Differences in the Anaerobic Lactate-Succinate Production and in the Changes of Cell Sap pH for Plants with High and Low Resistance to Anoxia.
نویسندگان
چکیده
Anaerobically treated seedlings of Oryza sativa L. var arborio accumulated in their shoots more succinate than lactate and cell sap became alkaline. Conversely, in Triticum aestivum L. var MEK 86 lactate accumulation was far higher than that of succinate and cell sap was acidified. Anoxia clearly induced proton consumption in both species as an important means to prevent or counteract acidosis. Other species studied were: Echinochloa crus-galli L. Beauv., Zea mays L. var De Kalb XL75, Secale cereale L. var primizia and Hordeum vulgare L. var rondo. Changes in cell sap pH and succinate to lactate ratios distinguished resistant from nonresistant species.

Background: Root to shoot connection and transfer of information seems to be taken place mostly via the transmissions of signal molecules, secondary metabolites, amino acids, hormones and proteins, through xylem sap. Examination of earlier reports is indicative of relatively high levels of conservation in xylem sap protein compositions. Apparently these protein molecules are be...
