Analysis of a novel mutant allele of GSL8 reveals its key roles in cytokinesis and symplastic trafficking in Arabidopsis [PDF]
BMC Plant Biology, 2018 Background Plant cell walls are mainly composed of polysaccharides such as cellulose and callose. Callose exists at a very low level in the cell wall; however, it plays critical roles at different stages of plant development as well as in defence against

Multicellularity and the Need for Communication—A Systematic Overview on (Algal) Plasmodesmata and Other Types of Symplasmic Cell Connections [PDF]
Plants, 2023 In the evolution of eukaryotes, the transition from unicellular to simple multicellular organisms has happened multiple times. For the development of complex multicellularity, characterized by sophisticated body plans and division of labor between ...

Plasmodesmata play a key role in leaf vein patterning
PLoS Biology, 2022 Leaf veins provide a vital transport route in plants. The formation of leaf vein patterns has fascinated many scientists. In PLOS Biology, Linh and Scarpella reveal that transport through plasmodesmata plays a key role in vein patterning.

Plasmodesmata-Involved Battle Against Pathogens and Potential Strategies for Strengthening Hosts [PDF]
Frontiers in Plant Science, 2021 Plasmodesmata (PD) are membrane-lined pores that connect adjacent cells to mediate symplastic communication in plants. These intercellular channels enable cell-to-cell trafficking of various molecules essential for plant development and stress responses,

Citrus psorosis virus movement protein contains an aspartic protease required for autocleavage and the formation of tubule-like structures at plasmodesmata [PDF]
, 2018 Plant virus cell-to-cell movement is an essential step in viral infections. This process is facilitated by specific virus-encoded movement proteins (MPs), which manipulate the cell wall channels between neighboring cells known as plasmodesmata (PD ...

Variable temperature processing by plasmodesmata regulates robust bud dormancy release [PDF]
Nature CommunicationsDormancy is a key mechanism in perennial plants in boreal and temperate regions, protecting buds from winter damage by repressing precocious bud break before spring onset.

The Extended Synaptotagmins of Physcomitrium patens [PDF]
PlantsMembrane contact sites (MCSs) between the endoplasmic reticulum and the plasma membrane enable the transport of lipids without membrane fusion. Extended Synaptotagmins (ESYTs) act at MCSs, functioning as tethers between two membrane compartments.
