Physicochemical Quantification of Abscisic Acid Levels in Plant Tissues with an Added Internal Standard by Ultra-Performance Liquid Chromatography
Author:  Scott A M McAdam, date: 09/20/2015, view: 3051, Q&A: 0
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: 1842, 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: 1906, 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 ...

Olive (Olea europaea L.) is one of the most important oil crops in the Mediterranean basin. Biotechnological improvement of this species is hampered by the recalcitrant nature of olive tissue to regenerate in vitro. In previous ...

Estimation of Silica Cell Silicification Level in Grass Leaves Using in situ Charring Method
Authors:  Santosh Kumar and Rivka Elbaum, date: 11/20/2017, view: 28, Q&A: 0
Silica cells are specialized leaf epidermal cells in grasses with almost the whole cell volume filled with solid silica. In sorghum, silica deposition in silica cells takes place in young, elongating leaves around the mid-length of the leaf. We ...
