Spider Mites: Genetic Models to Inform Herbivore and Chelicerate Biology

BioEssays, Volume 48, Issue 5, May 2026.
Chelicerates include spiders, scorpions and ticks, and also spider mites that damage crops. Many of the features that make spider mites crop pests have facilitated their adoption as genetically tractable chelicerates. The expanding genetic toolkit developed using spider mites has potential to inform genetic studies in other chelicerates as well ...

Pro‐Vitamin A Biofortified Cavendish Banana: Trait Stability in the Field

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3327-3344, May 2026.
ABSTRACT Vitamin A deficiency (VAD), a major global health concern, has driven efforts to develop staple crops with enhanced pro‐vitamin A (pVA) content. Delivering meaningful nutritional benefits, however, requires technologies that maintain elevated carotenoid levels under field conditions. Previous proof‐of‐concept work demonstrated that pVA content

Substrate specificity and kinetics for VP14, a carotenoid cleavage dioxygenase in the ABA biosynthetic pathway

Biochimica et Biophysica Acta (BBA) - General Subjects, 2003
The plant growth regulator, abscisic acid (ABA), is synthesized via the oxidative cleavage of an epoxy-carotenoid. Specifically, a double bond is cleaved by molecular oxygen and an aldehyde is formed at the site of cleavage in both products. The Vp14 gene from maize encodes an oxidative cleavage enzyme for ABA biosynthesis and the recombinant VP14 ...

StNCED2 confers drought tolerance via enhanced ABA synthesis

Plant Stress
Carotenoid cleavage dioxygenases (CCDs), crucial non-heme pigment oxygenases regulating plant stress responses, remain poorly characterized functionally in potato despite extensive research on this gene family.

LINKAGE MAPPING OF CAROTENOID CLEAVAGE DIOXYGENASE-4 FAMILY IN LENTIL GENOME

Turkish Journal Of Field Crops, 2018
Plant carotenoid cleavage dioxygenases (CCDs) are a family of enzymes that catalyze the carotenoids oxidative cleavage and apocarotenoids and also play a crucial role in plant development and growth. CDD4 is a member of CDDs. It has two isoforms as CCD4a and CCD4b and they encode enzymes to catalyze the cleavage of carotenoids forming pigment compounds

Biochemical investigations of the carotenoid cleavage dioxygenase enzyme family [PDF]

The biosynthesis of the plant hormones strigolactone and abscisic acid is, in part, controlled by a family of enzymes known as the carotenoid cleavage dioxygenases (CCDs), which perform an oxidative cleavage reaction on a carotenoid substrate (9’-cis-neoxanthin for abscisic acid and 9-cis-β-carotene and 9-cis-β-apo-10’-carotenal for strigolactone) to ...

Carotenoid cleavage dioxygenase catalyzes carotenoid degradation and regulates carotenoid accumulation and petal coloration in Zinnia elegans

Ornamental Plant Research
Carotenoids are one of the important coloring substances in the ray florets of Zinnia elegans. Carotenoid cleavage dioxygenase (CCD) directly affects carotenoid contents by cleaving the double bond of carotenoids, thereby affecting the flower color. However, few reports have elucidated its function in Zinnia elegans.

Role of carotenoid cleavage dioxygenases in volatile emissions and insect resistance in Arabidopsis [PDF]

, 2013
In Arabidopsis thaliana, carotenoid degradation by enzymatic oxidative cleavage is catalyzed by nine CCD and NCED enzymes; this cleavage produces an array of terpenoid products that are collectively known as apocarotenoids, which include volatile and non-volatile compounds. Previous studies on CCD1 revealed that its overexpression in A.
