Plasmodesmata [PDF]

open access: yesThe Plant Cell, 2002
A new paradigm is emerging in plant biology in which proteins and ribonucleoprotein (RNP) complexes play non-cell-autonomous roles in contributing to the control over developmental and physiological processes. Plasmodesmata (PD), the intercellular organelle(s) of the plant kingdom, create the pathway for the cell-to-cell trafficking of these ...

RNAi efficiency, systemic properties, and novel delivery methods for pest insect control : what we know so far [PDF]

open access: yes, 2016
In recent years, the research on the potential of using RNA interference (RNAi) to suppress crop pests has made an outstanding growth. However, given the variability of RNAi efficiency that is observed in many insects, the development of novel approaches

Plasmodesmata and the symplast [PDF]

open access: yesCurrent Biology, 2018
Multicellular organisms rely on cell-to-cell communication and resource exchange to coordinate the various diverse processes involved in growth, development, and environmental responses across tissues and organs. Most complex multicellular organisms have highly organised and specialised anatomies, which develop by processes underpinned by regulated ...

Towards reconciliation of structure with function in plasmodesmata—who is the gatekeeper? [PDF]

open access: yes, 2000
Whilst the structure of higher plant plasmodesmata was first described by Robards (1963. Desmotubule—a plasmodesmatal substructure. Nature 218, 784), and despite many subsequent intensive investigations, there is still much that remains unclear relating ...

Distributing Plant Developmental Regulatory Proteins via Plasmodesmata

open access: yesPlants
During plant development, mobile proteins, including transcription factors, abundantly serve as messengers between cells to activate transcriptional signaling cascades in distal tissues.

Uncharted routes: exploring the relevance of auxin movement via plasmodesmata

open access: yesBiology Open, 2020
Auxin is an endogenous small molecule with an incredibly large impact on growth and development in plants. Movement of auxin between cells, due to its negative charge at most physiological pHs, strongly relies on families of active transporters.

Traffic into silence: endomembranes and post-transcriptional RNA silencing. [PDF]

open access: yes, 2014
microRNAs (miRNAs) and small interfering RNAs (siRNAs) are small RNAs that repress gene expression at the post-transcriptional level in plants and animals. Small RNAs guide Argonaute-containing RNA-induced silencing complexes to target RNAs in a sequence-

Plasmodesmata spread their influence [PDF]

open access: yesF1000Prime Reports, 2015
Plasmodesmata (PDs) are microscopic channels that connect virtually every plant cell to its neighbors. They also provide a route for molecules to access the phloem for systemic movement throughout the plant. In this report, I review recent findings that broaden the potential impact of these channels, by revealing their contribution to auxin movement ...

A Trypsin‐Like Serine Protease ZmNAL1a Fine‐Tunes Maize Floral Transition and Flowering Time

open access: yesAdvanced Science, EarlyView.
This study identifies a trypsin‐like serine protease, ZmNAL1a, that moves from leaves to the shoot apical meristem. ZmNAL1a promotes the floral transition by degrading TOPLESS‐like corepressor REL2, which thereby enhances the expression of key flowering genes through elevating histone acetylation and relieving REL2–ZmEREBP147‐mediated transcriptional ...

Lipids or Proteins: Who Is Leading the Dance at Membrane Contact Sites?

open access: yesFrontiers in Plant Science, 2019
Understanding the mode of action of membrane contact sites (MCSs) across eukaryotic organisms at the near-atomic level to infer function at the cellular and tissue levels is a challenge scientists are currently facing. These peculiar systems dedicated to
