Arundinaria is a genus of bamboo in the grass family the members of which are referred to generally as cane. [ 1 ] [ 2 ] Arundinaria is the only bamboo native to North America, with a native range from Maryland south to Florida and west to the southern Ohio Valley and Texas .
Saccharum officinarum is a large, strong-growing species of grass in the sugarcane genus. Its stout stalks are rich in sucrose , a disaccharide sugar which accumulates in the stalk internodes . It originated in New Guinea , [ 1 ] and is now cultivated in tropical and subtropical countries worldwide for the production of sugar , ethanol and ...
Sugarcane or sugar cane is a species of tall, perennial grass (in the genus Saccharum, tribe Andropogoneae) that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose , [ 1 ] which accumulates in the stalk internodes .
The spindle pole body (SPB) is the microtubule organizing center in yeast cells, functionally equivalent to the centrosome. Unlike the centrosome the SPB does not contain centrioles. The SPB organises the microtubule cytoskeleton which plays many roles in the cell. It is important for organising the spindle and thus in cell division.
Microtubule and tubulin metrics [1]. Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm [2] and have an inner diameter between 11 and 15 nm. [3]
Holocentricity has evolved at least 13 times independently in various green algae, protozoans, invertebrates, and different plant families. [15] Contrary to monocentric species where acentric fragments usually become lost during cell division, the breakage of holocentric chromosomes creates fragments with normal spindle fiber attachment sites. [16]
However, mostly it remains on plants of the genus Saccharum. Two to four months after the fungus has infected the plant, black whip-like structures, instead of a spindle leaf, emerge from the meristem, or growing point, of the plant. The developing whip is a mixture of plant tissue and fungal tissue.
3D rendering of centrioles showing the triplets. In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. [1] Centrioles are found in most eukaryotic cells, but are not present in conifers (), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.
