Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

An unbiased approach elucidates variation in (S)-(+)-linalool, a context-specific mediator of a tri-trophic interaction in wild tobacco

open access: yes, 2019
Plant volatile organic compounds (VOCs) mediate many interactions, and the function of common VOCs is especially likely to depend on ecological context.

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

open access: yesCytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Selenium biofortification: integrating one health and sustainability

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Selenium (Se) biofortification in crops has emerged as a promising strategy to address global Se deficiencies and enhance both agricultural productivity and human health. Increasing the Se content of crops through biofortification improves their resilience to abiotic and biotic stresses and boosts their nutritional value.

Tree Tobacco Extract (Nicotiana glauca) as a Plithogenic Bioinsecticide Alternative for Controlling Fruit Fly (Drosophila immigrans) using n-SuperHyperGraphs [PDF]

open access: yesNeutrosophic Sets and Systems
Concern regarding the negative effects of synthetic pesticides has driven the development of bioinsecticides as sustainable alternatives. Consequently, Nicotiana glauca has gained prominence for its insecticidal properties due to phytochemical compounds ...

Calcium signaling in plant defense

open access: yesNew Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

A Peroxidase Gene Promoter Induced by Phytopathogens and Methyl Jasmonate in Transgenic Plants

open access: yesMolecular Plant-Microbe Interactions, 1997
The expression of two closely related peroxidase isogenes, Shpx6a and Shpx6b, of the legume Stylosanthes humilis was studied using isogene-specific reverse transcriptase PCR techniques.

A petunia ethylene-responsive element binding factor, PhERF2, plays an important role in antiviral RNA silencing. [PDF]

open access: yes, 2016
Virus-induced RNA silencing is involved in plant antiviral defense and requires key enzyme components, including RNA-dependent RNA polymerases (RDRs), Dicer-like RNase III enzymes (DCLs), and Argonaute proteins (AGOs).

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

open access: yesNew Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.
