Research on grey mould offers possible breakthrough in tomato cultivation

Tomato growers are likely to soon be able to cultivate new tomato varieties without having to use pesticides against grey mould (Botrytis cinerea). This is the conclusion of the STW-sponsored thesis by Richard Finkers from Wageningen University, with which he hopes to earn his doctorate on 3 April 2007. Finkers designed highly efficient methods whereby tomato varieties can be resistant to grey mould. The leading company De Ruiter Seeds is already applying these methods in its breeding programme.

Finkers started off with wild tomato accessions that were resistant to grey mould. When crossing the resistant wild tomato Solanum habrochaites LYC4 with the susceptible S. lycopersicum cv. Moneymaker, he identified two areas with resistant genes in the DNA.

This, however, did not explain all the variations in resistance. With this in mind, Finkers next made a step-by-step scan of the entire genome of the wild tomato to identify locations that have an effect on resistance. Ten areas were found that accommodated resistance factors against grey mould. DNA-markers were then developed for each area to be able to track the presence of each resistance factor in breeding programmes.

With help of the DNA-markers, the identified areas can now be intentionally introgressed in the breeding programmes of De Ruiter Seeds, a Dutch company with a global reputation in the field. Using the DNA-markers, it expects to market new tomatoes that are resistant to grey mould in the near future. The new varieties will mean tomato growers will have to devote far less resources – or perhaps none at all – to combating B. cinerea.

An additional benefit of these new tomatoes is that they will be more suitable for closed glasshouse cultivation. This new type of glasshouse has a higher atmospheric humidity that actually increases the chance of grey mould activity. By providing tomato varieties resistant to grey mould, De Ruiter Seeds will fill a worldwide need that has long been around.

The research was partly financed by STW (the Technology and Sciences Association) and De Ruiter Seeds. As the developed knowledge obtained from this research has been patented, and therefore both protected and made accessible.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
