Min Jeong Kim, Chang Ki Shim, Jong-Ho Park 한국식물병리학회 The Plant Pathology Journal 16 Pages
한국식물병리학회 The Plant Pathology Journal 2021, 37권 6호 8 580-595 (16 pages)
Although late blight is an important disease in eco- friendly potato cultivation in Korea, it is highly depen- dent on the use of eco-friendly agricultural materials and the development of biological control technology is low. It is a necessary to develop an effective biocontrol agent to inactivate late blight in the field. AFB2-2 strain is a gram-positive with peritrichous flagella. It can uti- lize 20 types of carbon sources, like L-arabinose, and D- trehalose at 35°C. The optimal growth... -
Genetic Diversity and Population Structure of the Xanthomonas campestris pv. campestris Strains Affecting Cabbages in China Revealed by MLST and Rep-PCR Based Genotyping

Xanthomonas campestris pv. campestris (Xcc) is the causal agent of black rot for cruciferous vegetables worldwide, especially for the cole crops such as cabbage and cauliflower. Due to the lack of resistant cabbage cultivars, black rot has brought about considerable yield losses in recent years in China. Understanding of the pathogen features is a key step for disease prevention, however, the pathogen diversity, population structure, and virulence are largely unknown. In this study, we studied... -

Forty-eight spring barley genotypes were evaluated for deoxynivalenol (DON) concentration under natural infection across 5 years at Harrington, Prince Edward Island. These genotypes were also evaluated for Fusari- um head blight (FHB) severity and DON concentration under field nurseries with artificial inoculation of Fusarium graminearum by the grain spawn method across 2 years at Ottawa, Ontario, and one year at Hangzhou, China. Additionally, these genotypes were also evaluated for FHB severity... -
The Plant-Stress Metabolites, Hexanoic Aacid and Melatonin, Are Potential “Vaccines” for Plant Health Promotion
Anne J. Anderson, Young Cheol Kim 한국식물병리학회 The Plant Pathology Journal 13 Pages

A plethora of compounds stimulate protective mecha- nisms in plants against microbial pathogens and abiotic stresses. Some defense activators are synthetic com- pounds and trigger responses only in certain protective pathways, such as activation of defenses under regula- tion by the plant regulator, salicylic acid (SA). This review discusses the potential of naturally occurring plant metabolites as primers for defense responses in the plant. The production of the metabolites, hexanoic acid and... -
Isolate Virulence and Cultivar Response in the Winter Wheat: Pyrenophora tritici-repentis (Tan Spot) Pathosystem in Oklahoma
Kazi A. Kader, Robert M. Hunger, Mark E. Payton 한국식물병리학회 The Plant Pathology Journal 8 Pages

in cultivars detected increased variance in virulence of the isolates (r = 0.76, P < 0.01). A signifi- cant isolate × cultivar interaction indicated specificity between isolates and cultivars, however, cluster analysis indicated low to moderate physiological specialization. Similarity in wheat cultivars in response to pathogen isolates also was determined by cluster analysis. The use of diverse isolates of the fungus would facilitate evaluation of resistance in wheat cultivars to tan spot. -
Medicago truncatula in Interaction with Fusarium and Rhizoctonia Phytopathogenic Fungi: Fungal Aggressiveness, Plant Response Biodiversity and Character Heritability Indices
Marwa Batnini, Imen Haddoudi, Wael Taamali, Naceur Djebali, Mounawer Badri, Moncef Mrabet, Haythem Mhadhbi 한국식물병리학회 The Plant Pathology Journal 14 Pages

Fusarium and Rhizoctonia genera are important patho- gens of many field crops worldwide. They are constant- ly evolving and expanding their host range. Selecting resistant cultivars is an effective strategy to break their infection cycles. To this end, we screened a collection of Medicago truncatula accessions against Fusarium oxysporum, Fusarium solani, and Rhizoctonia solani strains isolated from different plant species. Despite the small collection, a biodiversity in the disease response of... -
Antagonistic and Plant Growth-Promoting Effects of Bacillus velezensis BS1 Isolated from Rhizosphere Soil in a Pepper Field

Pepper (Capsicum annuum L.) is an important agricul- tural crop worldwide. Recently, Colletotrichum scovillei, a member of the C. acutatum species complex, was re- ported to be the dominant pathogen causing pepper an- thracnose disease in South Korea. In the present study, we isolated bacterial strains from rhizosphere soil in a pepper field in Gangwon Province, Korea, and assessed their antifungal ability against C. scovillei strain KC05. Among these strains, a strain named BS1 significantly... -

Bacillus pumilus is the causal agent of trunk bulges dis- ease affecting rubber and rubberwood quality and yield production. In this study, B. pumilus and other closely related species were included in B. pumilus group, as they shared over 99.5% similarity from 16S rRNA analysis. Multilocus sequence analysis (MLSA) of five housekeeping genes and repetitive elements-based poly- merase chain reaction (rep-PCR) using REP, ERIC, and BOX primers conducted to analyze the diversity and systematic... -
Carbamoyl Phosphate Synthase Subunit CgCPS1 Is Necessary for Virulence and to Regulate Stress Tolerance in Colletotrichum gloeosporioides

Glomerella leaf spot (GLS) is a severe infectious dis- ease of apple whose infective area is growing gradually and thus poses a huge economic threat to the world. Different species of Colletotrichum including Colleto- trichum gloeosporioides are responsible for GLS. For efficient GLS control, it is important to understand the mechanism by which the cruciferous crops and C. gloeosporioides interact. Arginine is among one of the several types of amino acids, which plays crucial role in biochemical... -

The genus Streptomyces demonstrates enormous prom- ise in promoting plant growth and protecting plants against various pathogens. Single and consortium treat- ments of two selected Streptomyces strains (Streptomyces shenzhenensis TKSC3 and Streptomyces sp. SS8) were evaluated for their growth-promoting potential on rice, and biocontrol efficiency through induced systemic re- sistance (ISR) mediation against Xanthomonas oryzae pv. oryzicola (Xoc), the causal agent of rice bacterial leaf streak...
