ref: 植物和動物具有相同的分子生長機制
植物和動物具有相同的分子生長機制
美國Purdue大學的研究人員報道說，一種新發現的植物蛋白復合體似乎能開啟植物的生長機器。這一發現為人們研究植物和動物的發育提供了一個重要的工具箱。
肌動蛋白絲是細胞生長所必須的。這種蛋白復合體能觸發一種製造肌動蛋白絲途徑中的分子間的交流。與這個過程有關的生化反應的知識將最終促使研究人員創造出能更好地保護自己的植物。這項研究的結果公佈在2月的The Plant Cell雜誌上。
通過對肌動蛋白絲形成途徑的瞭解，人們能夠使植物細胞以不同的方式生長或改變細胞對外界刺激物的反應方式。
這種新發現的蛋白復合體就是ARP2/3（Actin Related Protein2/3，肌動蛋白相關蛋白2/3）。它是一種控制肌動蛋白絲形成的機器，而肌動蛋白絲對細胞的生長和運動很重要。肌動蛋白絲組織細胞內部並使它生長，而且它們還決定細胞中一定結構的所處位置以及植物對重力和光線的反應方式。

amyloid
Amyloid
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Amyloids are various types of insoluble fibrous protein aggregations sharing specific traits when examined microscopically. The name amyloid comes from the early mistaken identification of the substance as starch (amylum in Latin), based on crude iodine-staining techniques. For a period, the scientific community debated whether or not amyloid deposits were fatty deposits or carbohydrate deposits until it was finally resolved that it was neither, but rather a deposition of proteinaceous mass.
Amyloid deposits are extracellular, thioflavin-positive, and exhibit apple-green birefringence when stained with congo red when seen under a polarizing microscope. Other indicators exist, such as serum amyloid P component binding. Since these are indirect indicators, biophysicists have redefined amyloid using a canonical set of biophysical characteristics (see below), and this seems to cause a low level of conflict between histologists and biophysicists.
