Cell-wall pec­tin and Al resistance

Aluminium (Al) tox­icity is one of the factors lim­it­ing crop pro­duc­tion on acid soils and vari­ous res­ist­ance mech­an­isms have evolved in plant spe­cies. Yang et al. invest­ig­ate gen­o­typic dif­fer­ences in cul­tivars of tatary buck­wheat (Fagopyrum tataricum) and find that an Al exclu­sion mech­an­ism is involved in res­ist­ance. Cell-wall pec­tin con­tent is gen­er­ally lower in Al-resistant than in Al-sensitive cul­tivars, and the degree of methyl­a­tion of the pectins may play an import­ant role in resistance.
