Reproductive follow-up of carriers of familial reciprocal balanced translocations involving chromosome 9 and comparison with predicted outcome

Xylem parenchyma transfer cells were observed in the primary and secondary vascular tissue of stem internodes of 21 in 28 species of grain legumes. Their structural features were similar to those of other transfer cells. The relationships of these cells to transfer cells at nodes were investigated. Non-nodulated seedlings of Phaseolus vulgaris L. formed internode transfer cells if provided mineral nutrients through their roots, but not if grown in distilled water or fed nutrients entirely through their leaves. Wall ingrowths formed in parenchyma of primary xylem of Phaseolus just before full extension of an internode. The significance of this new location for transfer cells was discussed. © 1980 Springer-Verlag.
