Phloem unloading in Arabidopsis roots is convective and regulated by the phloem-pole pericycle

eLife, 2017
In plants, a complex mixture of solutes and macromolecules is transported by the phloem. Here, we examined how solutes and macromolecules are separated when they exit the phloem during the unloading process.

Plasmodesmata and their role in assimilate translocation

Journal of Plant Physiology, 2022
During multicellularization, plants evolved unique cell-cell connections, the plasmodesmata (PD). PD of angiosperms are complex cellular domains, embedded in the cell wall and consisting of multiple membranes and a large number of proteins. From the beginning, it had been assumed that PD provide passage for a wide range of molecules, from ions to ...

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

Applications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Enviromics crosstalk between internal and external plant environments for enhanced adaptation and de novo domestication

iMeta, EarlyView.
Climate change demands accelerated plant adaptation and de novo domestication. Yet current enviromics focuses disproportionately on external environments, neglecting internal dynamics—gene expression, metabolic flux, and signal transduction—within predictive envirotyping frameworks.

Salt glands in exo‐recretohalophytes: Development, physiological functions, and prospects for improving crop salt tolerance

Journal of Integrative Plant Biology, EarlyView.
This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

Characterization of cluster-III HIPP proteins targeted to plasmodesmata in Arabidopsis thaliana [PDF]

, 2020
The plant hormone cytokinin plays essential regulatory roles in many aspects of plant growth and development. Cellular cytokinin concentrations are controlled by numerous interconnected metabolic reactions, such as hormone biosynthesis, metabolic ...

Interaction between Movement Proteins of Hibiscus green spot virus

Viruses, 2022
Movement proteins (MPs) of plant viruses enable the translocation of viral genomes from infected to healthy cells through plasmodesmata (PD). The MPs functions involve the increase of the PD permeability and routing of viral genome both to the PD ...

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

New Phytologist, EarlyView.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.
