Current Understanding of Role of Vesicular Transport in Salt Secretion by Salt Glands in Recretohalophytes
Soil salinization is a serious and growing problem around the world. Some plants, recognized as the recretohalophytes, can normally grow on saline–alkali soil without adverse effects by secreting excessive salt out of the body. The elucidation of the salt secretion process is of great significance f...
