1. Rapid PCR-based assay for Sclerotinia sclerotiorum detection on soybean seeds
Caused by Sclerotinia sclerotiorum, white mold is an important seed-transmitted disease of soybean (Glycine max). Incubation-based methods available for the detection and quantification of seed-borne inoculum such as the blotter test, paper roll and Neon-S assay are time-consuming, laborious, and not always sensitive. In this study, we developed and evaluate

2. Supression of seed borne Cladosporium herbarum on common bean seed by Trichoderma harzianum and promotion of seedling development
Trichoderma harzianum isolates have been broadly used for biocontrol of plant diseases caused by fungi. Cladosporium herbarum is a common saprophyte and seed borne fungus, which is easy to manipulate under controlled conditions. It was chosen as a model to test the effectivity of seed treatments with T. harzianum. Common bean seeds (cv. Pérola) contaminated

3. Seed-borne pathogens and electrical conductivity of soybean seeds
Adequate procedures to evaluate seed vigor are important. Regarding the electrical conductivity test (EC), the interference in the test results caused by seed-borne pathogens has not been clarified. This research was carried out to study the influence of Phomopsis sojae (Leh.) and Colletotrichum dematium (Pers. ex Fr.) Grove var. truncata (Schw.) Arx. fungi

6. Trichoderma spp. ON PLANT GROWTH AND BIOCONTROL OF Sclerotinia sclerotiorum AND SEED PATHOGENS OF CARTHAMUS (Carthamus tinctorius) / Trichoderma spp. NO CRESCIMENTO VEGETAL E NO BIOCONTROLE DE Sclerotinia slcerotiorum E DE PATÓGENOS EM SEMENTES DE CÁRTAMO (Carthamus tinctorius)
The cultivation of flowers is, in Brazil, very recent and little known species have a high ornamental potential, Cartamus is such a species and there are cultivars for the production of oil and as well as for ornamental pourposes. Being a recent crop in Brazil, little is known about its associated diseases, specially those that affect the seeds and the soil

7. Effects of some phenolic compounds on soybean seed germination and on seed-borne fungi
Os compostos fenólicos são metabólitos secundários importantes na ecologia vegetal, especialmente em relações alelopáticas e interações com microorganismos, sendo sintetizados principalmente através da via do ácido chiquímico. Neste trabalho, os efeitos de cumarina, ácido ferúlico e naringenina sobre a germinação de sementes de soja e sobre o

8. Hot Acidified Cupric Acetate Soaks for Eradication of Xanthomonas campestris from Crucifer Seeds
Acidified cupric acetate soaks were tested for eradication of Xanthomonas campestris from naturally infected crucifer seeds. The pathogen was eradicated from seeds by soaking in 0.5% cupric acetate dissolved in 0.005 N acetic acid for 20 min at 35, 40, 45, and 50°C but not 25°C. Moreover, normal bacterial flora of crucifer seeds and the seed-borne Phoma li

9. Origin of a Fungal Symbiont of Perennial Ryegrass by Interspecific Hybridization of a Mutualist with the Ryegrass Choke Pathogen, Epichloe Typhina
Seed-borne fungal symbionts (endophytes) provide many cool-season grass species with biological protection from biotic and abiotic stresses. The endophytes are asexual, whereas closely related sexual species of genus Epichloe (Clavicipitales) cause grass choke disease. Perennial ryegrass (Lolium perenne) is a host of two endophyte taxa, LpTG-1 (L. perenne en

10. Evolutionary diversification of fungal endophytes of tall fescue grass by hybridization with Epichloë species.
The mutualistic associations of tall fescue (Festuca arundinacea) with seed-borne fungal symbionts (endophytes) are important for fitness of the grass host and its survival under biotic and abiotic stress. The tall fescue endophytes are asexual relatives of biological species (mating populations) of genus Epichloë (Clavicipitaceae), sexual fungi that cause

11. Purification, Characterization, and Molecular Cloning of the Gene of a Seed-Specific Antimicrobial Protein from Pokeweed1
A small cysteine-rich protein with antimicrobial activity was isolated from pokeweed (Phytolacca americana) seeds and purified to homogeneity. The protein inhibits the growth of several filamentous fungi and gram-positive bacteria. The protein was highly basic, with a pI higher than 10. The entire amino acid sequence of the protein was determined to be homol
