Salt stress results in a dramatic increase in ABA biosynthesis, H2O2 accumulation, and reduced K+ availability in the shoot. Each of these factors leads to stomata closure, so reducing CO2 assimilation and imposing yield penalties. However, halophytes, naturally salt tolerant plant species, flourish under saline conditions that would cause massive yield penalties in glycophytic crops. Is there anything special about the stomata of halophytes, why is guard cell function in these salt tolerant species not affected by the above factors? This opinion paper addresses these questions by providing a comprehensive assessment of the molecular identity and operational modes of major plasma membrane transporters that mediate stomata movements.
