Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics

Advanced Science, EarlyView.
Small nanoplastics can disrupt cell integrity and inhibit cell division in meristem zone of plant root. The plants can counteract the cell damage by upregulating genes associated with root meristem maintenance and increasing auxin accumulation by PIN2 transport inhibition.

Agrobacterium Mediated Transformation of Fld and GUS Genes into Canola for Salinity Stress [PDF]

Journal of Stress Physiology & Biochemistry, 2013
Salinity is one of the major abiotic stress which limits wide spread canola cultivation. One way to overcome this problem could be transfection, to produce tolerable species. Cotyledonary and hypocotyls explants obtained from 4 and 7 days old seedling of

A Versatile Assay for the Identification of RNA Silencing Suppressors Based on Complementation of Viral Movement

Molecular Plant-Microbe Interactions, 2008
The cell-to-cell movement of Turnip crinkle virus (TCV) in Nicotiana benthamiana requires the presence of its coat protein (CP), a known suppressor of RNA silencing. RNA transcripts of a TCV construct containing a reporter gene (green fluorescent protein)

An Engineered Probiotic Consortium Based on Quorum‐Sensing for Colorectal Cancer Immunotherapy

Advanced Science, EarlyView.
This work develops an engineered probiotic consortium sensing pH, hypoxia, and lactate in the tumor microenvironment. It releases a lactate‐depleting enzyme (LdhA) and a PD‐L1 nanobody. In humanized mouse models (MC38 and HT‐29 tumors), it achieves durable oscillations, suppresses tumors, activates CD8+, CD4+, IFN‐γ+ T cells, and reduces Foxp3 ...

T-DNA transfer from Agrobacterium tumefaciens to the ectomycorrhizal fungus Pisolithus microcarpus Transferencia de T-DNA de Agrobacterium tumefaciens al hongo ectomicorrícico Pisolithus microcarpus

Revista Argentina de Microbiología, 2005
The model ectomycorrhizal fungus Pisolithus microcarpus isolate 441 was transformed by using Agrobacterium tumefaciens LBA1100 and AGL-1. The selection marker was the Shble gene of Streptoallotecius hidustanus, conferring resistance to phleomycin, under ...

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Tomato prosystemin gene in other Solanaceae [PDF]

, 2009
Systemin, an octadeca-peptide isolated from tomato, is a signalling molecule involved in local and systemic wound response. It regulates the activation of more than twenty defensive genes in tomato plants in response to herbivore attacks.

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

Advanced Science, EarlyView.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

Silencing Agrobacterium oncogenes in transgenic grapevine results in strain-specific crown gall resistance [PDF]

, 2013
Crown gall disease of grapevine induced by Agrobacterium vitis or Agrobacterium tumefaciens causes serious economic losses in viticulture. To establish crown gall-resistant lines, somatic proembryos of Vitis berlandieri × V. rupestris cv. 'Richter 110'

Actin Isovariant ACT2‐Mediated Cellular Auxin Homeostasis Regulates Lateral Root Organogenesis in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.
