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.

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 ...

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 ...

Sieve Plate Pores in the Phloem and the Unknowns of Their Formation
Plants, 2019 Sieve pores of the sieve plates connect neighboring sieve elements to form the conducting sieve tubes of the phloem. Sieve pores are critical for phloem function.

Quantification of plasmodesmatal endoplasmic reticulum coupling between sieve elements and companion cells using fluorescence redistribution after photobleaching [PDF]
, 2006 Transgenic tobacco (Nicotiana tabacum) was studied to localize the activity of phloem loading during development and to establish whether the endoplasmic reticulum (ER) of the companion cell (CC) and the sieve element (SE) reticulum is continuous by ...

Phytoplasma-Triggered Ca2+ Influx Is Involved in Sieve-Tube Blockage
Molecular Plant-Microbe Interactions, 2013 Phytoplasmas are obligate, phloem-restricted phytopathogens that are disseminated by phloem-sap-sucking insects. Phytoplasma infection severely impairs assimilate translocation in host plants and might be responsible for massive changes in phloem ...

Screening Mechanism and Properties of a Cantilevered Vibrating Sieve for Particles Processing
Applied Sciences, 2019 Screening of fine wet particles or near-aperture particles by traditional screen devices is often not quite effective for sieve plugging. Different from traditional rigid regular mesh sieves, a cantilevered vibrating sieve (CVS) with open screen holes ...

Live imaging of companion cells and sieve elements in Arabidopsis leaves.
PLoS ONE, 2015 The phloem is a complex tissue composed of highly specialized cells with unique subcellular structures and a compact organization that is challenging to study in vivo at cellular resolution.
