#callose

Average daily temperature controls floral bud formation rate, callose deposition and flower development of Hydrangea macrophylla ‘Early Blue’ Hydrangea macrophylla ‘Early Blue’ was exposed to six different day (DT) and night (NT) and average daily temperatures (ADT) during flower bud formation (DT/NT°C: 12/12, 17/12, 17/17, 22/12, 22/17, 22/22).

PD permeability is dynamically regulated. Under stress, e.g. pathogen infection or temperature shifts, plants deposit #callose at the cell wall, narrowing PD apertures, reducing permeability. We induced callose deposition (*) and found it can fully sever ER, PM and cytosolic continuity.
