Greek Key Motif

Made-up of beta-sheets

Four adjacent antiparallel strands linked by loops

Three anti-parallel beta sheets are connected 3 loops

The pattern is similar to ornamental pattern used I ancient Greece, therefore called as Greek Key motif

ABA causes stomata to close by reversing the accumulation of potassium salts in guard cells and inducing the conversion of sugars into starch. 

The resulting fall in solute concentration leads to loss of water from the guard cell into the apoplast by osmosis, a fall in guard cell turgor, and closing of the stomatal pore.
