Vitamins for enhancing plant resistance.

Area of Science:

• Plant Science
• Biochemistry
• Molecular Biology

Background:

• Induced resistance (IR) is a sustainable plant defense strategy against diseases.
• Vitamins are increasingly recognized for their role in activating plant innate immunity.
• Their safety and cost-effectiveness make them attractive for crop protection.

Purpose of the Study:

• To review vitamins that induce plant disease resistance.
• To elucidate the molecular and cellular mechanisms of vitamin-induced resistance.
• To explore the hormonal signaling networks regulating vitamin activity in plants.

Main Methods:

• Literature review of studies on vitamins and plant induced resistance.
• Analysis of molecular and cellular mechanisms of vitamin action.
• Examination of hormonal signaling pathways involved in vitamin-mediated defense.

Main Results:

• Several vitamins, including thiamine (B1), riboflavin (B2), menadione sodium bisulfite (K3), PABA (Bx), and folic acid (B9), effectively induce disease resistance.
• Ascorbic acid (C) and tocopherols (E) are also implicated in IR mechanisms.
• Vitamins modulate specific host-defense pathways and interact with conventional elicitors.

Conclusions:

• Vitamins are potent inducers of plant disease resistance, acting through diverse molecular and cellular mechanisms.
• Hormonal signaling networks are crucial for vitamin-signal transduction during induced resistance.
• Understanding these pathways offers a biochemical model for enhancing plant defense strategies.
