Example Sentences

"Regarding the ferric reductase activity of HYP1, our results demonstrate that this function is critical to prevent malate-induced Fe overaccumulation in the apoplast and to maintain cell elongation and meristem integrity in root tips exposed to low P," explains Dr. Ricardo Giehl.

From Science Daily

Some eH2O2 moves from the apoplast into the cytoplasm through channel proteins called aquaporins3.

From Nature

However, unlike the cytoplasm, the apoplast contains relatively few molecules that counteract oxidation1 — and so ROS, including H2O2, can survive for much longer in the apoplast than in the cytoplasm.

From Nature

The protein has an intracellular kinase enzyme domain, and an extracellular domain that protrudes into the apoplast — the compartment between a plant cell’s plasma membrane and the cell wall.

From Nature

It is produced in an extracellular space between the plasma membrane and cell wall called the apoplast, in response to a range of factors, including stressors, plant hormones such as abscisic acid, and physical or chemical changes outside the cell1.
