Callus Development and Organogenesis in Cultured Explants of Cowpea (Vigna unguiculata (L.) Walp

Description: Cowpea, Vigna unguiculata (L.) Walp is an excellent source of protein, vitamins and minerals and a major food crop many parts of Africa. Optimal production levels are hampered by insect pests and diseases. Biotechnological techniques such as tissue culture and genetic engineering can aid in the development of varieties with resistance to insect pests and diseases. The objective of this study was to investigate conditions necessary for the development of a reproducible tissue culture system that can be applied to regenerate transformed cells from culture. The in vitro manipulation of cowpea using Murashige and Skoog (MS) medium, auxins and cytokinins resulted in the formation of callus and rhizogenesis. Calli that were formed were separated into six classes based on color and texture. Yellowish friable callus, yellowish compact, soft yellowish callus and green and white were composed of largely vacuolated cells and were non-regenerative. Friable green callus was the most prevalent callus type and could form of roots in some hormone combinations. Green spots were formed on hard compact green callus. The green spots became nodular, forming root primordia and ultimately giving rise to roots. None of the six calli types gave rise to the formation of shoots. Embryogenic callus was induced from cowpea explants cultured on MS medium supplemented with dicamba and picloram. Embryogenic suspension cultures were initiated from callus induced on MS supplemented with 3.0 mg/L dicamba or picloram and conditions for maintenance of embryogenic suspension cultures were evaluated. Somatic embryos were formed in suspension cultures. Attempts to convert and germinate the somatic embryos resulted in the formation of callus or formation of appendages on the somatic embryos or in the death of the embryos. The appendages formed roots on prolonged culture. Further research is needed to determine appropriate optimal conditions for embryo conversion and germination and ultimately plant ...

The Control of the Root-Knot

Description: "Attention should be directed to the continual spread of a common disease of plants generally known under the names of root-knot, root-gall, big-root, etc. It occurs as an out-of-doors pest in all except the most northern Sates, but it is most abundant in the South and Southwest and is everywhere prevalent in greenhouses. It is the cause of serious damage to many crops. The extent of this damage is difficult to estimate, since it is both direct and indirect and in many cases is overlooked entirely. The direct damage is that caused to the growing crops. The indirect damage results from the fact that the presence of the disease makes it impracticable to grow certain crops." -- title page

Laser Ablation Inductively Coupled Plasma Mass Spectrometry and Raman Spectroscopy Imaging of Biological Tissues

Description: Laser Ablation Inductively coupled plasma mass spectrometry (LA-ICP-MS) and Raman spectroscopy are both powerful imaging techniques. Their applications are numerous and extremely potential in the field of biology. In order to improve upon LA-ICP-MS an in-house built cold cell was developed and its effectiveness studied by imaging Brassica napus seeds. To further apply LA-ICP-MS and Raman imaging to the field of entomology a prong gilled mayfly (Ephemeroptera: Leptophlebiidae) from the Róbalo River, located on Navarino Island in Chile, was studied. Analysis of both samples showcased LA-ICP-MS and Raman spectroscopy as effective instruments for imaging trace elements and larger molecules in biological samples respectively.

Survey of protected vascular plants on the Oak Ridge Reservation, Oak Ridge, Tennessee

Description: Vascular plant surveys were initiated during fiscal year 1992 by the environmentally sensitive areas program to determine the baseline condition of threatened and endangered (T&E) vascular plant species on the Oak Ridge Reservation (ORR). T&E species receive protection under federal and state regulations. In addition, the National Environmental Policy Act (NEPA) requires that federally-funded projects avoid or mitigate impacts to listed species. T&E plant species found on or near the U.S. Department of Energy`s (DOE) Oak Ridge Reservation (ORR) are identified. Twenty-eight species identified on the ORR are listed by the Tennessee Department of Environment and Conservation as either endangered, threatened, or of special concern. Four of these have been under review by the U.S. Fish and Wildlife Service for possible listing (listed in the formerly-used C2 candidate category). Additional species listed by the state occur near and may be present on the ORR. A range of habitats support the rare taxa on the ORR: river bluffs, sinkholes, calcareous barrens, wetlands, utility corridors, and forests. The list of T&E plant species and their locations on the ORR should be considered provisional because the entire ORR has not been surveyed, and state and federal status of all species continues to be updated. The purpose of this document is to present information on the listed T&E plant species currently known to occur on the ORR as well as listed species potentially occurring on the ORR based on geographic range and habitat availability. For the purpose of this report, {open_quotes}T&E species{close_quotes} include all federal- and state-listed species, including candidates for listing, and species of special concern. Consideration of T&E plant habitats is an important component of resource management and land-use planning; protection of rare species in their natural habitat is the best method of ensuring their long-term survival.

