Activity of nAChRs containing α9 subunits modulates synapse stabilization via bidirectional signaling programs [PDF]

open access: yes, 2009
Although the synaptogenic program for cholinergic synapses of the neuromuscular junction is well known, little is known of the identity or dynamic expression patterns of proteins involved in non-neuromuscular nicotinic synapse development.

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

New Method for the Selection of Multicopy Transformants of Pichia pastoris, Using 3-Amino-1,2,4 Triazol

open access: yesBioTechniques, 2000
The methylotrophic yeast Pichia pastoris has been successfully used for the expression of many heterologous proteins. The level of expression of some of these proteins depends on the copy number of the gene inserted into the yeast genome. Several methods

miR825‐5p‐regulated TNLs govern Arabidopsis resistance to Tetranychus urticae and Pieris brassicae

open access: yesNew Phytologist, Volume 247, Issue 6, Page 2927-2944, September 2025.
Summary MicroRNAs are essential regulators in plant resistance to biotic stresses, but their specific roles in the plant–herbivore context require deeper investigation. Here, we studied how the Arabidopsis miR825‐5p differentially modulates certain TNLs (MRT1, MRT2, and MIST1), triggering defensive responses against the sucking acari Tetranychus ...

Methylobacterium sp. 2A is a plant growth-promoting rhizobacteria that has the potential to improve potato crop yield under adverse conditions [PDF]

open access: yes, 2020
A Gram-negative pink-pigmented bacillus (named 2A) was isolated from Solanum tuberosum L. cv. Desirée plants that were strikingly more developed, presented increased root hair density, and higher biomass than other potato lines of the same age.

The role of insularity: Plants have few ornithophilous traits but are visited by morphologically more distinct hummingbirds in the Caribbean islands

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1678-1692, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions.
