Polyploid plants can arise spontaneously in nature by several mechanisms, including meiotic or mitotic failures, and fusion of unreduced (2n) gametes. [41] Both autopolyploids (e.g. potato [ …

Polyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and …

Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis. Polyploidy is common among plants and has been, in fact, a major source of speciation in the …

Polyploidy, or whole genome duplication (WGD), is a ubiquitous feature of plant species evolution, and all groups of green plants (Viridiplantae, hereafter referred to as plants) have one or more …

2019年11月1日 · Polyploidy is widely distributed in the plant kingdom. Genomic comparisons based on sequenced genomes indicate that all plant species evolved from one or more …

2005年1月1日 · Early influential reviews of polyploidy in plants include those of Müntzing (1936), Darlington (1937), Clausen et al. (1945), Löve and Löve (1949), and especially Stebbins …

2022年5月15日 · Polyploidy in plants. Polyploidy is very common in plants, especially in angiosperms. From 30% to 70% of today's angiosperms are thought to be polyploid. Species …

The flowering plants reflect a broad range of chromosome numbers (Weiss‐Schneeweiss & Schneeweiss, 2013) from 2n = 4 to 2n = 640. More importantly, surveys of levels of polyploidy …

2024年9月14日 · Polyploid organisms are characterized by having more than two sets of genomes. In many plant genera, such as Rosa (roses), species exhibit a range of ploidy levels …

2023年2月7日 · Scope: World-wide interest in how green plants have evolved under different conditions - whether in small, isolated populations, or globally - suggests that gaining further …
