Does zaxinone counteract strigolactones in shaping rice architecture? [PDF]
Plant Signaling and Behavior, 2023 The cleavage of plant carotenoids leads to apocarotenoids, a group of metabolites including precursors of the hormones strigolactones (SLs) and abscisic acid, regulatory and signaling molecules.

New Series of Zaxinone Mimics (MiZax) for Fundamental and Applied Research [PDF]
Biomolecules, 2023 The apocarotenoid zaxinone is a recently discovered regulatory metabolite required for proper rice growth and development. In addition, zaxinone and its two mimics (MiZax3 and MiZax5) were shown to have a remarkable growth-promoting activity on crops and

Zaxinone synthase controls arbuscular mycorrhizal colonization level in rice [PDF]
Plant Journal, 2022 SUMMARY The Oryza sativa (rice) carotenoid cleavage dioxygenase OsZAS was described to produce zaxinone, a plant growth‐promoting apocarotenoid. A zas mutant line showed reduced arbuscular mycorrhizal (AM) colonization, but the mechanisms underlying this behavior are unknown.

Multi-omics approaches explain the growth-promoting effect of the apocarotenoid growth regulator zaxinone in rice [PDF]
Communications Biology, 2021 Wang et al. report zaxinone as a global regulator of the transcriptome and metabolome, as well as of hormonal and cellular composition of rice roots. This study shows that zaxinone promotes rice growth by enhancing root sugar uptake and metabolism and ...

The apocarotenoid metabolite zaxinone regulates growth and strigolactone biosynthesis in rice [PDF]
Nature Communications, 2019 Strigolactone and abscisic acid are carotenoid-derived plant hormones. Here the authors describe the identification of zaxinone, a further apocarotenoid metabolite, which down-regulates strigolactone content and is required for normal growth and ...

Zaxinone Synthase overexpression modulates rice physiology and metabolism, enhancing nutrient uptake, growth and productivity [PDF]
Plant, Cell and EnvironmentAbstract The rice Zaxinone Synthase (ZAS) gene encodes a carotenoid cleavage dioxygenase (CCD) that forms the apocarotenoid growth regulator zaxinone in vitro. Here, we generated and characterized constitutive ZAS‐overexpressing rice lines, to better understand ZAS role in determining zaxinone content and regulating growth and architecture.
