ManipulatingExpressionofTonoplastTransporters
Plant vacuoles have multifaceted roles including turgor maintenance, cytosolic pH and ionic homeostasis, plant protection against environmental stress, detoxification, pigmentation, and cellular signaling. These roles are achieved through the coordinated activities of many proteins in the tonoplast (vacuolar membrane), of which the proton pumps and ion transporters have been modified for improved abiotic ......阅读全文

在双链 DNA 分子中，只有一条链转录成 mRNA，这条链称为有意义链(sense strand)，该基因的另一条链则称反意义链(antisense strand)。在含有许多基因的 DNA 双链中，每个基因的有意义链并不是在同一条 DNA 链上。也就是说，一条链上既具有某些基因的有意义链，
