UCR scientists identify stem-cell genes that help form plant organs
... RIVERSIDE, Calif. Plant stem-cells are master cells located at the tip of the stem and are part of a structure called the shoot apical meristem
(SAM). Here, the stem cellsall clumped togetherdivide throughout the life of the plant to give rise to other cells, resulting in the formation of ...
Researchers find an essential gene for forming ears of corn

Max Planck researchers make a breakthrough in plant stem cell research
... University of TÃ¼bingen, Germany about a decade ago. Here it was shown that a gene called WUSCHEL has a key influence on how many cells in the apical meristem
actually stay stem cells. However, until now, it was unclear how hormones and regulatory genes, such as WUSCHEL work together to maintain this fine ...
