Many annual plants, or plants grown in frost free areas, can suffer from damage when the air temperature drops below 40 degrees Fahrenheit (4 degrees Celsius). Tropical plants may begin to experience cold damage when the temperature is 42 to 48 °F (5 to 9 °C), symptoms include wilting of the top of the stems and/or leaves, and blackening or ...
Approximately 0.068% of all evaluated plant species are listed as extinct in the wild. The IUCN also lists one plant subspecies as extinct in the wild. This is a complete list of extinct in the wild plant species and subspecies as evaluated by the IUCN. All are vascular plants (tracheophytes).
Most bacteria associated with plants are saprotrophic and do no harm to the plant itself. However, a small number, around 100 known species, cause disease, especially in subtropical and tropical regions of the world. [15] [page needed] Most plant pathogenic bacteria are bacilli. Erwinia uses cell wall–degrading enzymes to cause soft rot.
Susceptibility to leaf spot disease can occur due to insufficient or excessive fertilising of plants. [8] Checking plants periodically for any signs and symptoms of disease is also good practice. [8] Avoiding overhead watering and increasing air circulation by pruning plants should be done to prevent humid conditions. [11]

Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild. As of September 2016, the International Union for Conservation of Nature (IUCN) lists 5430 Vulnerable (VU) plant species. [1] 25% of all evaluated plant species are listed as Vulnerable. The IUCN also lists 244 subspecies and 235 varieties as Vulnerable.
Bacterial wilt is a complex of diseases that occur in plants such as Cucurbitaceae and Solanaceae (tomato, common bean, [1] [2] etc.) and are caused by the pathogens Erwinia tracheiphila, a gram-negative bacterium, or Curtobacterium flaccumfaciens pv. flaccumfaciens, a gram-positive bacterium.
