Scientists Sequence Genome of the Woodland Strawberry, a Model System for Rosaceae Plants

12.01.2010
The genome of a model plant related to peach, cherry and cultivated strawberry has been sequenced by a consortium of international researchers that includes scientists with the Agricultural Research Service (ARS).

The scientists announced the sequencing of the genome of woodland strawberry over the weekend at the Plant and Animal Genome Conference in San Diego, Ca. The project was funded by Roche Diagnostics.

Fragaria vesca, commonly known as the woodland or alpine strawberry, is a member of the Rosaceae family, which consists of more than 100 genera and 3,000 species. This large family includes many economically important and popular fruit, nut, ornamental and woody crops, such as almond, apple, peach, cherry, raspberry, strawberry and rose.

F. vesca has many traits that make it an attractive model system for functional genomics studies. Its small size and rapid life cycle enable researchers to conduct genetic analyses with great efficiency and low cost. To determine the importance of a gene of interest, F. vesca can be transformed in order to modulate the activity of that gene in the plant. Most importantly, F. vesca has a relatively small genome, yet shares most gene sequences with other members of the Rosaceae family, making it an important tool for addressing questions regarding gene function.

ARS molecular biologist Janet Slovin, with the Genetic Improvement of Fruits and Vegetables Laboratory in Beltsville, Md., created the nearly inbred line used in the F. vesca genome sequencing project. Named “Hawaii 4,” this line allowed the researchers to more easily program a computer to piece the genome together from the relatively short lengths of sequence data generated by modern sequencing machines.

Although the F. vesca genome is a model genome for the Rosaceae group, critical regulatory gene functions will probably differ, hypothesizes Slovin. Scientists can use the genome sequence to identify these genes, to test their function in F. vesca, and to develop molecular genetic markers for more rapid breeding of crops belonging to the Rosaceae group. Slovin will use the genome to study and improve heat tolerance during fruit production in strawberry.

ARS is the principal intramural scientific research agency of the U.S. Department of Agriculture. The research supports the USDA priorities of promoting international food security and responding to climate change.

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...

Im Focus: AchemAsia 2019 will take place in Shanghai

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...
