First Report of Nigrospora sphaerica Causing Shot Hole Disease on Mulberry in China

First report on a novel Nigrospora sphaerica isolated from Catharanthus roseus plant with anticarcinogenic properties

This paper reports on the vinca alkaloid produced by a novel Nigrospora sphaerica isolated from Catharanthus roseus. Through liquid chromatography-mass spectrometry (LCMS), only the crude mycelia extract of this fungus was positive for determination of vinblastine. This vinca alkaloid was then purified by using high-performance liquid chromatography (HPLC) and tested for cytotoxicity activity u...

evaluation of relative resistance of some apricot varieties to wilsonomyces carpophilus causing shot hole disease

in this study, eleven cultivars of apricot including two early ripening (noori pishras and pishras tabasi) varieties, four mid ripening cultivars namely (shahroudi, lasjrdy, ghazi gahani and bagheri) and five late ripening cultivars i.e. (shahroudi51, shahroudi48, shahroudi29, shahroudi21 and ketabi) that had a better yield and horticultural characteristics were screened to wilsonomyces carpoph...

A new report of a mosaic dwarf viroid-like disease on mulberry trees in China.

A viroid-like disease causing mosaic leaves and dwarfism was found on mulberry plants in Zhejiang, China. Grafting of stems from infected plants onto healthy plants resulted in the same symptoms on the healthy plants. A circular small RNA (Mmd-v RNA1) was isolated from the infected plant leaves and caused identical symptoms after more than two years. Nucleotide sequencing indicated that the Mmd...
