Genetically modified eggplants (aubergines) shown to be 30% more productive

26.04.2002


Research, published in the online journal, BMC Biotechnology shows how researchers in Italy have used genetically modified eggplants made by the introduction of a gene that increases the level of the plant hormone indole acetic acid (IAA) to produce seedless fruits. Furthermore, these genetically modified eggplants are 30-35% more productive than conventional varieties in both greenhouse and field trials.

The public have a special liking for seedless fruits for two reasons, firstly seeds are often hard and unpalatable and secondly, since seed cavities are filled with fruit tissues instead of seeds, they get more fruit for their money. Consequently there is a great deal of interest in producing seedless fruit in agriculture.

Previous studies have shown that the application of IAA, to flower buds (the part of a plant from which fruits develop) can stimulate the development of fruit in the absence of fertilisation. This technique produces seedless fruit, but it is expensive because of the cost of the IAA and the labour required to treat the flower buds.



The researchers from Italy used genetic engineering to make eggplants produce seedless fruit spontaneously. This was done by inserting a gene, which codes for a molecule involved in the production of IAA that was only “turned on” in the flower buds. It is critical that IAA production was confined to the flower buds as this hormone is involved in a range of different processes in other parts of the plant such as the response of the plant to light and gravity. This specificity was achieved by combining DNA from two genes, one that contained the instructions of how to make the molecule that is needed to manufacture IAA and a second that contained the information that tells the plant to only produce this molecule in the cells located in the flower buds.

The researchers carried out three trials, two of which were conducted in greenhouses and one in an open field site in central Italy. They compared the weight of the eggplant harvest from the genetically engineered plants with eggplants that had not been genetically modified and found increased production of fruit in their genetically modified eggplants in all three trials.

From an economic standpoint the genetically modified eggplants have three major advantages over conventional varieties. Firstly, they produce more fruit with an overall increase in productivity of at least 30-35%. Secondly, the cultivation costs of producing seedless fruit was reduced and finally the genetically modified eggplants could produce fruit in conditions normally considered too cool for fruit production.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
