Blackleg is a plant disease of potato caused by pectolytic bacteria that can result in stunting, wilting, chlorosis of leaves, necrosis of several tissues, a decline in yield, and at times the death of the potato plant. The term "blackleg" originates from the typical blackening and decay of the lower stem portion, or "leg", of the plant. [1]
Leptosphaeria maculans (anamorph Phoma lingam) is a fungal pathogen of the phylum Ascomycota that is the causal agent of blackleg disease on Brassica crops. Its genome has been sequenced, [2] and L. maculans is a well-studied model phytopathogenic fungus. Symptoms of blackleg generally include basal stem cankers, small grey lesions on leaves ...
This causes the cells to separate, a disease plant pathologists term bacterial soft rot. Specifically, it causes beet vascular necrosis and blackleg of potato and other vegetables (hence the name carotovora – "carrot-eater"), as well as slime flux on many different tree species. [ 2 ]

The host for Dickeya solani is the potato plant (Solanum tuberosum).Dickeya spp. can be the causal agents of soft rots and black leg. The symptoms that this bacteria causes can at times not be easily distinguished from the symptoms caused by Pectobacterium spp, since both pathogens induce a rotting of the plant tissue and black leg symptoms on the host.
Blackleg (disease), in sheep and cattle; Blackleg in rapeseed and other mustard-and-cabbage-family plants, caused by fungus Leptosphaeria maculans; Blackleg (potatoes), caused by Pectobacterium carotovorum; Blackleg (geraniums), caused by a form of the quasi-fungus Pythium; Scurvy, vitamin deficiency in primates and some other animals
The death toll from Legionnaires’ disease in Poland has risen to 16 with another 140 people infected in the southeastern region close to the border with Ukraine, health authorities said Wednesday.
Blackleg of potato symptoms showing darkened stem and leaf wilt on potato caused by the plant pathogen. Pectobacterium atrosepticum is a species of bacterium. It is a plant pathogen causing blackleg of potato. [1] Its type strain is CFBP 1526 T (=LMG 2386 T =NCPPB 549 T =ICMP 1526 T). [2] Its genome has been sequenced. [3]
