Accumulation of Free Proline in Citrus Leaves during Cold Hardening of Young Trees in Controlled Temperature Regimes.

abstract：:Hydrogen-1 nuclear magnetic resonance spectroscopy was used to study water allocation in cell compartments of sun and shade leaves. NMR spectra of Acer platanoides were resolved into two peaks that were assigned to chloroplast and nonchloroplast water. Sun leaves contained 1.7 times more water per unit area of surface...

abstract：:alpha-Amylases are important enzymes for starch degradation in plants. However, it has been a long-running debate as to whether alpha-amylases are localized in plastids where starch is stored. To study the subcellular localization of alpha-amylases in plant cells, a rice (Oryza sativa) alpha-amylase, alphaAmy3, with o...
