Peanut crop Improvement
The groundnut is a leguminous crop, in which flowering,
self-pollination and fertilization occurs above ground. After
pollination, the base of the ovary, called gynophore, elongates and
carries the ovary, located at its tip, into the soil. A typical peanut
plant produces about 500 flowers throughout the growing season while
only about 40 pods per plant eventually reach the desirable size and
are suitable for harvest. At harvest time, most of the pods are at
different stages of development and are too small for the market. From
the farmer's point of view, this implies that the plant wastes a
considerable amount of energy (organic materials) that went into
non-productive sites. Thus, the aim of this research is to reduce the
number of flowers per plant and to synchronize flower formation. This
will hopefully result in an increase in size of each individual pod.
Sugar Metabolism in Melon Fruits
Fruits belonging to the cucurbits family, like sweet melon,
accumulate the following sugars: stachyose, raffinose
(galactosyl-sucrose oligosaccharides) and sucrose. Any attempt to
improve fruit quality should take into account the metabolic pathways
of sugars during fruit development. In the present study, we
investigate the carbohydrate metabolism in melon fruits. This involves
several enzymes responsible for the accumulation of the above sugars.
Petunia Flowers Development
The plant hormone gibberellins (GAs) are involved in the
regulation of many developmental processes throughout the life cycle of
the plant, including flower development. Several studies have shown
that the developing anthers are the sites of GA biosynthesis in
flowers. We propose that a well-balanced GA signal is required for
normal anther development since many GA mutants are male sterile and
application of exogenous GA to these mutants restores their fertility.
The ability to produce male- sterile flowers has an enormous important
application in production of seeds with known genetic traits. In the
last year we investigated the role of GA in petunia anther development
at the gene level. The aim of this study is to use the petunia flower
as a model for the development of male sterile flowers to be used in
genetic manipulation of seed production.
Effects of Salt Stress on Oil
Accumulation in Citrus Cultures
In plants, oils or fat (triacylglycerols) are stored in oil
bodies called 'oleosomes' in certain tissues, like embryos, or under
stressed conditions. We are using citrus cell culture as a model system
for oil body biosynthesis. This study addresses several aspects of oil
production under stress conditions (salty environment) in order to
understand the possible role of oil bodies in relation to plant
resistance under stressed conditions.
