Proton-pumping pyrophosphatase homeolog expression is a dynamic trait in bread wheat ().

Proton-pumping pyrophosphatases (H-PPases) have been shown to enhance biomass and yield. However, to date, there has been little work towards identify genes encoding H-PPases in bread wheat () (s) and limited knowledge on how the expression of these genes varies across different growth stages and tissue types. In this study, the IWGSC database was used to identify two novel genes, and , and elucidate the complete homeolog sequences of the three known genes, bringing the total number of bread wheat s from 9 to 15.

Na(+) transport in glycophytic plants: what we know and would like to know.

Soil salinity decreases the growth rate of plants and can severely limit the productivity of crop plants. The ability to tolerate salinity stress differs widely between species of plants as well as within species. As an important component of salinity tolerance, a better understanding of the mechanisms of Na(+) transport will assist in the development of plants with improved salinity tolerance and, importantly, might lead to increased yields from crop plants growing in challenging environments.
