Alternaria linicola is a fungal plant pathogen, [1] that affects linseed plants ( Linum usitatissimum ). [2] [3]
Flax, also known as common flax or linseed, is a flowering plant, Linum usitatissimum, in the family Linaceae. It is cultivated as a food and fiber crop in regions of the world with temperate climates. Textiles made from flax are known in English as linen and are traditionally used for bed sheets, underclothes, and table linen. Its oil is known as linseed oil. In addition to referring to the plant, the word "flax" may refer to the unspun fibers of the flax plant. The plant species is known only as a cultivated plant and appears to have been domesticated just once from the wild species Linum bienne, called pale flax. The plants called "flax" in New Zealand are, by contrast, members of the genus Phormium.
Linseed oil, also known as flaxseed oil or flax oil, is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant. The oil is obtained by pressing, sometimes followed by solvent extraction.
The founder crops or primary domesticates are a group of flowering plants that were domesticated by early farming communities in Southwest Asia and went on to form the basis of agricultural economies across Eurasia. As originally defined by Daniel Zohary and Maria Hopf, they consisted of three cereals, four pulses, and flax. Subsequent research has indicated that many other species could be considered founder crops. These species were amongst the first domesticated plants in the world.
Linola is the trademark name of solin, cultivated forms of flax bred for producing linseed oil with a low alpha-linolenic acid content. Linola was developed in the early 1990s by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). It was developed and released in Australia in 1992 and first commercially grown in 1994. Australian Linola varieties are named after Australian lakes.
In plant biology, Vavilovian mimicry is a form of mimicry in plants where a weed evolves to share one or more characteristics with a domesticated plant through generations of artificial selection. It is named after Nikolai Vavilov, a prominent Russian plant geneticist. Selection against the weed may occur by killing a young or adult weed, separating its seeds from those of the crop (winnowing), or both. This has been done manually since Neolithic times, and in more recent years by agricultural machinery.
Alternaria is a genus of Deuteromycetes fungi. All species are known as major plant pathogens. They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma. They are present in the human mycobiome and readily cause opportunistic infections in immunocompromised people such as AIDS patients.
Mycosphaerella linicola is a fungal plant pathogen.
The genus Canna is susceptible to certain plant viruses, which may result in spotted or streaked leaves, in a mild form, but can finally result in stunted growth and twisted and distorted blooms and foliage. Known species of virus are:
Alternaria dianthi, sometimes known as carnation blight, is a fungal pathogen of the genus Dianthus. Alternaria dianthi infections begin as small circular or ovular spots on leaves and stems, which can be red, purple, brown, yellow or gray.
Alternaria helianthi is a fungal plant pathogen causing a disease in sunflowers known as Alternaria blight of sunflower.
Cacao swollen shoot virus (CSSV) is a plant pathogenic virus of the family Caulimoviridae that primarily infects cacao trees. It decreases cacao yield within the first year of infection, and usually kills the tree within a few years. Symptoms vary by strain, but leaf discoloration, stem/root swelling, and die-back generally occur. The virus is transmitted from tree to tree by mealybug vectors. It was first discovered in Ghana in 1936, and is currently endemic in Togo, Ghana and Nigeria. Over 200 million trees have already been claimed by this disease, which has prompted Ghana to launch the most ambitious and costly eradication effort of any country in the world against a viral plant disease.

Olinalá is a city and seat of the municipality of Olinalá, in the state of Guerrero, south-western Mexico. It is well known throughout the country for its crafts, called Lacas de Olinalá.
Clostridium sporogenes is a species of Gram-positive bacteria that belongs to the genus Clostridium. Like other strains of Clostridium, it is an anaerobic, rod-shaped bacterium that produces oval, subterminal endospores and is commonly found in soil. Unlike Clostridium botulinum, it does not produce the botulinum neurotoxins. In colonized animals, it has a mutualistic rather than pathogenic interaction with the host.
Rhizophagus irregularis is an arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture. Rhizophagus irregularis is also commonly used in scientific studies of the effects of arbuscular mycorrhizal fungi on plant and soil improvement. Until 2001, the species was known and widely marketed as Glomus intraradices, but molecular analysis of ribosomal DNA led to the reclassification of all arbuscular fungi from Zygomycota phylum to the Glomeromycota phylum.
Cochylis epilinana is a species of moth of the family Tortricidae. It is found in most of Europe, Asia Minor, Israel and northern Syria.
Argyrotaenia loxonephes is a species of moth of the family Tortricidae. It is found in Argentina.
Alternaria tenuissima is a saprophytic fungus and opportunistic plant pathogen. It is cosmopolitan in distribution, and can colonize a wide range of plant hosts. Colonies of A. tenuissima produce chains on agar growth media. The fungus often forms concentric ring patterns on infected plant leaves. This species produces the allergen Alt a 1, one of the most important outdoor seasonal fungal allergens associated with allergy and asthma provocation. In rare circumstances, this species is also known to infect immunosuppressed humans and animals.
The production of flax and other oilseed crops peak in the temperate climates of the middle mountain and hill farming regions in Nepal. Flax matures in approximately 90 to 125 days and develops most rapidly under the cool, short season of growing. The middle hill region of the Lamjung district exemplifies an ideal climate for flax production experiencing consistently cool temperatures for most of the year. The shallow rooting system makes the plant especially susceptible to drought and excess moisture in the soil but easier to harvest. Most cash crops are grown in the hill regions of Nepal as this is where two-thirds of the subsistence farmers reside, who need to produce just enough food to feed themselves and their families.
