Porteresia coarctata is a species of grass in the family Poaceae, native to India, Sri Lanka, Bangladesh, and Myanmar. [3]

Porteresia coarctata is considered by some botanists to be the only species in the genus Porteresia. Other authors maintain instead that it should belong in the rice genus Oryza , [3] as Oryza coarctataRoxb. [4] It is a form of wild rice that grows in saline estuaries in Bangladesh and India and is harvested and eaten as a delicacy. [5] The plant is salt-tolerant, and is seen as a possibly important source of salt-tolerance genes for transfer to other rice species. [6] [7] It is closely related to Oryza australiensis . [8] The leaves of this species secrete salt through special microhair like structures that have three morphotypes, and a method to isolate these structures has been developed. [9] Porteresia coarctata is a perennial species that shows substantial underground rhizomatous growth. The rhizome tissues give out aerial shoots in a favourable season. [10]

Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.

Rice is the seed of the grass species Oryza sativa or less commonly Oryza glaberrima. The name wild rice is usually used for species of the genera Zizania and Porteresia, both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of Oryza.

Halotolerance is the adaptation of living organisms to conditions of high salinity. Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs. Halophiles are organisms that live in highly saline environments, and require the salinity to survive, while halotolerant organisms can grow under saline conditions, but do not require elevated concentrations of salt for growth. Halophytes are salt-tolerant higher plants. Halotolerant microorganisms are of considerable biotechnological interest.

<span class="mw-page-title-main">Halophyte</span> Salt -tolerant plant

A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes. An example of a halophyte is the salt marsh grass Spartina alterniflora. Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in the ehaloph database.

<span class="mw-page-title-main">Poaceae</span> Family of flowering plants commonly known as grasses

Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass.

<i>Oryza</i> Genus of plants

Oryza is a genus of plants in the grass family. It includes the major food crop rice. Members of the genus grow as tall, wetland grasses, growing to 1–2 metres (3–7 ft) tall; the genus includes both annual and perennial species.

<i>Oryza sativa</i> Species of plant

Oryza sativa, commonly known as Asian rice or indica rice, is the plant species most commonly referred to in English as rice. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.

<i>Distichlis palmeri</i> Species of flowering plant

Distichlis palmeri is an obligate emergent perennial rhizomatous dioecious halophytic C4 grass in the Poacea (Gramineae) family. D. palmeri is a saltwater marsh grass endemic to the tidal marshes of the northern part of The Gulf of California and Islands section of the Sonoran Desert. D.palmeri is not drought tolerant. It does withstand surface drying between supra tidal events because roots extend downward to more than 1 meter where coastal substrata is still moist.

<i>Pandanus amaryllifolius</i> Tropical plant in the screwpine genus

Pandanus amaryllifolius is a tropical plant in the Pandanus (screwpine) genus, which is commonly known as pandan. It has fragrant leaves which are used widely for flavouring in the cuisines of Southeast Asia and South Asia.

<i>Pancratium</i> (plant) Genus of flowering plants

Pancratium is a genus of African and Eurasian perennial, herbaceous and bulbous plants in the Amaryllis family, subfamily Amaryllidoideae

<i>Oryza barthii</i> Species of grass

Oryza barthii, also called Barth's rice, wild rice, or African wild rice, is a grass in the rice genus Oryza. It is an annual, erect to semierect grass. It has leaves with a short ligule, and panicles that are compact to open, rarely having secondary branching. The inflorescence structure are large spikelets, 7.7–12.3 millimetres long and 2.3–3.5 millimetres wide, with strong awns, usually red. The inflorescences have anthers 1.5–3 millimetres long.

<i>Oryza rufipogon</i> Species of grass

Oryza rufipogon, known as brownbeard rice, wild rice, and red rice, is a member of the genus Oryza.

<span class="mw-page-title-main">Crop wild relative</span> Wild plant closely related to a domesticated plant

A crop wild relative (CWR) is a wild plant closely related to a domesticated plant. It may be a wild ancestor of the domesticated (cultivated) plant or another closely related taxon.

Oryza nivara is a wild progenitor of the cultivated rice Oryza sativa. It is found growing in swampy areas, at edge of pond and tanks, beside streams, in ditches, in or around rice fields. Grows in shallow water up to 0.3 m, in seasonally dry and open habitats.

<i>Frankenia</i> Genus of flowering plants

Frankenia is the only genus in the Frankeniaceae family of flowering plants. Other genera have been recognized within the family, such as Anthobryum, Hypericopsis and Niederleinia, but molecular phylogenetic studies have consistently shown that they all belong inside Frankenia. Frankenia comprises about 70–80 species of shrubs, subshrubs and herbaceous plants, adapted to saline and dry environments throughout temperate and subtropical regions. A few species are in cultivation as ornamental plants.

Wild rice are four species of grasses forming the genus Zizania, and the grain that can be harvested from them.

Oryza punctata is an annual grass in the rice genus Oryza, also known as red rice, related to cultivated rice O. sativa. O. punctata forms clumps or tussocks from 50–120 cm tall. It is a native to tropical Africa and Madagascar but is also found in Thailand and other parts of Indochina. O. punctata is a weed species in commercial rice growing operations although it appears to be rare in its native range. O. punctata has an IUCN status of least concern. It is not generally eaten or used as fodder by farmers but there is some evidence that it has been used as such during periods of famine. Due to the importance of the crop varieties of rice globally, the evolution of the Oryza genus as a whole has been studied extensively. A lot of information about O. punctata has been elucidated as a secondary benefit to this commercial research. O. punctata evolved some 5 million years ago in the second of two rapid radiation events that occurred in the Oryza L. genus.

Altericroceibacterium indicum is a Gram-negative, rod-shaped and non-spore-forming bacterium from the genus Altericroceibacterium which has been isolated from the rhizosphere from the rice plant Porteresia coarctata in Pichavaram in India.

Mangrovibacter is a genus in the phylum Pseudomonadota (Bacteria). The name Mangrovibacter derives from:
New Latin noun mangrovum, mangrove; New Latin masculine gender noun, a rod; bacter, nominally meaning "a rod", but in effect meaning a bacterium, rod; New Latin masculine gender noun Mangrovibacter, mangrove rod.

Oryza latifolia, the broadleaf rice, is a widespread species of grass. It is native to wetter areas of Latin America and the Caribbean, and has been introduced to India, Bangladesh, Myanmar, Laos, and Vietnam. A facultative aquatic perennial, if flooded it can adapt by growing considerably taller.
