Interactions among tobacco sieve element occlusion (SEO) proteins. [PDF]
Plant Signal Behav, 2012 Angiosperms transport their photoassimilates through sieve tubes, which comprise longitudinally-connected sieve elements. In dicots and also some monocots, the sieve elements contain parietal structural proteins known as phloem proteins or P-proteins. Following injury, P proteins disperse and accumulate as viscous plugs at the sieve plates to prevent ...

SEORious business: structural proteins in sieve tubes and their involvement in sieve element occlusion [PDF]
Journal of Experimental Botany, 2014 The phloem provides a network of sieve tubes for long-distance translocation of photosynthates. For over a century, structural proteins in sieve tubes have presented a conundrum since they presumably increase the hydraulic resistance of the tubes while no potential function other than sieve tube or wound sealing in the case of injury has been suggested.

Viral Systemic Movement Is Enhanced by Alteration of a Structural Phloem Protein by the Insect Vector [PDF]
Advanced ScienceThe ability to access and exploit the vascular system is essential for viral systemic spread within plant hosts. Insect‐borne viruses can be released from the vector's stylets into plant phloem together with saliva components that facilitate viral ...

Local auxin competition explains fragmented differentiation patterns
Nature Communications, 2020 Sieve element differentiation in Arabidopsis roots requires two antagonistic regulators of auxin efflux, BRX and PAX. Here the authors show that together they coordinate sieve element formation by preventing cell fate bistability emerging from AUX1 ...
