Draft sequence of the rye genome

04.04.2017

Breakthrough for comparative genomics in cereals and genome-based breeding for crop improvement

A team of German plant researchers from the Technical University of Munich (TUM) and from the Leibniz-Institute of Plant Genetics and Crop Plant Research in Gatersleben reports on a whole-genome draft sequence of rye.

This rye whole-genome sequence closes a gap in Triticeae genome research and represents a genome resource of high value for comparative genomics, functional studies and genome-based breeding for sustainable crop production.

Cereal rye (Secale cereale L.) is a diploid Triticeae species closely related to bread wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) and is one of the parents of the man-made cereal Triticale. Due to its superior winter hardiness, rye is especially used in Central and Eastern Europe for food, feed and bioenergy.

Among all diploid Triticeae, rye has the largest and a highly repetitive genome, this means it has a double chromosome set. “For a long time comprehensive whole-genome sequence information of rye has been missing, whereas draft genome sequences of its sister species barley and wheat became available recently”, explains Eva Bauer, scientist at the Chair of Plant Breeding of the Technical University of Munich and main author.

“This gap has now been closed by our publication in The Plant Journal. Through comprehensive resequencing we investigated the exceptional genomic diversity of rye and developed a high-density genotyping array.”

Uwe Scholz, head of the research group Bioinformatics at the Leibniz-Institute of Plant Genetics and Crop Plant research adds: “This genomic resource is an indispensable tool for understanding the biology and evolution of major Triticeae species through comparative genomic approaches and for relating this knowledge to phenotypic traits.“

Rye genome is important for breeding better wheat or barley

Rye is an important model to elucidate the genetic and functional basis of traits that are also relevant for the genetic improvement of wheat and barley. It excels by an exceptional frost tolerance and outyields wheat and barley on poor and medium soils and under drought stress conditions. Rye translocations are present in many wheat varieties grown worldwide, and contribute to abiotic and biotic stress tolerance. Thus, the availability of rye whole-genome sequences will facilitate the elucidation of genes and molecular mechanisms underlying important agronomic traits that are useful for the improvement of related Triticeae species.

The study by IPK and TUM in cooperation with the University of Hohenheim, Helmholtz Zentrum München, the Julius Kühn Institute and KWS Lochow GmbH was funded by the BMBF.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
