biodiversity-threat
Biodiversity threat refers to the escalating pressures—habitat destruction, climate change, invasive species, and overexploitation—that are driving unprecedented declines in the variety of life on Earth. For plant science, this is particularly critical because plants form the foundation of nearly all terrestrial ecosystems, and the loss of plant species can cascade through food webs, disrupt pollination networks, and eliminate sources of genetic diversity essential for agricultural resilience. Understanding and mitigating these threats is central to conservation botany and efforts to protect the vast, irreplaceable pharmacological and ecological value held within the world's flora.

Scientists identified a specific protein produced by an invasive plant pathogen that determines how severely it attacks different plant varieties. Understanding this protein explains why some plants are devastated while others survive the same infection.
A single conserved effector protein was identified as the key driver of genotype-dependent virulence differences across host plants
Transcriptomic analysis revealed the effector is expressed during active infection and is functionally required for full pathogen virulence
The effector's activity varies by host genotype, explaining why the same invasive pathogen causes severe disease in some plant varieties but not others
