Control of Sodium Transport in Durum Wheat

Control of sodium transport in durum wheat.

In many species, salt sensitivity is associated with the accumulation of sodium (Na(+)) in photosynthetic tissues. Na(+) uptake to leaves involves a series of transport steps and so far very few candidate genes have been implicated in the control of these processes. In this study, Na(+) transport was compared in two varieties of durum wheat (Triticum turgidum) L. subsp. durum known to differ in...

Transport Pathways—Proton Motive Force Interrelationship in Durum Wheat Mitochondria

In durum wheat mitochondria (DWM) the ATP-inhibited plant mitochondrial potassium channel (PmitoK(ATP)) and the plant uncoupling protein (PUCP) are able to strongly reduce the proton motive force (pmf) to control mitochondrial production of reactive oxygen species; under these conditions, mitochondrial carriers lack the driving force for transport and should be inactive. However, unexpectedly, ...

GABA Shunt in Durum Wheat

Plant responses to salinity are complex, especially when combined with other stresses, and involve many changes in gene expression and metabolic fluxes. Until now, plant stress studies have been mainly dealt only with a single stress approach. However, plants exposed to multiple stresses at the same time, a combinatorial approach reflecting real-world scenarios, show tailored responses complete...

The genetic control of the alpha-amylase isozymes of the durum wheat (Triticum durum Desf.).

The hybridological analysis was provided on several durum wheat genotypes with utilizing three F2 populations developed from the crossing between parental forms that differed in the invariable malt-zone triplet on electrophoretic spectrum of alpha-amylase. Three components of this zone are controlled by three genes with an independent way of inheritance: one of them is located on the 6B or 5B c...
