US funding for plant genome research has reached an all time high, according to an article published by Nature Biotechnology. In 2009, the National Science Foundation (NSF) doled out USD 101.6 million to 32 plant genome research projects focusing on "economically important crop plants" ranging from West African cultivated rice to poplar trees. These projects, the NSF said, will better define plant responses to changing environments and contribute to understanding of genetic processes in economically important plants. The project led by the Boyce Thompson Institute for Plant Research/USDA-ARS to complete the sequence of the tomato genome received the largest award, worth more than $10.4 million over four years. 阅读全文 »

Why are Asians drank face is easy to red? Recently, Chinese Academy of Sciences of Kunming Institute of Zoology research team led by Bing Su published research papers in the "BMC Evolutionary Biology" , pointed out that "drinking blush" It may be related to rice cultivation. They believe that the era of domesticated crops such as rice in China has led to changes in the structure of human food and then led to a certain gene mutation, making easy for the so-called "Asian red." 阅读全文 »

A way to save time, money and frustration in searches for specific genes have been found by researchers at Purdue University, It can shed light on the biological processes associated with all forms of life. The work finished by Andrew DeWoody, a professor of genetics, and postdoctoral associate Matthew C. Hale, they have provided evidence that a step called normalization is no longer necessary with recent advances in DNA sequencing technology. Instead, they used a theoretical approach called rarefaction for gene discovery, a process developed for ecological surveys to determine the abundance of a species in an ecosystem. The results were published in the journal BMC Genomics. 阅读全文 »

From the April 10 issue of 《Science》, scientists say in a study that holds clues to the evolution of green plants. Alexandra Worden and colleagues sequenced the genomes of two strains of Micromonas, which are ancient relatives of land plants and are found throughout the world’s oceans. These genomes reveal features of the ancestral algae that launched the billion-year trajectory of plant evolution and the greening of the Earth. 阅读全文 »

Rice is one of the most important plants on earth, because it’s a major food source. Now keeping it safe from disease has become more important. With the completion of Human Genome Project, rice has became a model plant for cereal biology, this give favor for its’ research. A group of three researchers from Iowa State University and one from Kansas State University are looking at two bacterial diseases of rice. 阅读全文 »

Plant biologists have published results of a new study into plant sex in the journal Public Library of Science Genetics (PLoS Genetics), and they discovered that a particular gene switches on ‘the essence of male’. The study identifies role of gene responsible for plant sperm production. 阅读全文 »

Human Genome Project is just a luxury of the banquet, the results of the implementation of the scheme has a huge differenence with originally envisaged. The idea of “Human Genome Project” is relatively simple, for the 20th century estimated the achievements of life sciences is unpractical, especially for DNA sequencing. Some scientists think that as long as the master of the DNA sequence on the grip of the secret of life. However, although the completion of the Human Genome Project was celebrated in April 2003 and sequencing of the human chromosomes is essentially “finished,” the exact number of genes encoded by the genome is still unknown. The results achieved a large gap between it is “anticipate”. 阅读全文 »

Today we will discuss how can biotechnology be applied to agriculture? We have knew What is biotechnology? but it’s general, We need apply to reality. begin with genes. Genes are the pieces of DNA code which regulate all biological processes in living organisms. The entire set of genetic information of an organism is present in every cell. The most significant breakthroughs in agricultural biotechnology are coming from research into the genetic mechanisms behind economically important characteristics and from genomics. 阅读全文 »
