Microbial diversity

Microbial diversity in coastal Casuarina equisetifolia forest and its potential in counteracting bacterial wilt infections


BACKGROUND


Casuarina wilt is a destructive soil-borne disease caused by Ralstonia solanacearum species complex (RSSC). Recent large-scale outbreaks of Casuarina wilt in the coastal regions of Guangdong Province, China, suggest that the originally resistant Casuarina clones become susceptible to RSSC infection. This study aimed to investigate the microbial diversity of environmental microorganisms and its potential in biocontrol of this devastating disease.

RESULTS


The results unveiled the dominant and common microbial species in Casuarina equisetifolia tree tissues, the rhizosphere soils and seawater in the vicinity of Casuarina equisetifolia forest belt. We also found a range of bacterial species with potent antimicrobial activities against Ralstonia pseudosolanacearum. Both the Casuarina endophyte A1-5, identified as Bacillus velezensis, and a combination biocontrol agent named CEP consisting of three mutually compatible soil isolates belonging to Citrobacter farmeri, Enterobacter aerogenes, and Pseudomonas mosselii, respectively, could effectively control the R. pseudosolanacearum infections on Casuarina and tomato. The active substance of strain A1-5 that inhibits the growth of R. pseudosolanacearum was purified and identified as surfactin C.

CONCLUSION


The findings unveiled the microbial diversity and their specific distributions in the Guangdong coastal Casuarina equisetifolia forest areas, and present useful clues and resources for developing new strategies to prevent and control the Casuarina bacterial wilt. © 2025 Society of Chemical Industry.

Genetics role in ovarian cancer

The Medical Minute: Genetics play big role in ovarian cancer In 2024, about 19,680 women in the United States will receive a new diagnosis of ovarian cancer and 12,740 women will die from the disease, said Dr. Shaina Bruce , a gynecologic oncologist at Penn State Cancer Institute . The median age of all patients who develop ovarian cancer is 63. Historically, women at increased risk for ovarian cancer are recommended to have their fallopian tubes and ovaries removed when they have completed having children. Taking that step to protect themselves comes at a heavy price ― surgical menopause. But Bruce said medical science is catching up with ovarian cancer. Studies could lead to new methods for preventative care and the surgery needed to lower risk may be easier than it once was. Below, during Gynecologic Cancer Awareness Month, Bruce discusses the disease and why acting to reduce your risk is worth it. What’s the connection between heredity and ovarian cancer? About 25% of all cases of ...

Migration in Population Genetics

  Migration in Population Genetics Migration in population genetics refers to the movement of individuals-and therefore their genes -between different populations of the same species. This gene flow alters allele frequencies, increasing genetic diversity within populations while reducing genetic differences between them. Migration can counteract the effects of genetic drift and inbreeding , introduce new alleles , and influence evolutionary processes such as adaptation and natural selection. The rate, direction, and scale of migration play a crucial role in shaping population structure, evolutionary potential, and long-term species survival, especially in fragmented habitats or changing environments.

Chromosomal Abnormalities

  Chromosomal Abnormalities Chromosome abnormalities refer to structural or numerical changes in chromosomes that can disrupt normal genetic function, leading to developmental disorders, congenital abnormalities, and various genetic diseases. These abnormalities may arise from errors in cell division, such as nondisjunction or chromosomal breakage, resulting in conditions like Down syndrome , Turner syndrome, Klinefelter syndrome , and various deletion or duplication syndromes. Understanding chromosome abnormalities is essential for genetic counseling, prenatal diagnosis, disease risk assessment, and research in cytogenetics and molecular genetics.
