Under certain special conditions, water is pushed up the stem by root pressure.
Symptoms often extend up the stem from the crown rather extending down into the taproot as occurs routinely with Fusarium crown and root rot.
Secreted factors, stem cell neighboring cell interactions, extracellular matrix (ECM), and mechanical properties collectively make up the stem cell microenvironment.
"Once they're posted, NIH is basically out of it," says Judith Greenberg, who's in charge of setting up the stem cell registry.
First, another discovery will shake up the stem cell field, as researchers use knowledge gleaned from embryonic stem cells to create new drugs.
4. Working in batches, pick up the stem of a pepper with your hand, dip the pepper into the batter, and gently drop it into the hot oil.
With the exception of the medullary hyphae of the stem (longitudinally-arranged hyphae making up the stem surface), all hyphae contain clamp connections.
In vivo, the external signals that control stem cell fate collectively make up the stem cell 'niche' [33], [34].
After the start of drought stress, promoter activity started at the base of the stem and then moved up the stem and into the leaf.
