Bean Yellow Mosiac Virus In Lupins, Roger Jones Jan 1997

Bean Yellow Mosiac Virus In Lupins, Roger Jones

Journal of the Department of Agriculture, Western Australia, Series 4

Bean yellow mosaic virus (BYMV) is a threat to lupin crops in high rainfall areas of south-western Australia, particularly in districts where subterranean clover pastures are prevalent. The disease causes markedly reduced grain yield in all types of lupins. Worldwide this is the most important virus affecting lupins. The author outlines the symptoms, spread and management of this serious disease.

Field Day 1997, Kansas State University. Agricultural Experiment Station And Cooperative Extension Service

Kansas Agricultural Experiment Station Research Reports

Each Field Day report consists of individual research reports on topics specific to the region, including cultural methods for most of the major crops grown in Kansas, mitigating the effects of weeds, insects, and disease associated with those crops, and irrigation. Research is conducted and reports written by staff of the K-State Research and Extension Southwest Research Extension Center.

Effect Of Media Constituents On In Vitro Culturing Of Cowpea (Vigna Unguiculata) Shoot Tip And Leaf Disk Explants, Mohanjeet S. Brar, Edwin J. Anderson, Teddy E. Morelock, Ronald W. Mcnew Jan 1997

Effect Of Media Constituents On In Vitro Culturing Of Cowpea (Vigna Unguiculata) Shoot Tip And Leaf Disk Explants, Mohanjeet S. Brar, Edwin J. Anderson, Teddy E. Morelock, Ronald W. Mcnew

Journal of the Arkansas Academy of Science

Cowpea is an important legume food crop that is commonly grown in Arkansas and numerous other southern states. The application of biotechnological approaches for the improvement of U.S. cowpea genotypes is currently not possible due to the lack of a regeneration and transformation system. Therefore, the first priority of our research efforts is the development of a plant regeneration system that will facilitate plant transformation studies. In an effort to optimize the media requirements for tissue culturing cowpea, we evaluated the in vitro response of shoot tip and leaf disk explants to various levels of Murashige and Skoog (MS ...


Factors Affecting Transformation Efficiency Of Poplar Hybrid Line Nc5331 By Agrobacterium Tumefaciens, Xin Y. Li, Feng H. Huang, Edward E. Gbur Jr. Jan 1997

Factors Affecting Transformation Efficiency Of Poplar Hybrid Line Nc5331 By Agrobacterium Tumefaciens, Xin Y. Li, Feng H. Huang, Edward E. Gbur Jr.

Journal of the Arkansas Academy of Science

Acetosyringone, pH, and glucose, which may affect Agrobacterium-mediated gene transformation to poplar hybrid line NC5331, were investigated in an attempt to raise the gene transfer efficiency. The Agrobacterium tumefaciens strain used harbored disarmed vector (pMON9749) carrying a bet-glucuronidase gene and a kanamycin resistant marker. With the addition of acetosyringone at 25 to 75 MuM, the transformation efficiency was significantly enhanced, but dependent on pH. Acetosyringone required a pH above 5.8 to achieve an efficient gene transfer and failed to enhance the transformation at lower pH. However, with addition of both acetosyringone and glucose, the transformation was not affected by ...
