This new advance involves, after sequencing other plants’ genomes such as the sample species in biological research Arabidopsis thaliana, rice, poplar and vine, the fifth vegetal genome sequenced up to now, and the first one from a fruit tree. Besides, the authors have used in their analysis the SunUp transgenic variety, virus ringspot resistant (which represents a serious threat for this species), which means that this has been the first transgenic organism to be sequenced.
Rafael Navajas Pérez, researcher of the Department of Genetics of the University of Granada, is part of the team made up by more than 85 scientists who have participated in this research supervised by doctors Ray Ming (University of Illinois), Andrew H. Paterson (University of Georgia) and Maqsudul Alam (University of Hawaii).
Papaya is a very important crop in great part of Latin America and the USA owing to its nutritional benefits and medical applications, and provides an annual income of about 130 million dollars only in the state of Hawaii. In Europe, this crop is experiencing a boom, and Spain, and specifically the Tropical Coast of Granada, is an important producer as a consequence of the particular climatic conditions of the area.
From this discovery, the researchers have already identified that its genome contains fewer genes than that of the Arabidopsis (a small annual herb), in spite of being three times bigger than it. According to the researcher from Granada, the lack of recent phenomenon of gene duplication, frequent in angiosperms genomes, can be behind of this observation. Despite this, it has been detected a significant increase in the number of genes related to arboreal development, the deposition and removal of starch reserves, the attraction of agents responsible for spreading the seeds and the adaptation to the length of the day in a tropical climate.Other important crops
Dr Navajas Pérez, who at present is working on the sequencing of the determinant region of the sex in the sexual chromosomes of papaya and whose research career has been focused on different aspects of plants’ sexual determination, intends, in a near future, to implement a research work in the UGR directed to sex early diagnosis in vegetal species of economic interest for Andalusia, as well as for the study of other molecular aspects of sex Biology in plants.Reference: Rafael Navajas Pérez.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
