Article Synopsis
- Salicylic acid (SA) hydroxylation is crucial for maintaining SA levels, aiding plant development and defense against pathogens, and is catalyzed by specific enzymes known as SA hydroxylases.
- Researchers have identified a new SA hydroxylase in maize that converts SA into 2,5-dihydroxybenzoic acid (2,5-DHBA) and has distinct kinetic properties from those in other plant species like Arabidopsis and rice.
- A mutation in the S5H gene in maize demonstrates altered growth and increased resistance to a specific pathogen, highlighting the role of SA and related compounds in plant health and defense mechanisms.
Flavonoids are plant specialized metabolites that consist of one oxygenated and two aromatic rings. Different flavonoids are grouped according to the oxidation degree of the carbon rings; they can later be modified by glycosylations, hydroxylations, acylations, methylations, or prenylations. These modifications generate a wide collection of different molecules which have various functions in plants.
