Phloem transport in trees.
Phloem is like an enigmatic central banker: we know how important phloem is to plant function, but very little about how phloem functions as part of a whole-plant economy. Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage. At photosynthetic tissues, carbohydrates are loaded into phloem (Rennie and...
متن کاملPhloem transport: Are you chaperoned?
Long-distance transport via the vasculature in plants is critical for nutrient dissemination, as well as transport of growth regulatory molecules such as hormones. Evidence is now accumulating that protein and RNA molecules also use this transport pathway, possibly to regulate developmental and physiological processes.

posts are held by men. It isn’t always easy for young women to have social confidence necessary to not only engage but stand out in their respective scientific communities and the competition for faculty positions is stiff. That being said, I think a lot has changed for the better in the last 20 years that I have been in science and the climate is still improving. A second challenge that women ...
متن کاملUniversality of phloem transport in seed plantspce_2472
Since Münch in the 1920s proposed that sugar transport in the phloem vascular system is driven by osmotic pressure gradients, his hypothesis has been strongly supported by evidence from herbaceous angiosperms. Experimental constraints made it difficult to test this proposal in large trees, where the distance between source and sink might prove incompatible with the hypothesis. Recently, the the...
متن کاملPost-phloem transport: principles and problems.
The movement of assimilates from the sieve element/companion cell complex to sites of utilization has been examined in an extensive array of sinks possessing diverse anatomies. This work has been reviewed with respect to the pathways taken, the conductances and driving forces for movement along the pathways, and interaction between the apoplast and symplast. Most investigations to date have bee...
