Efficient and versatile rapeseed transformation for new breeding technologies
The Plant Journal, Volume 123, Issue 1, July 2025.SUMMARY Many gene functions are widely studied and understood in Arabidopsis; however, the lack of efficient transformation systems often limits the application and verification of this knowledge in crop plants. Brassica napus L., a member of the Brassicaceae family, is usually transformed by Agrobacterium‐mediated hypocotyl transformation, but not all

Gas Chromatographic Determination of Picloram in Fish
Journal of AOAC INTERNATIONAL, 1985 Abstract A simple method for determining picloram in fish is described. The sample is homogenized with ethyl acetate, acidified with IN HC1, and extracted twice more with ethyl acetate. Ethyl acetate fractions are pooled, derivatized with diazomethane, cleaned up by column chromatography, and analyzed by electron capture gas ...

New insights on the structure of the picloram-montmorillonite surface complexes.
Journal of Colloid and Interface Science, 2015 HYPOTHESIS The environmental mobility and bioavailability of Picloram (PCM) are determined by the amine and carboxylate chemical groups interaction with the soils mineral phases. Clay particles, such as montmorillonite (Mt), and the pH value of the media

GLOBAL AND LOCAL REACTIVITY DESCRIPTORS FOR PICLORAM HERBICIDE: A THEORETICAL QUANTUM STUDY
Química Nova, 2015 In this work, we studied the reactivity of picloram in the aqueous phase at the B3LYP/6-311++G(2d,2p) and MP2/6-311++G(2d,2p) levels of theory through global and local reactivity descriptors.
