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 ...
cytokinins, etc ; bioactive properties; mutants; ribose; Show all 4 Subjects
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:
... Although the molecular regulation of global proliferative arrest (GPA) in arabidopsis (Arabidopsis thaliana) has been studied extensively, the precise role of the different contributors and their interconnections requires further research. A recent contribution by Merelo et al. now provides evidence that repression of cytokinin (CK) signaling affects the promotion of GPA. ...

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 ...

Abstract:
... The efficiency of plant regeneration from explants is influenced by phytohormones and environmental conditions. Light has a particularly marked effect on in vitro shoot regeneration, and some light signaling factors are involved in shoot regeneration, while the underlying molecular mechanism remains elusive. Here, ELONGATED HYPOCOTYL5 (HY5), as the key transcription factor of light signaling, was ...
cytokinins, etc ; auxins; corn; endosperm; epigenetics; genetic factors; glucose; protein secretion; Show all 8 Subjects
Abstract:
... Endosperm transfer cells function as the nutrient transporter, antimicrobic barrier, and signal mediator between filial and maternal tissues. Sugar supply of maternal tissues, sugar demand of filial tissues, and requirement for defence against pathogens are three elemental factors inducing differentiation of endosperm transfer cells. Epigenetic factors, especially MEG1, moderate the key genetic fa ...
cytokinins, etc ; abscisic acid; cell division; corolla; floriculture; flower size; pollinators; Show all 7 Subjects
Abstract:
... MAIN CONCLUSION: Elevated temperatures suppress cell division in developing petunia buds leading to smaller flowers, mediated by ABA. Flower size is one of the most important showy traits in determining pollinator attraction, and a central factor determining the quality of floricultural products. Whereas the adverse effects of elevated temperatures on showy traits have been described in detail, it ...
cytokinins, etc ; abscisic acid; autophagy; brassinosteroids; growth and development; plant growth; Show all 6 Subjects
Abstract:
... Autophagy is a conserved recycling process with important functions in plant growth, development, and stress responses. Phytohormones also play key roles in the regulation of some of the same processes. Increasing evidence indicates that a close relationship exists between autophagy and phytohormone signaling pathways, and the mechanisms of interaction between these pathways have begun to be revea ...

Abstract:
... The role played by phytohormones in insect galls and the mechanisms underlying plant manipulation by gall makers are still unclear. Galls made by Leptocybe invasa on two Eucalyptus species were sampled, the correlations between the levels of nine phytohormones in galls and gall size were analysed, and phytohormone levels in the interior and exterior tissues of galls and L. invasa were determined. ...

Abstract:

In the present document, we report a novel miniaturized dispersive solid-phase extraction based on carbon fibers functionalized with ionic liquid for the determination of multiple-phytohormones and investigation on temporal distribution of phytohormones during the development in strawberry. 1-(3-Aminopropyl)-3-methylimidazolium bromide was modified on the carbon fibers by using covalent functional ...

Abstract:
... The balance between cell proliferation and differentiation into other cell types is crucial for meristem indeterminacy, and both growth aspects are under genetic control. The peptide-receptor signaling module regulates the activity of the cambial stem cells and the differentiation of their derivatives, along with cytokinins and auxin. We identified the genes encoding the signaling module CLE41-PXY ...

Abstract:
... The impact of qDTY12.1 in maintaining yield under drought has not been consistent across genetic backgrounds. We hypothesized that synergism or antagonism with additive‐effect peripheral genes across the background genome either enhances or undermines its full potential. By modeling the transcriptional networks across sibling qDTY12.1‐introgression lines with contrasting yield under drought (LPB = ...

Abstract:
... The interaction between cytokinin, auxin and GA controlled in vitro shoot multiplication in paulownia was influenced by a medium water potential (Ψ) modulation, where it was modulated using different textures or strengths of MS medium, media of different types (MS, WPM, SH and B5) or NaCl incorporation. The interaction between 2 mg/L BAP and 0.1 mg/L NAA expressed the highest shoot number on each ...

Abstract:
... KEY MESSAGE: Senescence-associated transcription factor ATAF2 regulates cytokinin signalling and in vitro shoot multiplication in banana plants. MusaATAF2-like protein is a stress-related NAC transcription factor of banana. It regulates senescence in rooted banana plants. During the early stages of plant development under in vitro conditions, the presence of 6-benzylaminopurine leads to vigorous s ...

Abstract:
... The plant hormone cytokinins (CKs) were generally considered associated with plant development. More recently, functions of CKs in plant stress defense including salt have been increasingly characterized. Under saline conditions, not only CKs homeostasis but also its signal transduction pathway is disturbed in a plant species-dependent manner. In turn, through manipulating exogenous CKs applicatio ...

Abstract:
... Covalent organic framework composites have received great interest and regarded as new-generation porous materials in application of sample preparation. In this work, an agaric-like graphene oxide @ covalent organic framework (AGO@COF) composite was first synthesized and used as an ideal adsorbent for enrichment of trace cytokinins (CKs) due to its large specific surface area, rich in micro-mesopo ...
cytokinins, etc ; Arabidopsis; brassinosteroids; ovules; phenotype; plant hormones; seed yield; siliques; transcription factors; Show all 9 Subjects
Abstract:
... Ovule initiation is a key step that strongly influences ovule number and seed yield. 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 ...

Abstract:
... Shoot branching is an important event of plant development that defines growth and reproduction. The BRANCHED1 gene (BRC1/TB1/FC1) is crucial for this process. Within the phytohormones, cytokinins directly activate axillary buds to promote shoot branching. In addition, strigolactones and auxins inhibit bud outgrowth. This review addresses the involvement of aromatic and isoprenoid cytokinins in sh ...

Abstract:
... Many legume plants form beneficial associations with rhizobial bacteria that are hosted in new plant root organs, nodules, in which atmospheric nitrogen is fixed. This association requires the precise coordination of two separate programs, infection in the epidermis and nodule organogenesis in the cortex. There is extensive literature indicating key roles for plant hormones during nodulation, but ...
