OBJECTIVE
Shoot elongation of arrowhead tubers (Sagittaria pygmaea Miq.) is stimulated by anoxia, ethylene and CO2. The aim of this study was to characterize anoxic elongation by comparison with elongation stimulated by ethylene and CO2.
METHODS
The effects of the inhibitors aminoethoxyvinylglycine
Development of aerenchyma (soft cortical tissue with large intercellular air spaces) in flooded plants results from cell-wall hydrolysis and eventual cell lysis and is promoted by endogenous ethylene. Despite its adaptive significance, the molecular mechanisms behind aerenchyma development remain
Most persimmon (Diospyros kaki) cultivars are astringent and require postharvest de-astringency treatments such as 95% CO2 (high CO2 treatment) to make them acceptable to consumers. High CO2 treatment can, however, also induce excessive softening, which can be reduced by adding 1-methylcyclopropene
Until recently, the only genes described in plants induced by oxygen deprivation (anoxia or hypoxia) encoded enzymes of glucose-phosphate metabolism. In the present study, two flooding-induced maize (Zea mays L.) genes that may serve a different function have been identified. These genes, with
