Implication

Biochemical study reveals BCM scaffold proteins coordinate chlorophyll synthesis and degradation in Arabidopsis, highlighting a post-translational mechanism for chlorophyll homeostasis.

Key Points

To elucidate how plants post-translationally coordinate the antagonistic pathways of chlorophyll synthesis and breakdown to preserve homeostasis throughout leaf development.
Examined the functional roles and protein interactions of Arabidopsis BALANCE of CHLOROPHYLL METABOLISM paralogs, BCM1 and BCM2, across young and senescing leaf stages.
During early leaf development, BCM1 interacted with GENOMES UNCOUPLED 4 to stimulate Mg-chelatase activity while promoting Mg-dechelatase degradation, stimulating synthesis and preventing breakdown.
At the onset of leaf senescence, BCM2 was upregulated relative to BCM1 and served a conserved role in attenuating chlorophyll degradation.
