A novel fluorescent assay for sucrose transporters
Peter J Gora, Anke Reinders, John M Ward Plant Methods 2012, 8:13 (4 April 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Budding yeast is an important model system for the heterologous expression of plant sucrose transporters. The authors have exploited the ability of type I sucrose uptake transporters to transport the fluorescent β-glucoside, esculin, to develop a rapid and sensitive assay system that should be a valuable tool for the functional analysis of members of this sucrose transporter family.

Targeted parallel sequencing of large genetically-defined genomic regions for identifying mutations in Arabidopsis
Kun-hsiang Liu, Matthew McCormack, Jen Sheen Plant Methods 2012, 8:12 (30 March 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Next generation sequencing (NGS) is becoming a powerful tool for identifying mutations at the molecular level. This paper describes an innovation that has the potential to make the NGS approach accessible to many more laboratories. In the targeted parallel sequencing (TPSeq) method only genetically defined genomic regions are sequenced, making the process less expensive and the downstream bioinformatics more straightforward.

Xylem sap collection and extraction methodologies to determine in vivo concentrations of ABA and its bound forms by gas chromatography-mass spectrometry (GC-MS)
Andrew G Netting, Julian C Theobald, Ian C Dodd Plant Methods 2012, 8:11 (22 March 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
The authors describe improved methodology for collecting xylem sap and a novel GC-MS procedure for quantifying the presence of free and bound forms of abscisic acid (ABA). Although the abundance of these bound forms of ABA in tomato is found to be low, the technique will be of particular relevance for those species where bound forms are known to represent a much more significant fraction of the total xylem sap ABA content.

A novel procedure for absolute real-time quantification of gene expression patterns
Yingqing Lu, Lulu Xie, Jiani Chen Plant Methods 2012, 8:9 (9 March 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
Standard methods for quantifying gene transcripts yield relative rather than absolute data (e.g. fold change compared to control treatments). The authors describe a real-time PCR method that enables absolute quantification of cDNAs. The objective is to allow the comparison of gene expression between different tissues, developmental stages, and even different experiments.

Isolation of dimorphic chloroplasts from the single-cell C4 species Bienertia sinuspersici
Shiu-Cheung Lung, Makoto Yanagisawa, Simon DX Chuong Plant Methods 2012, 8:8 (6 March 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
C4-type photosynthesis is of major scientific interest because of its greater efficiency compared to the more common C3-type. Bienertia sinuspersici belongs to a select group of just three terrestrial higher plant species known to perform C4 photosynthesis without the segregation of different parts of the pathway into different cell types. It achieves this feat by partitioning its photosynthetic functions between two distinct types of chloroplast that are located in separate cytoplasmic compartments of the same cell. The authors describe methodology for isolating the two types of chloroplast, providing a means to investigate the biochemistry and physiology that underlies this intriguing photosynthetic system.

Identifying biological landmarks using a novel cell measuring image analysis tool: Cell-o-Tape
Andrew P French, Michael H Wilson, Kim Kenobi, Daniela Dietrich, Ute Voss, Susana Ubeda-Tomas, Tony P Pridmore, Darren M Wells Plant Methods 2012, 8:7 (2 March 2012)
Abstract | Provisional PDF
| PubMed
|
Editor’s summary
Cell-o-tape is a software tool for the analysis of confocal laser scanning microscope images that facilitates the counting and measurement of individual cells along defined cell files. This provides a less subjective alternative to laborious manual quantification of the geometry of plant organs at the cellular scale. As an example, the authors demonstrate how the tool can automate the process of locating the position of the transition zone in an Arabidopsis root.

A rice transient assay system identifies a novel domain in NRR required for interaction with NH1/OsNPR1 and inhibition of NH1-mediated transcriptional activation
Mawsheng Chern, Wei Bai, Wing Hoi Sze-To, Patrick E Canlas, Laura E Bartley, Pamela C Ronald Plant Methods 2012, 8:6 (21 February 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
The authors have developed an improved protoplast-based transient expression assay that provides an efficient way of studying transcription factors and their protein-protein interactions. They have gone on to use the system to identify a novel bipartite protein interaction domain that is conserved in higher plants and that is likely to be important in the regulation of innate immunity to pathogens.

A simple and efficient method for the long-term preservation of plant cell suspension cultures
Anne-Marie Boisson, Elisabeth Gout, Richard Bligny, Corinne Rivasseau Plant Methods 2012, 8:4 (30 January 2012)
Abstract | Full text | PDF | PubMed
|
Editor’s summary
The authors describe a very convenient way to preserve plant cell cultures that doesn't require any specialised equipment and avoids the use of freezing. A combination of low temperature (5oC) and a phosphate-free medium allows the cells to remain viable for 6 months and, importantly to resume active growth without a lag when they are returned to standard culture conditions.
