چکیده

We describe a transient dual-luciferase assay combined with a glucocorticoid-inducible system for rice protoplasts. Luciferase genes were efficiently induced by adding 0.1 µM of dexamethasone to the protoplast suspension, the activity of the luciferases reaching a maximum 6 h after induction. This assay system is applicable to studying the translation efficiency of rice by using the luciferase gene harboring tandem copies of an interesting codon at the 5' end.

A new method of defense response analysis using a transient expression system in rice protoplasts.

We established a new plant defense response assay using a transient expression system in rice protoplasts. The assay system sensitively detected defense induction by flagellin, which had previously been assigned to a specific elicitor. Our assay system provides a rapid and efficient way to dissect rice defense mechanisms.

Quantitative analysis by flow cytometry of abscisic acid-inducible gene expression in transiently transformed rice protoplasts.

BACKGROUND Quantifying plant gene expression by flow cytometry (FCM) would allow multidimensional cell-parameter analysis on a per-cell basis, thereby providing insight into the cellular mechanisms of plant gene regulation. Here we sought to establish quantitation by FCM of plant hormone (abscisic acid, ABA)-inducible green fluorescent protein (GFP) expression and to compare the method directly...

Trivalent ions activate abscisic acid-inducible promoters through an ABI1-dependent pathway in rice protoplasts.

The plant hormone abscisic acid (ABA) mediates many vital processes in plant growth and development, including seed dormancy, cell division, water use efficiency, and adaptation to drought, salinity, chilling, pathogen attack, and UV light. Our understanding of ABA signal transduction is fragmentary and would benefit from specific and facile probes of the process. Protoplasts from rice (Oryza s...

Functional characterization and reconstitution of ABA signaling components using transient gene expression in rice protoplasts

The core components of ABA-dependent gene expression signaling have been identified in Arabidopsis and rice. This signaling pathway consists of four major components; group A OsbZIPs, SAPKs, subclass A OsPP2Cs and OsPYL/RCARs in rice. These might be able to make thousands of combinations through interaction networks resulting in diverse signaling responses. We tried to characterize those gene f...

An Optimized Transient Dual Luciferase Assay for Quantifying MicroRNA Directed Repression of Targeted Sequences

Studies investigating the action of small RNAs on computationally predicted target genes require some form of experimental validation. Classical molecular methods of validating microRNA action on target genes are laborious, while approaches that tag predicted target sequences to qualitative reporter genes encounter technical limitations. The aim of this study was to address the challenge of exp...
