Dr. Mohamed Tawfik, Head of the Oil Crops Biotechnology Lab (OCBL) at the
Agricultural Genetic Engineering Research Institute (AGERI), Giza, Egypt,
discussed the status of developing oil plants in Egypt with Prof. Naglaa
Abdallah, Director of the Egypt Biotechnology Information Center (EBIC)
during an interview.
According to Dr. Tawfik, Egypt's production of vegetable oils is limited and
only covers about 3-5% of its need. Over the past 25 years, vegetable-oil
consumption in Egypt increased from 8.7 kg up to 23.4 kg/ capita. Therefore,
the only way to minimize this gap is by changing the consumer's consumption
pattern and increasing cultivation of oil producing crops via expanding into
new reclaimed arid areas.
"The fact that we are lacking new genotypes of sesame that could be planted
into new reclaimed desert-areas is a major restricting factor, limiting
expansion of sesame cultivation into new lands. We are working on providing
plant breeders with new sesame lines as a new genetic materials based on a
commercial variety which is well adapted to the Egyptian conditions," Dr.
Dr. Tawfik and his research team aimed to minimize yield loss in sesame by
understanding the mechanisms determining seed shattering and engineering
enhanced dehydration stress tolerance in sesame plant. "We are addressing
the enhancement seed-shattering resistance in sesame via understanding the
different genes involved in the maturation, and cell-wall degrading enzymes
of sesame capsules. Several candidates were identified and currently we have
both partial and full-length gene clones of some of the key gene plays; we
are currently in the process of introducing the different constructs into
sesame plants. Also, we are working on enhancement of dehydration-stress
tolerance in sesame by introducing the LOS5 gene, encoding for an ABA
biosynthesis enzyme needed in the last step of ABA biosynthesis in plants.
So far we have 14 overexpressing transgenic lines of sesame and currently,
several T1 lines are being tested and evaluated under greenhouse
conditions," said Dr. Tawfik.
