Stimulation of glycolysis in anaerobic elongation of pondweed (Potamogeton distinctus) turions.
Stem segments prepared from pondweed (Potamo geton distinctus A. Benn.) turions (overwintering buds) elongate in anaerobic conditions, whereas there is almost no elongation in air. The anaerobic elongation was accompanied by a decrease in dry weights of stem segments, mainly due to consumption of storage starch in the amyloplasts of stem cells. On the other hand, total contents of amino acids i...
متن کاملExpression of sucrose synthase genes involved in enhanced elongation of pondweed (Potamogeton distinctus) turions under anoxia.
BACKGROUND AND AIMS Overwintering buds (turions) of the monocot aquatic pondweed species (Potamogeton distinctus) are highly tolerant to anoxic stress. Sucrose metabolism accompanied by enhanced activity of sucrose synthase (SuSy) operates actively during anaerobic elongation of pondweed turions. The aim of this study is to isolate SuSy genes from the turions and to investigate their transcript...
متن کاملDNA barcoding reveals a new record of Potamogeton distinctus (Potamogetonaceae) and its natural hybrids, Potamogeton distinctus × Potamogeton nodosus and Potamogeton distinctus × Potamogeton wrightii (Potamogeton ×malainoides) from Myanmar
Indo-China floristic region is among the 34 richest floristic regions of the world, and its plant diversity is still under investigation. Here we report a new record of an aquatic plant, Potamogetondistinctus, from Myanmar, a part of the region, that is detected by means of DNA barcoding method. The molecular method further identified the other specimens as hybrids of Potamogeton: one is Potamo...
متن کاملDifferences in the regeneration traits of Potamogeton crispus turions from macrophyte- and phytoplankton-dominated lakes.
Potamogeton crispus is widely used in submerged macrophyte restoration in China. Turions are an important means of reproduction in this species. To compare the regeneration abilities of P. crispus turions in macrophyte- and phytoplankton-dominated lakes, we collected P. crispus turions from a macrophyte-dominated lake (Liangzi Lake) and a phytoplankton-dominated lake (Taihu Lake). Both lakes ar...
