Crop production provides food, feed, and other nutrients that support our everyday lives. Cereal crops, which include wheat （Triticum aestivurn）, rice （Oryza sativa）, maize （Zea mays）, barley （Hordeum vulgate）, millet （Setaria spp.）, sorghum （Sorghum bicolor）, rye （Secale cereale）, oats （Avena sativa）, and so forth, are the most important source of food for human consumption.

The world population is projected to reach seven billion at the end of year 2011, with an increase of 1 billion from year 2000 to 2011. Currently, Asia alone accounts for about 60% of the world population. China and India together account for over 36%. It will be, undoubtedly, quite challenging to feed the increasing population of the world. On the other hand, the world＇s arable land will not increase and most likely it will reduce due to industrial development and urbanization in developing countries. On the other hand, global warming and climate changes,

In the past decade we witnessed a revolutionary development of wheat genomics and functional genomics, thanks to the development of next generation sequencing (NSG) ***, as one of the most important crops in China and the world and with a huge, repetitive, and polyploid genome,was unconquerable in the past and is now catching up with other crops due to the availability of an increasing number of resources and *** researchers in China have worked unostentatiously during the last decade after The National High Technology Research and Development Program of China first set up the wheat functional genomics program in 2005. Since then many papers on wheat were published in a wide range of international journals demonstrating significant progress in wheat functional genomics.

Breeding to Optimize Chinese Agriculture(OPTICHINA) was a three-year EU–China project launched in June of 2011. As designed, the project acted as a new strategic model to reinforce systematic cooperation on agricultural research between Europe and China. The OPTICHINA International Conference "Breeding to Optimize Agriculture in a Changing World" was held in Beijing, May 26–29, 2014. The conference included six thematic areas:(1) defining and protecting the yield potential of traits and genes;(2) high-throughput precision phenotyping in the field;(3) molecular technologies in modern breeding;(4) plant ideotype;(5) data analysis,data management, and bioinformatics; and(6) national challenges and opportunities for China. The 10 articles collected in this special issue represent key contributions and topics of this conference. This editorial provides a brief introduction to the OPTICHINA project, followed by the main scientific points of articles published in this special issue. Finally, outcomes from a brainstorming discussion at the end of the conference are summarized, representing the authors' opinions on trends in breeding for a changing world.

The improvements of microstructures and properties of a high strength aluminum cast alloy were studied. The effects of rare earth elements on the microstructures and mechanical properties of the high strength cast alloy Al-Cu-Mg-Si were investigated. The result shows that the addition of rare earth elements can change the microstructures in refining the grain size of the alloy and making the needle-like and laminar eutectic Si to a granular Si. With the increase of the rare earth, the tensile strength and elongation of the alloy increase first and then fall down. The mechanical properties of the alloy will reach the highest value when the content of rare earth elements is about 0.7%.
