Effects of exogenous proline and glycinebetaine on the salt tolerance of rice cultivars

Biosci Biotechnol Biochem. 2012;76(8):1568-70. doi: 10.1271/bbb.120233. Epub 2012 Aug 7.

Abstract

Salinity significantly increased trisodium-8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS) uptake and decreased the K(+)/Na(+) ratio in salt-sensitive rice (Nipponbare) but did not markedly in salt-tolerant rice (Pokkali). Proline and glycinebetaine (betaine) suppressed the increase in PTS uptake and the decrease in the K(+)/Na(+) ratio in Nipponbare, but did not affect PTS uptake or the K(+)/Na(+) ratio in Pokkali.
