Open AccessImproved annotation and quantification of metabolites in rice (Oryza sativa L.) seeds using two-dimensional gas chromatography–time-of-flight mass spectrometry
Two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS) is a powerful tool for identification of compounds in complex samples. Herein, we compared the GC × GC-TOFMS a...

Reciprocal Crosses Between Astaxanthin and Capsanthin Rice Unravel Effects of Metabolic Gene Efficacy in Rice Endosperm
Carotenoids are not naturally accumulated in the endosperms of rice, which is a cereal crop. In our previous study, biofortified rice seeds accumulated two red color carotenoids, ketocarotenoids including asta...

Open AccessMetabolic profiling reveals glucose and fructose accumulation in gcr1 knock-out mutant of Arabidopsis
The ligands and functions of GCR1, the putative G-protein coupled receptor gene of Arabidopsis thaliana, and its role in metabolism are not well studied. Herein, we determined the contents of different pigments, ...

Overexpression of the downward leaf curling (DLC) gene from melon changes leaf morphology by controlling cell size and shape in Arabidopsis leaves
A plant-specific gene was cloned from melon fruit. This gene was named downward leaf curling (CmDLC) based on the phenotype of transgenic Arabidopsis plants overexpressing the gene. This expression level of this ...
