    Abstract Invertase (INV), a key enzyme in sucrose metabolism, irreversibly catalyzes the hydrolysis of sucrose to glucose and fructose, thus playing important roles in plant growth, development, and biotic and abiotic stress responses. In this study, we identified 27 members of the BnaINV family in Brassica napus. We constructed a phylogenetic tree of the family and predicted the gene structures, conserved motifs, cis-acting elements in promoters, physicochemical properties of encoded proteins, and chromosomal distribution of the BnaINVs. We also analyzed the expression of the BnaINVs in different tissues and developmental stages in the B. napus cultivar Zhongshuang 11 using qRT-PCR. In… More >

    Records of Sclerotinia minor infecting cultivated and invasive plants in the southern Pampas and northern Patagonia, Argentina, including comparative studies with Sclerotinia sclerotiorum

    Kiehr M1, R Delhey1, J Lusto2, PJ Paoloni3

    Phyton-International Journal of Experimental Botany, Vol.79, pp. 199-202, 2010, DOI:10.32604/phyton.2010.79.199

    Abstract A report is given on host plants, distribution, damage and importance of Sclerotinia minor in the southern Pampas and northern Patagonia regions (Argentina). Spontaneous infections were recorded on seven plant species. Sonchus oleraceus and Eruca vesicaria are new hosts for S. minor; Cichorium intybus and Zinnia elegans are new hosts for Argentina. This fungus causes important damage on Helianthus annuus and Lactuca sativa, and it occasionally affects C. intybus and Solanum lycopersicum. Comparative in vitro and in planta studies were carried out with S. minor and S. sclerotiorum isolates obtained from sunflower. More >

    Sclerotinia sclerotiorum infecting cultivated and invasive plants in the southern Pampas and northern Patagonia, Argentina

    Delhey R1, M Kiehr1, MI Allievi1, J Lusto2, S Frayssinet1, B Sidoti Hartmann3, I Kröger1, PJ Paoloni4, D Zappacosta1, A Servera3

    Phyton-International Journal of Experimental Botany, Vol.78, pp. 111-115, 2009, DOI:10.32604/phyton.2009.78.111

    Abstract A report is given on plant hosts, distribution, damage and importance of Sclerotinia sclerotiorum in the southern Pampas region and northern Patagonia (Argentina). Spontaneous infections were recorded on 25 plant species, including oil crops, vegetables, and ornamental and invasive plants. Carduus thoermeri, Xanthium cavanillesii, Marrubium vulgare and Ranunculus repens are new hosts of S. sclerotiorum. The records on Helianthus tuberosus, Diplotaxis tenuifolia and Cucurbita pepo are new to Argentina. Sclerotinia sclerotiorum causes important damage on Helianthus annuus, Glycine max, Apium graveolens, Foeniculum vulgare and Lactuca sativa. S. sclerotiorum is also reported on Daucus carota, Petroselinum crispum, Brassica oleracea, B. rapa… More >

    In vitro antifungal/fungistatic activity of manganese phosphite against soybean soil-borne pathogens

    Carmona MA1, E Simonetti2,3, ME Ravotti1, MM Sc,iani4, AG Luque4, NA Formento5, FJ Sautua1

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 265-269, 2017, DOI:10.32604/phyton.2017.86.265

    Abstract Soybean root and stem rots caused by soil-borne pathogens are diseases commonly found in soybean fields, and one of the most important causes of crop losses. In the present study, the mycelial sensitivity of Fusarium virguliforme, F. tucumaniae, Sclerotinia sclerotiorum and Macrophomina phaseolina was evaluated on potato dextrose agar media (25 mL) supplemented with different concentrations of manganese phosphite (MnPhi) diluted in water (0, 25, 37.5, 50, 100, 200, 300, 400, 500, 800 and 1000 μg/mL). Mycelial growth sensitivity was analyzed using logarithmic linear regression analysis. The MnPhi concentration needed to inhibit 50% of the mycelial growth (IC50) ranged from… More >

    Changes in Anatomical Features and Protein Pattern of Sunflower Partially Resistant and Susceptible Lines During Infection By Virulence Factors of Sclerotinia Sclerotiorum

    Maryam Monazzah1, Sattar Tahmasebi Enferadi1,*, Zohre Rabiei1 and Alessandro Mattiello2

    Phyton-International Journal of Experimental Botany, Vol.88, No.2, pp. 149-159, 2019, DOI:10.32604/phyton.2019.05053

    Abstract Helianthus annuus L. as an oil seed crop is widely grown throughout the world. One of the most destructive diseases of sunflower is stem rot caused by Sclerotinia sclerotiorum. Oxalic acid is the major virulence factor of this necrotrophic pathogen. It is important to further investigate plant responses to this non-specific toxin. Therefore, in the present study, we compared the patterns of total soluble proteins and xylem morphology of partially resistant and susceptible sunflower lines after treatment with Sclerotinia culture filtrate. The basal stems of both lines were treated with 40 mM oxalic acid (pH 3.7) of fungus culture filtrate… More >
