Meeting Showcases Anti-Sclerotinia Research

A genomic map, disease-resistant beans and other research achievements are being presented January 18-20 during the sixth annual meeting of the National Sclerotinia Initiative, hosted by the Agricultural Research Service (ARS) in Bloomington, Minn.

Sclerotinia is a fungal disease, caused by Sclerotinia sclerotiorum, affecting more than 400 species of broadleaf plants. Since 2002, ARS has led a multistate, multiorganization effort to counterattack the fungus on three fronts: epidemiology; development of resistance in germplasm; and chemical, biological or cultural control.

The initiative aims to protect seven crops that growers across the country are increasingly including in their rotation schemes: sunflowers, soybeans, canola, dry edible beans, chickpeas, lentils and dry peas.

Poor genetic resistance to Sclerotinia in these crops costs up to $280 million annually in degraded quality and reduced yields, notes Larry Chandler, associate director for the ARS Northern Plains Area headquarters in Fort Collins, Colo.

During the meeting, participants from more than 14 universities and 11 trade groups, ranging from the American Soybean Association to the U.S. Dry Bean Council, will discuss the progress to date, as well as identify future research plans and needs through 2009, according to Chandler, the Sclerotinia initiative's ARS coordinator.

Accomplishments to date include development of Sclerotinia risk-assessment maps that dry bean and canola producers can use to implement disease-management strategies; development of dry bean and lentil germplasm lines or cultivars that resist Sclerotinia; uses for the beneficial fungus Coniothyrium minitans as a biological pesticide product; genetically modified soybeans that produce an antifungal peptide against Sclerotinia; and the public release of the sequence for 14,552 of the fungus' genes.

Sclerotinia researchers to search for genes by name, genomic location, their associated proteins and other information.For more details, as well as recent abstracts, visit the National Sclerotinia Initiative web site at: http://www.whitemoldresearch.com/

TITLE: MEETING SHOWCASES ANTI-SCLEROTINIA RESEARCH


ALAM BA NINYO NA PINAGTUUNAN NG PANSIN NG MGA AGRI-EXPERT ANG MGA PAMAMARAAN NA DAPAT GAWIN PARA LABANAN ANG ISANG FUNGAL DISEASE NA TINAGURIANG “SCLEROTINIA”.

ANG SCLEROTINIA AY SANHI NG SCLEROTINIA SCLEROTIORUM. NA NAKAKAAPEKTO SA MAHIGIT 400 SPECIES NG BROADLEAF PLANTS O MGA TANIM NA MERONG MALALAKING DAHON.

SA KATUNAYAN MULA NOONG TAONG 2002 AY TINUTUKAN NA MABUTI NG MGA AGRI EXPERT ANG TINATAWAG NA MULTI-STATE, MULTI-ORGANIZATION EFFORT PARA MA-COUNTER ATTACK ANG NATURANG FUNGUS SA TATLONG PAMAMARAAN: EPIDEMIOLOGY, DEVELOPMENT OF RESISTANCE SA GERMPLASM AT CHEMICAL, BIOLOGICAL O CULTURAL CONTROL.

ANG GANITONG MGA HAKBANG AY NAGLALAYONG BIGYAN NG PROTEKSIYON ANG PITONG URI NG TANIM TULAD NG SUNFLOWERS, SOYBEANS, CANOLA, DRY EDIBLE BEANS, CHICKPEAS, LENTILS AT DRY PEAS.

ANG POOR GENETIC RESISTANACE SA NATURANG URI NG FUNGUS ANG SCLEROTINIA AY NAGIGING SANHI NG PAGKASAYANG NG DAAN-DAANG MILYUNG DOLYAR NG PAGLALAAN NG PONDO BAWAT TAON SA BUONG MUNDO.

SA NGAYON, KABILANG SA MGA HAKBANG NA NAISAKATUPARAN NG MGA EKSPERTO AY ANG RISK ASSESSMENT MAPS NG SCLEROTINIA NA MAAARING MAGAMIT PARA SA DISEASE-MANAGEMENT STRATEGIES; DEVELOPMENT NG DRY BEAN AT LENTIL GERMPLASM LINES O MGA URI NG LUMALABAN SA SCLEROTINIA; MGA GAMIT NITO PARA SA KAIBIGANG FUNGUS NA CONIOTHYRIUM MINITANS BILANG BIOLOGICAL PESTICIDE, MAGING ANG PAGTUKLAS SA GENETICALLY MODIFIED SOYBEANS NA MAAARING MAKAPAG-PRODUCE NG ANTIFUNGAL PEPTIDE LABAN SA SCLEROTINIA.
