Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

The Common Bean miR172c microRNA, a Relevant Regulator of the N-Fixing Symbiosis, Is Activated by SPL and AGL/MADS-Domain Transcription Factors. [PDF]

Physiol Plant
ABSTRACT Nitrogen‐fixing symbiosis (NFS) between rhizobia and legume plants is a complex and tightly regulated process. Modules of microRNAs (miRNAs) and their targets from different legumes, such as miR156‐SPL and miR172‐AP2‐1, form part of complex cascades relevant for the regulation of NFS.

A Method to Visualize Cell Proliferation of <i>Arabidopsis thaliana</i>: A Case Study of the Root Apical Meristem. [PDF]

Plant Direct
ABSTRACT Plant growth and development rely on a delicate balance between cell proliferation and cell differentiation. The root apical meristem (RAM) of Arabidopsis thaliana is an excellent model to study the cell cycle due to the coordinated relationship between nucleus shape and cell size at each stage, allowing for precise estimation of the cell ...

Pseudomonas syringae Lipopolysaccharide Synthesis Gene wbpL Displays Heterogeneous Expression Within In Vitro and In Planta Populations. [PDF]

Microbiologyopen
Genetically identical bacteria in the same environment sometimes behave differently. This happens for the expression of wbpL, a gene of plant pathogenic Pseudomonas syringae that shapes the bacterial surface and is important for infection and immunity.
