ABSTRACT SUBMISSION OPEN!

Scientific Posters

Researchers at all levels -- scientists, representatives from industry and government, professors, post-docs, and students -- are encouraged to present a poster at the 12th World Congress of the IAPB. Instructions and guidelines are available on the abstract submission form.

YOU MUST REGISTER FIRST BEFORE SUBMITTING AN ABSTRACT. Registration for the 12th World Congress is open. Each IAPB and SIVB member will receive one free abstract submission as a presenting author. Members who submit more than one abstract as a presenting author will be charged a $100 fee. All non-members will be charged a $100 fee for each abstract submitted.

To be considered as a symposium speaker submit by March 15, 2010. If selected, you agree to a 15-minute presentation in front of an audience and you agree to the date and time of your presentation as determined by the review committee. Travel funds, hotel costs, registration, and/or honorarium are not available. You will be notified after April 1, 2010 if you have been selected.

Deadline to submit poster presentation (and not for consideration as a symposium speaker) and to be included on a searchable abstract flash drive: submit by March 15, 2010.

Poster Presentation Display Information

Poster board size at the meeting will be 3 feet 10 inches (1.17 meters) high by 2 feet, 10 inches (0.86 meters) wide. This is the actual usable space. Poster font size should be no smaller than Times New Roman 12 point.

Presenters can display their posters as early as 4:00 p.m. Sunday, June 6. Posters will be displayed until 5:30 p.m. Thursday, June 10. Posters not removed by 5:30 p.m. Thursday will be disposed of.

All presenters should be near their poster from 5:30 p.m.-7:00 p.m. Monday, June 7. Presenters of even-numbered posters should be near their poster from 5:30 p.m.-7:00 p.m. Tuesday, June 8. Presenters of odd-numbered posters should be near their poster from 5:30 p.m.-7:00 p.m. Wednesday, June 9.

The abstracts and program details will be available for viewing online by May 10, 2010.

Abstract Submission Guidelines for the
12th World Congress of the IAPB

Submission Information:
Only online submission is allowed. Please submit as early as possible to secure space. Poster space availability may depend on the date of abstract submission. If, at a later date, your plans change and you cannot attend the Congress, please inform us so that we may free up poster space for other attendees.

Abstract Distribution/Availability:
During the onsite registration process at America Center, you will receive one flash drive that will contain all accepted abstracts. One flash drive is included as part of your registration fee. Additional flash drives may be purchased following the conclusion of the Congress. You will also receive an abbreviated version of the abstract book to help you navigate through the posters. This abbreviated version will only include the poster number, its title, authors, and institution affiliation(s). No full complete paper copy abstract book will be available unless specially ordered on the registration form for an additional fee of $75.00. All plenary and concurrent lecture abstracts will be placed on the flash drive and will not be available for viewing in the Exhibit Hall.

Please be advised that all accepted abstracts are considered public information and by submitting an abstract you agree to license the IAPB 12th World Congress to include it on the flash drive and/or on the Congress website.

Abstract Instructions:
The �abstract text� section should be one paragraph in length, single-spaced, and limited to a character count (including spaces) of 1,800. In the title, capitalize only the first letter of the first word and any proper nouns, acronyms, etc. Presenting author name should be in all capital letters; all other author names should be in upper and lower case. Abstracts should be carefully prepared, in final form, with no grammatical, typographical, or factual errors. Abstracts should state the specific objective(s) of the study and the results with sufficient detail to support conclusion(s). Do not include any graphics, references, tables, tabular material, the abstract title, author names, or author affiliations in the body of your abstract. Resulting poster abstract should follow the example below:

Rice tungro disease is caused by co-infection by rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV). Disease symptoms are due largely to infection by RTBV, a pararetrovirus. Two rice transcription factors, RF2a and RF2b, which bind to and regulate expression of the RTBV promoter, are important for early plant development, and when down regulated in transgenic plants by expression of antisense genes, the plants exhibit abnormal phenotypes partially reassembling the symptoms of tungro disease. Seedlings of rice cultivar TP309 infected with the RTBV infectious clone (via agro-infiltration) produced typical tungro-like disease symptoms. In contrast transgenic lines with elevated levels of RF2a and RF2b showed essentially no disease symptom under similar conditions. Furthermore, time course studies revealed that the accumulation of RTBV transcripts and RTBV genomic DNA was reduced in transgenic plants at late-stage of infection compared with control plants, and the overall virus titer in transgenic plants is relatively lower in transgenic plants. Similar results were obtained in studies conducted in greenhouse conditions when the viruses were transmitted by green leafhoppers that carried both RTBV and RTSV. As a consequence, disease incidence and severity was reduced in transgenic plants compared with non-transgenic control plants. Other studies confirmed that infection of non-transgenic plants by RTBV did not alter expression of RF2a or RF2b. We will present hypotheses of molecular mechanisms that may explain the role of RF2a and RF2b in development of rice tungro disease and disease resistance.
