Extracellular enzymes of Colletotrichum fructicola isolates associated to Apple bitter rot and Glomerella leaf spot

Bitter Rot of Apples: Recent Changes in What We Know and Implications for Disease Management

Apple growers, private consultants, and extension specialists have all noted that bitter rot is increasingly common and is causing sporadic but economically significant losses throughout the northeastern and north central apple growing regions of North America. Forty years ago, bitter rot was considered a “southern disease” and apples with bitter rot were rarely observed in northern production ...

Genome Sequences of Three Apple chlorotic leaf spot virus Isolates from Hawthorns in China

The genome sequences of Apple chlorotic leaf spot virus (ACLSV) isolates from three accessions of hawthorns (Crataegus pinnatifida) grown at Shenyang Agricultural University were determined using Illumina RNA-seq. To confirm the assembly data from the de novo sequencing, two ACLSV genomic sequences (SY01 and SY02) were sequenced using the Sanger method. The SY01 and SY02 sequences obtained with...

An Investigation of Apple Chlorotic Leaf Spot (ACLSV) and Tomato Ring Spot (ToRSV) in Some Iranian Pear Gardens

Background and Aims: In spite of a long tradition of fruit-tree growing in all provinces of Iran, information on pear (Pyrus communis) tree viruses is scant. In order to identify of the nature of the virus like symptoms and decline in pear trees, we carried out a survey for the occurrence of four important viruses. Materials and Methods: Leaf samples of pear showing virus like symptoms wer...

Resistance of Strawberry Cultivars to Crown Rot Caused by Colletotrichum gloeosporioides Isolates from Florida Is Nonspecific

Colletotrichum crown rot of strawberry (Fragaria × ananassa Duchesne) can be caused by any of three fungi, Colletotrichum gloeosporioides (teleomorph Glomerella cingulata), C. fragariae, or C. acutatum (17,27). The closely related species C. fragariae and C. gloeosporioides produce a reddish-brown necrosis of crown tissue following infection that causes plants to wilt and collapse (27). Under g...
