Septoria Lycopersici
''Septoria lycopersici'' is a fungal pathogen that is most commonly found infecting tomato The tomato is the edible berry of the plant ''Solanum lycopersicum'', commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. The Mexican Nahuatl word gave rise to the Spanish word ...es. It causes one of the most destructive diseases of tomatoes and attacks tomatoes during any stage of development.Douglas, S. M. (2008, June"Septoria Leaf Spot on Tomato"Missouri Botanical Garden (2017"Septoria Leaf Spot on Tomato" Host and symptoms ''Septoria lycopersici'' infects the tomato leaves via the stomata and also by direct penetration of epidermal cells. Symptoms generally include circular or angular lesions most commonly found on the older, lower leaves of the plant. The lesions are generally 2-5mm in diameter and have a greyish center with brown margins.Elmer, W. H., & Ferrandino, F. J. (1995). "Influence of spore density, lea ...

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomato
The tomato is the edible berry of the plant ''Solanum lycopersicum'', commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. The Mexican Nahuatl word gave rise to the Spanish word , from which the English word ''tomato'' derived. Its domestication and use as a cultivated food may have originated with the indigenous peoples of Mexico. The Aztecs used tomatoes in their cooking at the time of the Spanish conquest of the Aztec Empire, and after the Spanish encountered the tomato for the first time after their contact with the Aztecs, they brought the plant to Europe, in a widespread transfer of plants known as the Columbian exchange. From there, the tomato was introduced to other parts of the European-colonized world during the 16th century. Tomatoes are a significant source of umami flavor. They are consumed in diverse ways: raw or cooked, and in many dishes, sauces, salads, and drinks. While tomatoes are fruits†...

Anne Osbourn
Anne Elisabeth Osbourn is a professor of biology and group leader at the John Innes Centre, where she investigates plant natural product biosynthesis. She discovered that in the plant genome, the genes involved with biosynthesis organise in clusters. She is also a popular science communicator, poet and is the founder of thScience, Art and Writing (SAW)Initiative. She was elected a member of the National Academy of Sciences in 2022. Early life and education Osbourn grew up in West Yorkshire. Her parents both studied and lectured English literature and her father served in the army during World War II. She became interested in plants as a child and she attended Bingley Grammar School graduating in 1979. She earned a bachelor's degree in botany at Durham University in 1982. At this time, researchers worked out how to transform the ''Rhizobium'' nitrogen fixation genes into the bacterium ''Escherichia coli''. Osbourn moved to the University of Birmingham for her doctoral st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Septoria Leaf Spot Symptoms On Tomato Leaf (Septoria Lycopersici On Solanum Lycopersicum Leaf)
''Septoria'' are ascomycete pycnidia-producing fungi that cause numerous leaf spot diseases on field crops, forages and many vegetables including tomatoes which are known to contract '' Septoria musiva'' from nearby cottonwood trees, and is responsible for yield losses. The genus is widespread, and estimated to contain 1072 species. Pycnidia produce needle-like pycnidiospores. ''Septoria apiicola'' is the cause of late blight of celery. It is characterized by the production of conidia within pycnidia. The symptoms include chlorotic spots that turn brown and necrotic. ''Septoria apiicola'' can survive on seeds. Several species of passion flower are infected by several species of ''Septoria'', and a fungus, which has been going by the name '' Septoria passiflorae'' but which is probably an undescribed species, has been used to control the invasive ''Passiflora tarminiana ''Passiflora tarminiana'' (or banana passionfruit) is a species of passionfruit.
