Cytokinin downregulates Photosystem II photochemistry during prolonged darkness in a phytochrome B‐dependent manner

New Phytologist, Volume 250, Issue 6, Page 3846-3866, June 2026.
Cytokinin–phyB signaling modulates PSII photochemistry during prolonged darkness. Summary Cytokinins (CKs) delay dark‐induced senescence, but how they tune photosynthetic function in darkness remains unclear. We investigated the effects of classical aromatic CK benzylaminopurine and CK‐derived compound 1‐(2‐methoxyethyl)‐3‐(1,2,3‐thiadiazol‐5‐yl)urea ...

Mutations in theCCD4Carotenoid Cleavage Dioxygenase Gene of Yellow-Flesh Peaches

Bioscience, Biotechnology, and Biochemistry, 2013
Peach trees bear either white- or yellow-flesh fruit. We found that Japanese peach cultivars have two types of mutation in a carotenoid catabolic gene, CCD4: the insertion of a retrotransposon, and a frame shift in the microsatellite sequences of the first exon. CCD4 in yellow-flesh peaches was disrupted by these mutations.

Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...

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

Introducing CCD1 into isolated Rhodotorula strain enhances flavor production and improves cigar fermentation

Frontiers in Bioengineering and Biotechnology
IntroductionThe fermentation process plays an important role in enhancing the quality of cigar tobacco leaves. Through fermentation, microbial metabolism can degrade aromatic precursors and macromolecules, which increases the content of aroma compounds ...

Comparison of carotenoid, chlorophyll concentrations and their biosynthetic transcript levels in different coloured cauliflower

Horticultural Plant Journal
Carotenoids and chlorophylls are among the most widely distributed pigments in nature that play essential roles in the photosynthetic apparatus and confer diverse colours in plants. Among all vegetables, cauliflower (Brassica oleracea L. ssp.
