as the growth rate, carrying capacity, zoospore production, and zoosporangia size of ten Bd isolates representing different sublineages within the Bd Global Panzootic Lineage, collected from diverse temperature regimes in Mexico. We found high phenotypic variability between isolates, with growth rate and zoosporangia size influenced by the environmental temperature of their respective sites. Other traits, such as carrying capacity and zoospore production, did not show clear patterns related to environmental temperature. Our findings provide insights into the phenotypic variability of Bd in Mexico and highlight the complexity of pathogen-environment interactions suggesting local adaptations.

期刊介绍: Fungal Genetics and Biology, formerly known as Experimental Mycology, publishes experimental investigations of fungi and their traditional allies that relate structure and function to growth, reproduction, morphogenesis, and differentiation. This journal especially welcomes studies of gene organization and expression and of developmental processes at the cellular, subcellular, and molecular levels. The journal also includes suitable experimental inquiries into fungal cytology, biochemistry, physiology, genetics, and phylogeny. Fungal Genetics and Biology publishes basic research conducted by mycologists, cell biologists, biochemists, geneticists, and molecular biologists. Research Areas include: • Biochemistry • Cytology • Developmental biology • Evolutionary biology • Genetics • Molecular biology • Phylogeny • Physiology.
