Researchers Corn Gene Resistance to Multiple Plant Leaf Diseases
2017/9/1
Alleles that confer multiple disease resistance are valuable in crop improvement though molecular mechanisms underlying their functions remain largely unknown. A quantitative trait locus, qMdr9.02, as...
A Whole-Genome Sequenced Rice Mutant Resource for the Study of Biofuel Feedstocks
Whole-Genome Sequenced Rice Mutant Resource Biofuel Feedstocks
2017/7/24
Rice is a staple food for over half of the world’s population and a model for studies of candidate bioenergy grasses such as sorghum, switchgrass, and Miscanthus. To optimize crops for biofu...
乙酸也可帮助植物耐旱
乙酸 植物耐旱 日本
2017/7/3
日本理化学研究所的一个研究小组近日发现，施加乙酸可增强植物耐干旱的能力，并揭示了其中的机理。迄今为止，主流方法是通过转基因技术来培育耐旱植物，这项新成果有望带来简单、廉价的农业技术，从而可不依赖转基因来减轻干旱灾害的影响。

First Step Toward Epigenetically Modified Cotton
2017/7/21
With prices down and weather patterns unpredictable, these are tough times for America’s cotton farmers, but new research led by Z. Jeffrey Chen at The University of Texas at Austin mi...
A new study in the April 3 issue of Nature Genetics describes an ancestry.com-type adventure that reveals the deep history of a family, including some disreputable relatives. But the family in this ca...
What bothers a plant? Why are some plants rare while others are common? Are the rare plants simply adapted to rare habitat or are they losing the competition for habitat? Are their populations small b...
Over many thousands of years, farmers have bred maize varieties so the crops are optimally adapted to local environments.A new study, published Feb. 6 in Nature Genetics, analyzed close to 4,500 maize...
日本开发出新的DNA解析技术
日本 新的DNA解析技术
2016/10/21
近年来，世界上的“基因标识技术”逐步成熟，有望大幅提升农产品等生物品种改良的效率，但其中DNA解析时间过长、成本较高仍是制约遗传标记技术进入实用化的主要技术难题。作为世界汽车产业和技术创新的领军企业，日本丰田汽车公司（其2016年的年度研发经费达1.7万亿日元，约合1124亿元人民币）从能源安全、环境保护及可持续发展的角度，利用其雄厚的科技创新基础，积极进军生物替代燃料领域，并于最近宣称，已通过“...
What's good for crops not always good for the environment
crops not always good environment
2016/8/1
What's good for crops is not always good for the environment. Nitrogen, a key nutrient for plants, can cause problems when it leaches into water supplies.
Now, scientists have developed a model to ca...
The genome of the corn plant – or maize, as it’s called almost everywhere except the US – “is a lot more exciting” than scientists have previously believed. So says the lead scientist in a new e...
加速新作物培育可抵御气变影响
新作物培育 气变影响
2016/6/23
一个国际团队在最新一期英国《自然·气候变化》上报告说，现有粮食作物产出受气候变化影响在未来10年可能会下降，各国有必要加速培育能更好适应新气候条件的粮食作物品种并尽快开展种植，以确保粮食供应稳定。
开放染色质决定玉米多样性特征
染色质 玉米
2016/5/18
美国研究人员最近发现，仅占玉米基因组1％左右的开放染色质，决定着将近一半的玉米多样性特征。这一发现使科学家能够更容易地开展转基因玉米研究，开发出更耐旱或更高产的玉米品种，从而缓解人类面临的粮食压力。相关研究成果发表在《美国国家科学院院刊》上。
