Phytoplasma infection in tomato is associated with re-organization of plasma membrane, ER stacks and actin filaments in sieve elements [PDF]
Frontiers in Plant Science, 2015 Phytoplasmas, biotrophic wall-less prokaryotes, only reside in sieve elements of their host plants. The essentials of the intimate interaction between phytoplasmas and their hosts are poorly understood, which calls for research on potential ...

Thaumatin-like proteins are differentially expressed and localized in phloem tissues of hybrid poplar [PDF]
BMC Plant Biology, 2010 Background Two thaumatin-like proteins (TLPs) were previously identified in phloem exudate of hybrid poplar (Populus trichocarpa × P. deltoides) using proteomics methods, and their sieve element localization confirmed by immunofluorescence.

Filamentous sieve element proteins are able to limit phloem mass flow, but not phytoplasma spread. [PDF]
J Exp Bot, 2017 In Fabaceae, dispersion of forisomes\u2014highly ordered aggregates of sieve element proteins\u2014in response to phytoplasma infection was proposed to limit phloem mass flow and, hence, prevent pathogen spread.

Numerical Modeling of Thermal Behavior during Lunar Soil Drilling
Aerospace, 2023 This paper presents a detailed thermal simulation analysis of the drilling process for icy soil in the lunar polar region. The aim is to investigate the temperature changes that occur in the debris removal area during the drilling process. We developed a

Non-dispersive phloem-protein bodies (NPBs) of Populus trichocarpa consist of a SEOR protein and do not respond to cell wounding and Ca2+ [PDF]
PeerJ, 2018 Differentiating sieve elements in the phloem of angiosperms produce abundant phloem-specific proteins before their protein synthesis machinery is degraded.

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 ...

Design and Motion Process of Air-Sieve Castor Cleaning Device Based on Discrete Element Method
Agriculture, 2023 In order to improve the cleaning effect of the castor shelling mixture, an air-sieve castor cleaning device was developed. The structure of the cleaning device was optimized by experiment and simulation based on the discrete element method.

Functional Sieve Element Protoplasts
Plant Physiology, 2007 Sieve element (SE) protoplasts were liberated by exposing excised phloem strands of Vicia faba to cell wall-degrading enzyme mixtures. Two types of SE protoplasts were found: simple protoplasts with forisome inclusions and composite twin protoplasts-two protoplasts intermitted by a sieve plate-of which one protoplast often includes a forisome ...
