The Pseudoenzyme PDX1.2 Sustains Vitamin B₆ Biosynthesis as a Function of Heat Stress

Plants sense temperature changes and respond by altering growth and metabolic activity to acclimate to the altered environmental conditions. The B vitamins give rise to vital coenzymes that are indispensable for growth and development but their inherent reactive nature renders them prone to destruction especially under stress conditions. Therefore, plant survival strategies would be expected to include mechanisms to sustain B vitamin supply...
