Black Sigatoka
Black sigatoka is a leaf-spot disease of banana plants caused by the ascomycete fungus ''Mycosphaerella fijiensis'' (Morelet), also known as black leaf streak. It was discovered in 1963 and named for its similarities with yellow Sigatoka, which is caused by '' Mycosphaerella musicola'' (Mulder), which was itself named after the Sigatoka Valley in Fiji. In the same valley an outbreak of ''this'' disease reached epidemic proportions from 1912 to 1923. According to new terminology, the Sigatoka disease complex is a cluster of three closely related fungi: Black Sigatoka and its congeners Yellow Sigatoka ('' Ps. musae'') and eumusae leaf spot ('' Ps. eumusae''). Plants with leaves damaged by the disease may have up to 50% lower yield of fruit, and control can take up to 50 sprays a year. Life history ''M. fijiensis'' reproduces both sexually and asexually, and both conidia and ascospores are important in its dispersal. The conidia are mainly waterborne for short distances, whil ...

Pierre Marie Arthur Morelet
Pierre Marie Arthur Morelet (26 August 1809 – 9 October 1892) was a French natural history, naturalist, born in Lays, Doubs. He was a member of the commission to Algeria, primarily as a natural artist, drawing any natural findings. He collected specimens in the Canary Islands, Guatemala and Mexico. He had a particular interest in molluscs and was recognised as a leading expert in the field. Morelet married Noémie de Folin, sister of Léopold de Folin. Morelet died of natural causes in 1892, in Dijon. Taxa described Morelet described various taxa, including: * ''Cyclophorus horridulum'' (Morelet, 1882) – a species of land snail * ''Morelet's crocodile, Crocodylus moreletii'' (Morelet, 1850) – a crocodile Taxa named in his honour Taxa named in honour of Arthur Morelet include: * ''Agalychnis moreletii'' (André Marie Constant Duméril, A.M.C.

Strain (biology)
In biology, a strain is a genetic variant, a subtype or a culture within a biological species. Strains are often seen as inherently artificial concepts, characterized by a specific intent for genetic isolation. This is most easily observed in microbiology where strains are derived from a single cell colony and are typically quarantined by the physical constraints of a Petri dish. Strains are also commonly referred to within virology, botany, and with rodents used in experimental studies. Microbiology and virology It has been said that "there is no universally accepted definition for the terms 'strain', ' variant', and 'isolate' in the virology community, and most virologists simply copy the usage of terms from others". A strain is a genetic variant or subtype of a microorganism such as a bacterial strain or a specific strain of a virus, or fungus. For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. These flu strains are characterized ...

Department Of Agriculture And Fisheries
The Department of Primary Industries is the Queensland Government department responsible for developing Queensland's primary industries. The section known as Biosecurity Queensland is responsible for biosecurity matters within the state. The department was called the Department of Agriculture and Fisheries prior to November 2024. Functions Department of Agriculture and Fisheries provides expertise and support that increases primary industries productivity, expands markets and assists with adaption to change. It conducts research, policy advice, protects against pests and diseases, maintains animal welfare standards, as well as managing fisheries. History The first functions of the Department of Agriculture and Fisheries began in 1855 when a sheep scab inspector began work in the New South Wales colony of Moreton Bay. After Queensland's Separation, livestock diseases were addressed through regulations administered by the Stock Branch in the Queensland Colonial Secretary's O ...

Pests And Diseases Image Library
PESTS was an anonymous American activist group formed in 1986 to critique racism, tokenism, and exclusion in the art world. PESTS produced newsletters, posters, and other print material highlighting examples of discrimination in gallery representation (including lists of New York galleries representing only white artists) and museum exhibitions. PESTS also publicized events and exhibits featuring artists, scholars, and curators of color. While the members of PESTS are not known, members of the Guerilla Girls have stated that a Black member of Guerrilla Girls founded PESTS. PESTS also used similar tactics, including highlighting statistical data on posters with text graphics. Posters and flyers produced by PESTS included statements such as "THERE ARE AT LEAST 11,009* ARTISTS OF COLOR IN NEW YORK ¿WHY WON'T YOU SEE US?" and "¿WHAT IS TOKENISM (ANSWER) WHEN YOU'VE SEEN ONE ARTIST OF COLOR BUT THINK YOU'VE SEEN TEN."

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 μm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. ...

Commonwealth Mycological Institute
A commonwealth is a traditional English term for a political community founded for the common good. The noun "commonwealth", meaning "public welfare, general good or advantage", dates from the 15th century. Originally a phrase (the common-wealth or the common wealth – echoed in the modern synonym "public wealth"), it comes from the old meaning of "wealth", which is "well-being", and was deemed analogous to the Latin ''res publica''. The term literally meant "common well-being". In the 17th century, the definition of "commonwealth" expanded from its original sense of " public welfare" or " commonweal" to mean "a state in which the supreme power is vested in the people; a republic or democratic state". The term evolved to become a title to a number of political entities. Three countries – Australia, the Bahamas, and Dominica – have the official title "Commonwealth", as do four U.S. states and two U.S. territories. Since the early 20th century, the term has been used to name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stoma
In botany, a stoma (: stomata, from Greek language, Greek ''στόμα'', "mouth"), also called a stomate (: stomates), is a pore found in the Epidermis (botany), epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere. The pore is bordered by a pair of specialized Ground tissue#Parenchyma, parenchyma cells known as guard cells that regulate the size of the stomatal opening. The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture. Air, containing oxygen, which is used in cellular respiration, respiration, and carbon dioxide, which is used in photosynthesis, passes through stomata by gaseous diffusion. Water vapour diffuses through the stomata into the atmosphere as part of a process called transpiration. Stomata are present in the sporophyte generation of the v ...
