Phloem transport and drought [PDF]
Journal of Experimental Botany, 2014 Drought challenges plant water uptake and the vascular system. In the xylem it causes embolism that impairs water transport from the soil to the leaves and, if uncontrolled, may even lead to plant mortality via hydraulic failure. What happens in the phloem, however, is less clear because measuring phloem transport is still a significant challenge to ...

Planta, 1970
Translocation of (14)C-labelled photosynthate across 2 cm long carrot calluses was not detectable even 6 hours after a 30 min (14)CO2 pulse. This is consistent with the discontinuous nature of the phloem as a whole, although small strands of contiguous, well differentiated sieve cells with companion cells were readily seen in electron micrographs.

Abstract Flow of photo assimilates into various compartments or biochemical pathways within source and sink regions. In source organs, carbon is allocated to various uses including export. In a sink organ, carbon enters into compartments or is used for synthesis, storage, or energy metabolism.

Current Opinion in Plant Biology, 2018
The survival of all vascular plants depends on phloem and xylem, which comprise a hydraulically coupled tissue system that transports photosynthates, water, and a variety of other molecules and ions. Although xylem hydraulics has been extensively studied, until recently, comparatively little is known quantitatively about the phloem hydraulic network ...

Abstract This chapter delves into the intertwined narratives of individuals whose works, though not explicitly focused on environmentalism, subtly contribute to a rich tradition of plant thinking in the Indian subcontinent. Through a mosaic of interconnected lives and creative endeavours, the chapter illuminates a hidden thread of ...

Localized application of chemicals which inhibit metabolism, anoxia and low temperature have been used as tools in basic research to assess the role of energy metabolism in the various stages of the translocation process. The results of these studies are reviewed in this chapter.