STI. DE-FG02-00ER1505 [Brief summary of 11th International Conference on Arabidopsis Research]

Description: The 11th International Conference on Arabidopsis Research was held in Madison, Wisconsin, June 24 through June 28, 2000. Arabidopsis thaliana has been the subject of genetic study for many years. However, during the last decade, the number of research laboratories using Arabidopsis as a model system has increased tremendously, and Arabidopsis is currently being used to study all aspects of plant biology. The rapid rate of progress in Arabidopsis research, including the completion of the genomic sequence, underscores the usefulness of holding a meeting every year. These conferences provide an important opportunity for the Arabidopsis community to interact and exchange information. The meeting opened with an evening keynote address on the global impact of plant biology, delivered by Richard Jefferson, the Executive Director of CAMBIA (Center for the Application of Molecular Biology to International Agriculture). This was followed by short updates from each of the NSF-funded Plant Genome groups. Many of these groups are carrying out projects that impact the Arabidopsis community. Each of the 17 platform sessions consisted of talks from two invited speakers followed by two short talks that were chosen from the submitted poster abstracts. A concerted effort was made to invite junior investigators, including graduate students and postdocs, to give these talks. Posters were available for viewing during three formal sessions, and, because the poster session was adjacent to the lecture hall, it was easy for participants to go back and forth between posters and lectures. Finally, a mixer and an informal banquet provided opportunities for participants to meet new people and renew acquaintances. Furthermore, the registration package included all lunches and dinners together in a cafeteria next to the posters and lecture hall, thus encouraging the meeting of established investigators with students and postdocs. The North American Arabidopsis Steering Committee (elected by electronic ballot by ...

Minority Summer Research Program in the Plant Sciences

Description: Gutierrez and Larcom (2000) suggest that ''According to the National Science Foundation/Division of Science Resources Studies in 1997, the percentage distribution of scientists and engineers in the labor force by race/ethnicity changed little between 1993 and 1997''. According to this report, Black, non-Hispanic went from 3.6 in 1993 to 3.4 in 1997. Hispanic went from 3.0 in 1993 to 3.1 in 1997; and American Indian/Alaskan Native stayed the same at 0.3 during the same period. The only exceptions were a slight increase in the percentage of Asian from 9.2 in 1993 to 10.4 in 1997, while a slight decrease in percentage White from 83.9 in 1993 to 82.8 in 1997. Overall, no major changes in minorities were present in the science and engineering fields during that period. These data shows that major efforts are needed in order to improve and achieve better results for diversity in the workplace (Gutierrez & Larcom, 2000). This does not mean that major steps have not been taken over this period. For example, the Minority Summer Research Program in Plant Sciences (also funded in part by NSF under the title, ''Undergraduate Researchers in Plant Sciences Program'') was established in an effort to enhance the diversity of the plant science community. The Minority Summer Research Program in Plant Sciences was designed to encourage members of underrepresented groups to seek career opportunities in the plant sciences. To achieve this end, the program contained several components with the primary focus on mentored research for undergraduate students. The research experience was provided during the summer months on the campus of Michigan State University in East Lansing, Michigan. At the end of the summer experience, each participant presented an oral report on their research, and submitted a written paper on the same topic. This was deliberately designed to mimic the ...
