SUMMARY OF PhD THESIS
-------------------------------------

TITLE: Genetic improvement of soybean seed quality (Glycine max (L. )
merr. ): lipoxygenases, and proteins and response to nitrogen nutrition.
------------------------------------------------------------------------

SUMMARIZES: The use of soybean seed in human foods can be favored by a
reduction of the lipoxygenase content. This investigation aim to analyze
the variability and the genetic determinism of lipoxygenase and proteins
seed contents. The study of lipoxygenase activity, determined
polarographically on seeds taken from plants grown under controlled
conditions with a mineral or symbiotique nitrogen feeding, shows a large
genotypique variability for lipoxygenases contents, enhanced by high
dinitrogen fixation. In these same conditions of culture, during the seed
filling period, lipoxygenases accumulation appears massive until the
physiological maturity stage (R7) and is followed by a partial
degradation. The lipoxygenases may play a role in the temporary storage
of nitrogen. Finally a genetic study is realized in natural conditions
and in pots, with a complete diallel between five genotypes,
representative of a great variability for soluble proteins and
lipoxygenases seed contents. Hybrids F1 show a strong effect of heterosis
for soluble proteins, lipoxygenase 1 and total lipoxygenases contents.
For these last, hybrids show a strong homeostatique behavior with weaker
contents than those of the parents. Though, values of contents in soluble
proteins indicate a positive overdominance as well as a great sensitivity
to environnementales variations. Genetic determinism of the expression of
soluble proteins and lipoxygenases contents appears complex and linked to
significants additive, non-additive and reciprocal effects. Thus, the
reduction of lipoxygenases contents and the improvement of proteins
contents can be considered on a genetic context implying the nuclear and
cytoplasmique genomes together with more efficent dinitrogen fixation,
with respect of dinitrogen fixation
