Article Abstract
spp. are important pathogens of citrus plants. Several species associated with species grown in China have been reported; however, the relative prevalences of individual species and the distributions of their genotypes among host species remain largely unknown. In this study, we conducted an extensive survey of species across 11 citrus-producing provinces in southern China. From fruits and leaves with black spots or black-spot-like symptoms, a total of 461 strains were isolated. Based on molecular (ITS, , , , LSU, and sequences) and morphological data, the strains were systematically identified as belonging to five species: , , , , and . To further understand intraspecific genetic diversity and relationships, strains of five species from different geographic and host sources were analyzed based on the multilocus sequence data. Our population genetic analyses revealed that all five species on citrus showed evidence for clonal dispersals within and among geographic regions. In addition, pathogenicity tests using representative strains showed that all five species can cause disease on the tested spp. We discuss the implications of our results for the control and management of Citrus Black Spot and related diseases.

Caliciopsis pinea is the ascomycete plant pathogen that causes caliciopsis canker disease on North American Pinus strobus (eastern white pine). Infections result in downgrading of lumber due to canker formation and overall loss of vigor in P. strobus, which is a critical cover species throughout its native range.

Background: Fish are the largest group of vertebrates. Studying the characteristics, functions, and interactions of different fish cells is important for understanding their roles in disease and evolution. However, most single cell RNA-seq studies in fish are restricted to a few specific organs, leaving a comprehensive cell landscape that aims to characterize the heterogeneity and connections among body-wide organs largely unexplored.

Background: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by oxidative stress and progressive motor neuron degeneration. This study evaluates the potential neuroprotective effects of caffeine in the Wobbler mouse, an established model of ALS.
Methods: Wobbler mice received caffeine supplementation (60 mg/kg/day) via drinking water, and key parameters, including muscle strength, NAD metabolism, oxidative stress, and motor neuron morphology, were assessed at critical disease stages.

Background: Soil salinization represents a critical global challenge to agricultural productivity, profoundly impacting crop yields and threatening food security. Plant salt-responsive is complex and dynamic, making it challenging to fully elucidate salt tolerance mechanism and leading to gaps in our understanding of how plants adapt to and mitigate salt stress.
Results: Here, we conduct high-resolution time-series transcriptomic and metabolomic profiling of the extremely salt-tolerant maize inbred line, HLZY, and the salt-sensitive elite line, JI853.

This study evaluated the significance of ten different pollen types-maize, Spanish broom, cattail, marshmallow, malva, sunflower, khejri, pomegranate, ice flower, and bee pollen-in influencing the development, reproduction, and population growth of E. scutalis. The aim was to enhance our understanding of the pollen spectrum acceptable to this predatory mite.
