Phloem transport and drought
WebbFör 1 dag sedan · It is known that the transport direction of phloem is from source to sink. This is inconsistent with our findings that PbHMGR1 can be transported upward from the root ( Fig. 4 ). The macromolecules such as RNA and protein are transported via the pressure flow system of the phloem to specific developing tissues, thereby maintaining … Webb1 juni 2024 · In the following, we will discuss whether the relatively high resistance of gymnosperm SEs can be reconciled with the observed transport rates according to the Münch mechanism of phloem transport or if alternative mechanisms, such as a relay [10, 11], would provide a better explanation.Furthermore, the related topics of phloem loading …

Webb1 feb. 2024 · We concluded that prolonged drought affected phloem transport capacity through a change in anatomy and that the slowdown of phloem transport under drought likely resulted from a reduced driving force due to lower hydrostatic pressure between the source and sink organs. Webb22 maj 2024 · Drought has also been suggested to cause phloem transport failure (Sevanto, 2014). Thus, the possible impairment of C transport in the phloem under drought and pathogen infection warrants further research. 4.2 Differences between species.
