... apoplast. The new cells become rounded and have a thin, primary cell wall. The cells exercise their ability (now) to divide and divide and divide. Because they are thin-walled, dividing cells, and because they contain the genetic codes for forming all parts of the tree, some of the cells begin to differentiate to form sprouts, prop ...

... pathways, but organisms with less compact genomes appear to repair most breaks generated in mitotic cells via NHEJ. We are interested in determining the genetic basis of NHEJ in plants, using ... . In wild-type cells, the cell cycle is slowed so that replication can be accurately completed before progression into mitosis. atr null plants lack this safeguard, and dividing cells die when exposed to ...
