Read on. So what's Methuselah's secret? How can it and its kind survive, much less thrive, in conditions that would strike fear into the phloem of virtually all other plants? After decades of ...
Contrary to small nucleic acids, such as microRNAs that are known to spread systemically through the phloem from a single entry point, Bock's observations of cell-to-cell transport pointed to the ...
Our group is studying the development of vascular cambium by using Arabidopsis thaliana root as a model. Vascular cambium produces xylem (wood) and phloem, and together with the cork cambium, which ...
