Soybean Cyst Nematode
The soybean cyst nematode (SCN), ''Heterodera glycines'', is the most devastating pest to soybean crop yields in the U.S., targeting the roots of soybean and other legume plants. When infection is severe SCNs cause stunting, yellowing, impaired canopy development, and yield loss. The symptoms caused by SCNs can go easily unrecognized by farmers—in some cases there are no warning symptoms before a loss of 30% of the yield.“You can literally have 40% yield loss with no symptoms,” says Greg Tylka, Iowa State University (ISU) Extension nematologist. Due to the slight stunting and yellowing, many farmers may mistake these symptoms as environmental problems when in fact they are SCNs. Another symptom of SCNs that may affect farmers' yields is stunted roots with fewer nitrogen-fixing nodules. Due to the fact that soybean cyst nematodes can only move a few centimeters in the soil by themselves, they mostly are spread via tillage or plant transplants. This area of infection will look ...

Crop Science (journal)
''Crop Science'' is a bimonthly peer-reviewed scientific journal covering agronomy. It was established in 1961 by founding editor-in-chief H.L. Hamilton and is published by ACSESS (Alliance of Crop, Soil, and Environmental Science Societies) in partnership with Wiley. It is the official journal of the Crop Science Society of America. Since 2013, it is available online only. ''Crop Science'' is the originator of two spin-off journals, '' The Plant Genome'' and the ''Journal of Plant Registrations''. The former was published as a supplement to ''Crop Science'' from 2006-2008, and launched as a separate open access journal later that year. The ''Journal of Plant Registrations'' was established as a separate journal in 2007, featuring an expanded format for crop registrations describing newly developed plant varieties, parental lines, germplasms, genetic stocks, and populations. As with most other professional scientific journals, papers undergo an initial screening by the editor, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heterodera
''Heterodera'' is a genus of nematodes in the family Heteroderidae. Members of the genus are obligate parasites and different species attack different crops, often causing great economic damage. The genus is unique among nematode genera because of the ability of the female to transform into a tough, brown, cyst which protects the eggs which have been formed within her body. The name heterodera "refers to the different 'skins' of female and cyst."Tylenchida: Parasites of Plants and Insects, 2nd ed., by Mohammad Rafiq Siddiqi Diversity The following is a list of taxa in the genus ''Heterodera'': * ''Heterodera amygdali'' * '' Heterodera arenaria'' * '' Heterodera aucklandica'' * ''Heterodera avenae'' * '' Heterodera bergeniae'' * ''Heterodera bifenestra'' * '' Heterodera cacti'' * ''Heterodera cajani'' * '' Heterodera canadensis'' * '' Heterodera cardiolata'' * ''Heterodera carotae'' * '' Heterodera ciceri'' * ''Heterodera cruciferae'' * ''Heterodera delvii'' * '' Heterodera elachis ...

Root Cyst Nematode Infection
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Anatomy Root morphology is divided into four zones: the root cap, the apical meristem, the elongation zone, and the hair. The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubrication. The apical meristem behind the root cap produces new root cells that elongate. Then, root hairs form that absorb water and mineral nutrients from the soil. The first root in seed producing plants is the r ...

Genome Mapping
Gene mapping describes the methods used to identify the locus of a gene and the distances between genes. Gene mapping can also describe the distances between different sites within a gene. The essence of all genome mapping is to place a collection of molecular markers onto their respective positions on the genome. Molecular markers come in all forms. Genes can be viewed as one special type of genetic markers in the construction of genome maps, and mapped the same way as any other markers. In some areas of study, gene mapping contributes to the creation of new recombinants within an organism. Genetic vs physical There are two distinctive types of "maps" used in the field of genome mapping: genetic maps and physical maps. While both maps are a collection of genetic markers and gene loci, genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs. While the physical map cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
