Ultimately, chlorophyll production is inhibited, and plant foliage turns white and appears bleached. Although injury symptoms are similar with these herbicides; the specific site of action is different. The Carotenoid Biosynthesis Inhibitors are classified in three subgroups based on modes of action. These groups are:

The pathway of chlorophyll catabolism. Chlorophyll is the central molecule that connects the biosynthetic and the catabolic pathway as well as the ‘chlorophyll cycle’. : ALA, 5‐aminolaevulinic acid; CAO, chlorophyll(ide) a oxygenase; CBR, chlorophyll(ide) b reductase; Chl, chlorophyll; Chlase, chlorophyllase; Chlide, chlorophyllide; CS, chlorophyll synthase; HCAR, 7‐hydroxymethyl chlorophyll(ide) a reductase; PAO, pheophorbide a oxygenase; pFCC, primary fluorescent chlorophyll catabolite; Pheide , pheophorbide ; Pchlide, protochlorophyllide; RCC, red chlorophyll catabolite; RCCR, RCC reductase.

These studies provided the first detailed understanding of genes involved in bacteriochlorophyll a biosynthesis.

This review is centered on a discussion of our current understanding of bacterial, algal, and plant genes that code for enzymes in the Mg-branch of the tetrapyrrole biosynthetic pathway that are responsible for synthesis of chlorophylls and bacteriochlorophylls.

In the short time since these studies were initiated, most of the chlorophyll biosynthesis genes have been identified by virtue of their ability to complement bacteriochlorophyll a biosynthesis mutants as well as by sequence homology comparisons.

The isoxazolidinone herbicide clomazone and the triazole herbicide amitrol are examples of this group. The modes of action of these herbicides are not clearly illustrated. Recent evidence, however, suggests that clomazone is metabolized to another form of clomazone, which is herbicidal active and inhibits 1-deoxy-D-xyulose 5-phosphate synthase (DOXP), a key component to plastid isoprenoid synthesis. Amitrole inhibits accumulation of chlorophyll and carotenoids in the light, although the specific site of action has not been determined.

These herbicides applied as preemergence or postemergence in different cropping systems, landscape and ornamental, industrial use, and aquatic setting. In general, they are active on broadleaf weeds but control selected grasses. The Carotenoid Biosynthesis Inhibiting herbicides interfere directly or indirectly with carotenoid production that protects chlorophyll from excessive light and photo oxidation.

Flow chart of the metabolic pathway of tetrapyrrole biosynthesis towards the end products, chlorophyll and protohaem. Potential feedback control mechanisms in the metabolic pathway of tetrapyrroles are indicated. The synthesis of 5‐aminolaevulinate from glutamate is the rate‐limiting step of tetrapyrrole biosynthesis. Feedback regulation on the enzymes of the 5‐aminolevulinic acid pathway can start out from various sites: at the level of haem formation, at the level of protochlorophyllide reduction and at the beginning of the Mg‐porphyrin branch.
