植物向重性的研究一直受到关注,主要的研究集中在双子叶模式生物拟南芥中,而对单子叶植物的研究却很少。植物对重力感受的方式存在多种解释,但目前大量证据表明淀粉体—平衡石理论较为合理,它认为淀粉体作为平衡石在植物向重性反应中发挥了重要的作用。经过100多年的研究,现已从生理学与遗传学的角度证实了含有淀粉体的根冠中柱细胞和茎的内皮层细胞是植物重力感受的部位,淀粉体作为重力感受器被越来越多的实验证据证明。地球上重力无处不在,要研究微重力对植物体极性生长的影响只能借助于能模拟失重环境的回转器。近年来,人们对植物向重性机制的了解主要来自缺失或缺少
The study of plant-to-gravity has drawn much attention. The main research focuses on the dicotyledonous organism Arabidopsis thaliana, but few studies on monocotyledons. There are many explanations for the way plants feel gravitational force. However, there is a great deal of evidence that the amylopectin-balancestone theory is reasonable at present. It thinks that amyloplasts, as the balance stones, play an important role in plant-to-graver reactions. After more than 100 years of research, it has been confirmed physiologically and genetically that the endocortical cells of the stem and stem cells, which contain the amygdala, are the site of plant gravitation, and amyloplasts are increasingly used as gravimetric receptors Experimental evidence. Gravity is everywhere in the world. To study the effect of microgravity on the polar growth of plants can only be achieved by means of a gyrator that can simulate a weightless environment. In recent years, people’s understanding of plant-to-host mechanisms has mainly come from lacking or lacking
