Applying Cutting-Edge Technologies to Better Understand and Accelerate Wheat Improvement
棉花是一种重要的工业作物,逐渐转向在干旱地区种植。然而,参与植物响应各种胁迫的Tubby-like protein,TULP在棉花中很少被报道。本研究通过调节气孔运动,展示了GhTULP30对植物耐受干旱胁迫的改进。GhTULP30在酵母中的异源表达显著提高了其抗盐和干旱耐受性。GhTULP30的过表达使得拟南芥种子在种子萌发期间更加抵御干旱和盐胁迫,并且在干旱胁迫条件下提高了该植物的气孔关闭速度...
该研究发现棉花种植环节的环境影响取决于灌溉、农药和化肥用量。全球约有一半的棉田使用地下水灌溉,农药平均施用量为 1.57 kg/ha,氮磷肥平均投入量为150 kg/ha。全球各棉区灌溉、农药、氮肥施用量差异较大,经济发展水平高的地区施用量较高,而经济水平和水资源有限的棉区施用量较少,亟需因地制宜提高灌溉用水、化肥、农药利用效率,减少生产环节的环境影响。研究还发现,除了棉花种植环节对环境的影响外,...
2023年2月6日,南京农业大学农学院细胞遗传研究所作物遗传与种质创新国家重点实验室小麦遗传育种创新团队在《Molecular Plant》杂志上发表了题为“A chromosome-scale genome assembly of Dasypyrum villosum provides insights into its application as a broad-spectrum disea...
Lecture 4 Rice nutritional improvement by molecular biotechnology by Yuan Dingyang.
栽培陆地棉广泛种植于世界各地,是最重要的天然纤维来源,纤维品质直接决定了其经济价值。国内外棉花育种家开展了广泛的远缘杂交工作,将许多稀有的重要基因转移到栽培陆地棉中提高纤维品质,但并未对这些基因进行深入研究。本研究分析了超过3000份棉花种质资源,总计调查了近80000个纤维品质数据,全面剖析和评估了现存陆地棉种质资源中纤维品质相关的优异位点,并从远缘杂交渐渗系中鉴定到两个新的与纤维品质密切关联的...
In recent years, high quality genome sequences have been obtained for a number of crop species. This tremendous progress has built the foundation for studying the biological functions of the genome an...
Six crucial questions for lucerne breeders are set up and discussed in relation to the available information. (i) Which width of adaptation? Genotype נlocation interaction is region-specific and...
Wheat is an important food crop to mankind. In order to assess the effects of plant breeding on yield and other characteristics of wheat cultivars released by Iran Seed and Plant Improvement Institute...
Five rhodesgrass (Chloris gayana Kunth) cultivars (Asatsuyu, Hatsunatsu, Katambora, Osumi-5, and Osumi-7) were evaluated for forage yield in a 3-year field experiment in the main island of Okinawa loc...
Molecular studies have shown that several genes with various functions are induced by environmental stresses such as drought, high-salinity and low temperature in plants. Most of the dehydration respo...
Since the establishment of the International Rice Research Institute (IRRI) in 1960, IRRI’s breeding effort in varietal improvement for irrigated lowland has passed four decades. Breeding of semi-dwar...
We improved the aluminum borate whisker-mediated method of DNA delivery into rice callus (Oryza sativa L., cv. Notohikari). The following factors were examined: amount of whiskers, the kind of apparat...
Leaf area of sago palm (Metroxylon sagu Rottb.) can not be estimated accurately from the whole leaf shape, and individual leaflet area must be measured for accurate estimation of leaf area. In this st...
