Molecular Plant Pathology, Volume 27, Issue 4, April 2026.This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Microfluidic Screening of Electrophoretic Mobility Shifts Elucidates Riboswitch Binding Function [PDF]
, 2016 Riboswitches are RNA sensors that change conformation upon binding small molecule metabolites, in turn modulating gene expression. Our understanding of riboswitch regulatory function would be accelerated by a high-throughput, quantitative screening tool ...

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco
Plant Biotechnology Journal, Volume 24, Issue 4, Page 2541-2558, April 2026.ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Novel TPP-riboswitch activators bypass metabolic enzyme dependency
Frontiers in Chemistry, 2014 Riboswitches are conserved regions within mRNA molecules that bind specific metabolites and regulate gene expression. TPP-riboswitches, which respond to thiamine pyrophosphate (TPP), are involved in the regulation of thiamine metabolism in numerous ...

The Structure of the Guanidine-II Riboswitch
Cell Chemical Biology, 2017 The guanidine-II (mini-ykkC) riboswitch is the smallest of the guanidine-responsive riboswitches, comprising two stem loops of similar sequence. We have solved high-resolution crystal structures of both stem loops for the riboswitch from Gloeobacter violaceus. The stem loops have a strong propensity to dimerize by intimate loop-loop interaction.

Structural basis for ligand binding to the guanidine-II riboswitch [PDF]
, 2017 The guanidine-II riboswitch, also known as mini-ykkC, is a conserved mRNA element with more than 800 examples in bacteria. It consists of two stem–loops capped by identical, conserved tetraloops that are separated by a linker region of variable length ...
