Melon's Role in Fruit Genetics

27.06.2011
The melon fruit is an important crop and a model system for studying the genetics of fruit development. Characteristics of melon fruits vary greatly. The purpose of this work was to enhance the study of gene expression during fruit development and ripening of melon fruits, and discover the genes that determine fruit quality traits.

A team of researchers from the Agricultural Research Organization of Israel in collaboration from Evogene, Israel, report a method to obtain high quality ribonucleic acid (RNA). RNA acts as a messenger carrying instructions from DNA responsible for the combination of proteins, which determine traits.

One major factor that determines the precision of this method is the quality of the genetic material used in research. Often, an amplification process is used to obtain the required quantities of genetic material when the source tissue is limited. However, a single round of this process can greatly distort the data.

Non-amplified data was gathered in the reported study to obtain an accurate representation of gene expression during fruit development in the fleshy melon fruit. Nurit Katzir, a researcher from the Agricultural Research Organization of Israel, explained that the results from this study indicate high-quality genetic information for future research can be obtained from mature fleshy fruits. This is significant, as these fruits are notorious for difficulties in accurate genetic extraction.

The data obtained in this study was validated by a comparative amplification process, and is currently being used to identify the genes responsible for traits of melon fruits, such as their development, ripening, and overall quality.

The research was supported by the Office of the Chief Scientist in the Israeli Ministry of Industry, Trade, and Labor through Magnet Program and the Israeli Bio-TOV Consortium. The full article was published in the latest issue of The Plant Genome.

The Crop Science Society of America (CSSA), founded in 1955, is an international scientific society comprised of 6,000+ members with its headquarters in Madison, WI. Members advance the discipline of crop science by acquiring and disseminating information about crop breeding and genetics; crop physiology; crop ecology, management, and quality; seed physiology, production, and technology; turfgrass science; forage and grazinglands; genomics, molecular genetics, and biotechnology; and biomedical and enhanced plants.

CSSA fosters the transfer of knowledge through an array of programs and services, including publications, meetings, career services, and science policy initiatives. For more information, visit www.crops.org

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
