The phytohormone abscisic acid (ABA) is critical for a range of plant responses to the environment, most importantly in closing the stomata of seed plants during drought (Mittelheuser and Van Steveninck 1969; Brodribb et al. 2014). The high ...

Extraction and Measurement of Abscisic Acid in a Unicellular Red Alga Cyanidioschyzon merolae
Authors:  Yuki Kobayashi and Kan Tanaka, date: 12/05/2016, view: 9412, Q&A: 0
Abscisic acid (ABA) has been known as a phytohormone of land plants, which is synthesized in response to abiotic stresses and induces various physiological responses, but is also found from eukaryotic algae. Recently, we reported that a unicellular ...

Quantifying Auxin Metabolites in Young Root Tissue of Medicago truncatula by Liquid Chromatography Electrospray-ionisation Quadrupole Time-of-flight (LC-ESI-QTOF) Tandem Mass Spectrometry
Authors:  Jason Liang Pin Ng, Thy T. Truong, Charles H. Hocart and Ulrike Mathesius, date: 06/20/2016, view: 8031, Q&A: 0
Auxins represent a major group of phytohormones controlling plant development. The spatio-temporal regulation of auxin gradients is essential for the initiation, growth and correct development of plant organs. Because auxins and their metabolites ...

GC-MS-Based Analysis of Methanol: Chloroform-extracted Fatty Acids from Plant Tissues
Authors:  Manish Kumar Patel, Shubhashis Das and Jitendra Kumar Thakur, date: 09/20/2018, view: 10321, Q&A: 0
Fatty acids (FAs) are carboxylic acids with long aliphatic chains that may be straight, branched and saturated or unsaturated. Most of the naturally occurring plant FAs contains an even number of carbon (C4-C24). FAs are used in food and ...

Investigating the Shape of the Shoot Apical Meristem in Bamboo Using a Superellipse Equation
Authors:  Qiang Wei and Peijian Shi, date: 12/05/2017, view: 4492, Q&A: 0
The shoot apical meristem is the origin of bamboo wood. Its structure and morphology are important for maintaining the normal development of bamboo wood. However, the traditional method to describe the morphology of the shoot apical meristem in ...
