    Notes: Abstract The bark of some young woody stems contains storage proteins which are subject to an annual rhythm: they accumulate in the autumn and are mobilized in the spring. We show here that the bark phoem-parenchyma cells of Sambucus nigra L. contain numerous protein bodies, and that the bark lectin (S. nigra agglutinin) which undergoes an annual rhythm is localized in these protein bodies. The protein bodies in the cotyledons of legume seeds also contain lectin, indicating that lectins may be storage compounds themselves or may have a function in storage and-or mobilization processes.

    Notes: Abstract Rice (Oryza sativa, L.) lectin is specifically synthesized during seed formation. It accumulates very rapidly between 8 and 16 days post anthesis and reaches its final content 20 days post anthesis. The rate of synthesis of this protein dramatically increases during the developmental phase coinciding with the rapid lectin accumulation. When the lectin accumulation stops, its rate of synthesis declines rapidly and eventually stops in fully mature embryos. It appears, therefore, that rice lectin is a maturation-specific protein.

    Notes: Summary Each of the three genomes in hexaploid wheat controls the expression of a specific lectin in the embryo. The chromosomes which control their synthesis were determined using nullisomic-tetrasomic and inter-varietal chromosome substitution lines of ‘Chinese Spring’. All three wheat lectins were shown to be controlled by the homoeologous group 1 chromosomes. Using ditelosomic lines of ‘Chinese Spring’ the lectin genes could be localized on the long arms of chromosomes 1A and 1D. Inter-specific addition and substitution lines of Aegilops umbellulata chromosomes to ‘Chinese Spring’ indicated that chromosome 1U, which is homoeologous to the group 1 chromosomes of wheat, controls lectin synthesis.
