• Two pectic fractions were extracted along the growth gradient of the mung bean hypocotyl. The first one (PF_1) contained pectins soluble in boiling water and characterized by low uronic acids/cations ratio, high esterification degree and high neutral sugars/acidic sugars ratio. The second one (PF_2) contained pectins insoluble in boiling water characterized by high uronic acids/cations ratio, low esterification degree, very low neutral sugar content and a high selectivity for calcium. Water soluble pectins were present in all the wall area whereas the other ones were detected mainly in the middle lamella. The PF_1/PF_2 ratio was high in fast growing tissues but low in mature, slowly growing tissues. The development of the cell wall exchange properties along the growth gradient was related to the changes observed in the PF_1/PF_2 balance.
