概括

在 Allium tuberosum 中的多化会影响口腔护卫细胞 (GCs). 胃体的长度和宽度随着DNA含量的增加而增加,长度增长的速度更快,GCs发展出更多的叶绿体,增强了植物的适应性.

科学领域:

植物生物学植物生物学
遗传学是一个遗传学.
进化生物学是进化的生物学.

背景情况:

胃体特征 (密度,大小,叶绿体数) 用于区分多倍体和双倍体.
有限的研究存在于一个物种内的连续多体水平的口腔变异.
结核,通常是四平体,表现出多种多样性的平体水平,需要进一步研究.

研究的目的:

为了研究 Allium tuberosum 在不同 ploidy 级别的口腔变异.
为了分析护卫细胞 (GC) 密度,尺寸 (长度和宽度),以及与多倍化相关的叶绿体数量.
为了了解口腔特征如何在多化过程中演变.

主要方法:

鉴定出Allium tuberosum的种类,具有不同级别的化 (二化,三化,伪五化,伪六化).
量化了护卫细胞密度,大小 (长度和宽度) 和叶绿体数量.
胃部的特征在统计学上被分析到与性水平的关系.

主要成果:

没有发现ploidy水平和口腔密度之间的相关性; anisopolyploids显示的密度高于isopolyploids.
在ploidy水平和GC质细胞数量之间存在积极的关系.
随着形水平的增加,GC的长度和宽度都增加了,长度增长的速度大约是宽度的1.22倍.

结论:

护卫细胞的大小随着DNA含量增加而增加,但长度和宽度呈现不同的生长率.
在 Allium tuberosum 中的多化导致更长,更窄的胃体的演化,在护卫细胞中增加了叶绿体.
这些口腔修饰可能代表多体植物的适应性策略.

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Asexual Reproduction

Asexual Reproduction

Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Regulation of Transpiration by Stomata

Regulation of Transpiration by Stomata

During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Polytene Chromosomes

Polytene Chromosomes

Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...
