Abstract:
... Fruit color is an important indicator of fruit quality, which is mainly determined by anthocyanin accumulation. Therefore, increasing anthocyanin content is an important way to improve the nutritional and commodity value of fruits. Anthocyanin synthesis is not only regulated by internal genetic factors but also affected by external factors such as light, temperature and nutritional levels, etc. In ...

Abstract:
... MAIN CONCLUSION: The free bases of cytokinins are the biologically active forms of the hormone while cytokinin ribosides become active only upon removal of the ribose residue. Cytokinins (CKs) belong to the classical plant hormones. They were discovered more than 65 years ago, but which molecular forms possess genuine CK activity is still matter of debate. Numerous studies support the view that on ...

Abstract:
... For studying the flower physiology of pitaya plants (Hylocereus sp.), determining the maturity of current shoots is essential. N-(2-Chloro-4-pyridyl)-N′-phenylurea (CPPU), a synthetic cytokinin, functions as a competitive inhibitor of cytokinin oxidase and was used to amplify the function of endogenous cytokinins. Spraying 100 mg•L⁻¹ CPPU on the current shoots of different ages 7.5 weeks after the ...

Abstract:
... ZmTCRR1 and 2 are type-A response regulators expressed in the maize endosperm transfer cells (TC). While type-B response regulators transcriptionally control canonical type-A response regulators, as part of the cytokinin signal transduction mechanism, the ZmTCRRs are regulated by ZmMRP1, a master regulator of TC identity. In addition, the corresponding proteins are not detected in the TC, accumula ...

Notably, mutants with enhanced brassinosteroid (BR) and cytokinin (CK) signaling produce more ovules and have a higher seed number per silique (SNS) than wild‐type plants. Here, we crossed BR‐ and CK‐related mutants to test whether these phytohormones function together in ovule initiation. We determined that simul ...
