however, stem cells have even wider significance as central players in thedevelopmentof complex organisms, which include plants. There are surprising similarities between stem cells found in plants and in animals.

When DNA damage occurs, the cells have the capacity to detect it and cause programmed cells to die, preventing the propagation of the damaged genetic code to the rest of the plant tissues. This process has similarities to the safeguard mechanism found in animal cells, which has been broadly ...

根据语境“Plants turning towards the sun is commonly found in nature. They direct their stems* so their flowers always face the sunlight during the day.”可知,植物向着太阳,让自己的花茎朝向阳光,这叫做“向光性”。故选A。【小题2】细节理解题。根据短文第六段“A ‘stem’ made from a special ...
Stem cells: 来自 dx.doi.org 喜欢 0 阅读量: 13 作者: PN Benfey 摘要: Homologous genes have recently been shown to regulate stem cell maintenance in animals and plants. This discovery should facilitate elucidation of the poorly understood factors that control stem cell maintenance and ...
stem cells in plants, as well as their evolution (Kofuji and Hasebe2014). Molecular genetic studies over the last two decades using the model bryophyte speciesPhyscomitrium(Physcomitrella)patens(P. patens) andMarchantia polymorpha(M. polymorpha) have greatly helped our understanding of the evolution...
12.1 Stem cells and hormonal regulation of stem cell activity One of the key features in high plants is their continuous postembryonic organogenesis with remarkable developmental plasticity to cope with ever-changing environmental stimuli. This plasticity relies on the formation, maintenance, and different...
Superoxide anion is thought to be a natural by-product with strong oxidizing ability in all living organisms and was recently found to accumulate in plant meristems to maintain stem cells in the shoot and undifferentiated meristematic cells in the root. Here we show that the DNA demethylase repre...
Using a computational approach we show that a mixture of monomers and heterodimers of the transcription factors WUSCHEL and HAIRY MERISTEM is sufficient to pattern the stem cell niche, and predict that immobile heterodimers form a regulatory “pocket” surrounding the stem cells. The model achieves ...
