Sunflower
The common sunflower (''Helianthus annuus'') is a species of large annual forb of the daisy family Asteraceae. The common sunflower is harvested for its edible oily seeds, which are often eaten as a snack food. They are also used in the production of cooking oil, as food for livestock, as bird food, and as plantings in domestic gardens for aesthetics. Wild plants are known for their multiple flower heads, whereas the domestic sunflower often possesses a single large flower head atop an unbranched stem. Description The plant has an erect rough-hairy stem, reaching typical heights of . The tallest sunflower on record achieved . Sunflower leaves are broad, coarsely toothed, rough and mostly alternate; those near the bottom are largest and commonly heart-shaped. Flower The plant flowers in summer. What is often called the " flower" of the sunflower is actually a "flower head" ( pseudanthium), wide, of numerous small individual five-petaled flowers (" florets"). The out ...

Sclerotium Bataticola
''Macrophomina phaseolina'' is a Botryosphaeriaceae plant pathogen fungus that causes damping off, seedling blight, collar rot, stem rot, charcoal rot, basal stem rot, and root rot on many plant species. Hosts, symptoms, and signs One of the most harmful seed and soil borne pathogens, ''Macrophomina phaseolina'' is a fungus that infects nearly 500 plant species in more than 100 families. The hosts include: peanut, cabbage, pepper, chickpea, soybean, sunflower, sweet potato, alfalfa, sesame, potato, sorghum, wheat, and corn, among others. The identification of isolates of ''M. phaseolina'' is usually based on morphology and efforts to divide the pathogen into subspecies, but because there are wide intraspecific variations in the phenotype of the isolates, these criteria are often not reliable. The failure to correctly detect and identify ''M. phaseolina'' using conventional culture-based morphological techniques has led scientists to develop nucleic acid-based molecular approa ...

Fusarium Oxysporum
''Fusarium oxysporum'' (Schlecht as emended by Snyder and Hansen), an ascomycete fungus, comprises all the species, varieties and forms recognized by Wollenweber and Reinking within an infrageneric grouping called section Elegans. It is part of the family Nectriaceae. Although their predominant role in native soils may be as harmless or even beneficial plant endophytes or soil saprophytes, many strains within the ''F. oxysporum'' complex are soil borne pathogens of plants, especially in agricultural settings. Taxonomy While the species, as defined by Snyder and Hansen, has been widely accepted for more than 50 years, more recent work indicates this taxon is actually a genetically heterogeneous polytypic morphospecies, whose strains represent some of the most abundant and widespread microbes of the global soil microflora. Genome The ' family of transposable elements was first discovered by Daboussi ''et al.'', 1992 in several ''formae speciales'' and Davière ''et al.'', 2001 ...

Gibberella Fujikuroi
''Gibberella fujikuroi'' is a fungal plant pathogen. It causes ''bakanae'' disease in rice seedlings. Another name is foolish seedling disease. It gets that name because the seeds can be infected, leading to disparate outcomes for the plant. There are not many diseases that initiate similar symptoms as bakanae. Hosts and symptoms ''Gibberella fujikuroi'' is most widely known for its disease producing capabilities in rice, but barley, millet, sugarcane and maize are also susceptible. In all infected plants, similar symptoms have been found, though rice has been most predominantly studied. The most telltale symptom of Bakanae is the tall, spindly look of the plant. This is a result of the gibberellins, or growth hormones, the fungus secretes. Infected plants are easy to pick out, then, as they often rise above the rest of the healthy plants with regularly secreted growth hormones. However, it is also possible that stunting may occur, along with Chlorosis of the leaves of the pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusarium Moniliforme
''Fusarium verticillioides'' is the most commonly reported fungal species infecting maize (''Zea mays''). ''Fusarium verticillioides'' is the accepted name of the species, which was also known as ''Fusarium moniliforme''. The species has also been described as mating population A of the ''Fusarium fujikuroi'' species complex (formally known as ''Gibberella fujikuroi'' species complex). ''F. verticllioides'' produces the mutagen In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer in ...ic chemical compound fusarin C. ''F. verticillioides'' produces a group of disease-causing mycotoxins— fumonisins—on infected kernels.

Nectria Haematococca
''Fusarium solani'' is a species complex of at least 26 closely related filamentous fungi in the division Ascomycota, family Nectriaceae. It is the anamorph of '' Nectria haematococca''. It is a common soil inhabiting mold. ''Fusarium solani'' is implicated in plant diseases as well as in serious human diseases such as fungal keratitis. History and taxonomy The genus ''Fusarium'' was described in 1809 by Link. In the 1930s, Wollenweber and Reinking organized the genus ''Fusarium'' into sections, including ''Martiella'' and ''Ventricosum,'' which were collapsed together by Snyder and Hansen in the 1940s to form a single species, ''Fusarium solani;'' one of nine ''Fusarium'' species they recognized based on morphological features. The current concept of ''F. solani'' is as a species complex consisting of multiple, closely related and morphologically poorly distinguishable, "cryptic" species with characteristic genetic differences.

Fusarium Equiseti
''Fusarium equiseti'' is a fungal species and plant pathogen on a varied range of crops. It is considered to be a weak pathogen on cereals and is occasionally found to be associated with 'Fusarium head blight' infected kernels. It is commonly found in tropical and sub-tropical areas. The species has been reported to be a causal organism of wilt in ''Capsicum chinense'' in Mexico in 2016. ''Fusarium equiseti'' is also one of the causal organisms for causing ''chilli wilt'' in Kashmir along with other fungi species; ''Fusarium oxysporum'' and ''Fusarium solani ''Fusarium solani'' is a species complex of at least 26 closely related filamentous fungi in the division Ascomycota, family Nectriaceae.
