Leaf blight and spot caused by Stemphylium spp. Alternaria are the most common destructive tomato diseases in north-western Algeria. During 2018 growing seasons, more than 30% of samples collected from plants grown greenhouses or open fields were infected with Stemphylium. Initial symptoms small, multiple, irregular to oval, yellow leaf spots, which enlarged brown lesions later. In these lesion...

L-Asparagine uptake by Stemphylium botryosum is mediated by two distinct energy- and temperature-dependent transport systems. One permease is relatively specific for L-asparagine and L-glutamine and is present in nutrient-sufficient mycelium. The specific permease shows an optimum pH at 5.2, saturation kinetics (Km = 4.4 x 10(-4) M, Vmax = 1.1 mumol/g per min), competitive gradient of L-asparag...

Inheritance of resistance to Stemphylium solani and to its phytotoxin in cotton cultivars Leaf blight of cotton (Gossypium hirsutum) caused by Stemphylium solani occurs in several cotton growing areas of Brazil, and causes severe yield losses especially in the State of Paraná. The inheritance of resistance to S. solani and to its phytotoxin was investigated in three cotton cultivars. Crosses in...
