El patron de distribucion de la C(14)-malformina en porciones de plantulas de Phaseolus vulgaris L. cambio durante el tratamiento con agua en ausencia de malformina. A partir de estos cambios y mediante la comparacion con los patrones de distribucion de C(14) en la base y en la parte superior de las plantulas, se concluyo que algo de C(14)-malformina penetra en la celula y prosigue hacia la pared celular mediante compuestos intermedios. Se sugirio como una hipotesis de trabajo, que en las raices primero aparece la C(14)- malformina como una fraccion soluble "pequenas moleculas", se une a una fraccion soluble de proteina y avanzada por la fraccion lipida de la pared hacia la pared propiamente dicha. Nada impidio el enlazamiento directo de parte de la C(14)-malformina a la fraccion de la pared. En las hojas, la ruta de la C(14)-malformina hacia la pared celular, fue algo semejante en ciertos aspectos a la observada en las raices. (RA-CIAT) spa
The distribution pattern of (14)C-malformin in major fractions of Phaseolus vulgaris L. seedlings shifted during water treatment in the absence of malformin. From these shifts and by comparison of the (14)C distribution patterns at the base and top of the seedlings, it was concluded that some (14)C-malformin enters the cell and proceeds to the cell wall via intermediate compounds. As a working hypothesis it was suggested that in roots (14)C-malformin first appears in a soluble "small molecules" fraction, binds to a soluble protein fraction and proceeds via the wall lipid fraction to the wall itself. Direct binding of some (14)C-malformin to the wall fraction was not precluded. In leaves the pathway of (14)C- malformin to the cell wall was similar in some respects to that in roots. (AS) eng
