Rice tillering is an important agronomic trait affecting grain ***,we identified a high-tillering mutant tillering20(t20),which could be restored to the wild type by treatment with the strigolactone(SL)analog rac-GR24.T20 encodes a chloroplast ζ-carotene isomerase(Z-ISO),which is involved in the biosynthesis of ca-rotenoids and their metabolites,SL and abscisic acid(ABA).The t20 mutant has reduced SL and ABA,raising the question of how SL and ABA biosynthesis is coordinated,and whether they have overlapping functions in *** discovered that rac-GR24 stimulated T20 expression and enhanced all-trans-p-carotene ***,rac-GR24 also stimulated expression of Oryza sativa 9-CIS-EPOXY-CAROTENOID DIOXYGENASE 1(OsNCED1)through induction of Oryza sativa HOMEOBOX12(0sHOX12),promoting ABA biosynthesis in shoot *** the other hand,ABA treatment significantly repressed SL biosynthesis and the ABA biosynthetic mutants displayed elevated SL *** treatment reduced the number of basal tillers in both t20 and wild-type ***,while ABA-deficient mu-tants aba1 and aba2 had the same number of basal tillers as wild type,they had more unproductive upper tillers at *** work demonstrates complex interactions in the biosynthesis of carotenoid,SLs and ABA,and reveals a role for ABA in the regulation of rice tillering.

Optimal Design of a Photovoltaic Hydrogen Production System ...

Amperometric Biosensors Sensitive to Organic Peroxides Based on Immobilization of Redox Organic Dyes and Horseradish Peroxidase in Polyester Ionomer Film

第35届中国过程控制会议

This paper presents a mathematical model for a photovoltaic hydrogen production system, along with an optimal design study applied to this system. Precise modeling of hydrogen production has proven to be a challenging task. Based on previous work, a general framework is proposed for battery pack-assisted photovoltaic hydrogen production. Specifically, explicit mathematical expressions are given for the hydrogen production efficiency of the electrolyzer, and a current source model is established for the photovoltaic panels. Regarding the optimal design, a systematic framework is outlined to obtain the optimal strategy by converting the control problem into a boundary value problem, subsequently solved via nonlinear programming. Simulation results show that under the optimal strategy, the battery energy consumption by the photovoltaic hydrogen production system is significantly reduced, while maintaining minimal power consumption operation when the irradiation is insufficient, without the need for frequent start-stop cycles. In addition, the calculation time of the IPOPT solver to find the optimal strategy is discussed, proving its ability to address nonlinear planning problems at a millisecond-level calculation time.

Simple and effective organic biosensors sensitive to organic peroxides such as 2 butanone per oxide and tertbutyl hydroperoxide are constructed by immobilizing a series of redox organic dyes and horseradish peroxidase in Eastman AQ polymer film. The organic dyes are methylene blue, methylene green, meldola blue, new methylene blue N and N methyl phenazine methosulphate. The biosensors display high sensitivity and fast response to tertbutyl hydroperoxide and 2 butanone peroxide because of high efficiency of electron transfer between immobilized horseradish peroxidase and the electrode via the redox organic dyes. The comparison of the biosensors employing different organic dyes is made in formal potential, linear range and response time.
