The Arabidopsis Intracellular Na+/H+ Antiporters NHX5 and NHX6 Are Endosome Associated and Necessary for Plant Growth and Development[w]

摘要

This work demonstrates that two members of the Arabidopsis Na+/H+ antiporter family, NHX5 and NHX6, are critical for normal plant growth and response to stress. Experiments show that the two proteins localize to trafficking endosomal vesicles and demonstrate that NHX5 and NHX6 are required for endosomal trafficking to the vacuole.
