Flavonoid Functions in Plants and Their Interactions with Other Organisms

Plants, 2018
Flavonoids are structurally diverse secondary metabolites in plants, with a multitude of functions. These span from functions in regulating plant development, pigmentation, and UV protection, to an array of roles in defence and signalling between plants ...

The Mitogen‐Activated Protein Kinase GhNTF3 Modulates the Arbuscular Mycorrhizal Symbiosis‐Immunity Trade‐Off in Cotton by Regulating Salicylic Acid Biosynthesis

Advanced Science, EarlyView.
AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...

Functional characterization of key structural genes in rice flavonoid biosynthesis

, 2008
Rice is a model system for monocot but the molecular features of rice flavonoid biosynthesis have not been extensively characterized. Rice structural gene homologs encoding chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H),

An Effector TaCRVP From Tuta Absoluta Oral Secretion Impairs H2O2‐Mediated Plant Defense by Targeting Tomato SlCAT2

Advanced Science, EarlyView.
The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.
