to the phloem with reduced genomic template. Since they are limited to phloem, it spreads systemically within the plant system and are transmitted from plant to another by sap-feeding vector insects and grafting (Bendix and Lewis 2018; Guldur et al., 2019; Sugio et al., 2011). It causes serious economic losses in many plants around the world and posses serious threats especially to fruit... Changes in physiological and biochemical patterns in lucerne plants caused by the presence of ‘Candidatus Phytoplasma australasia’, which is one of the significant pathogens causing yield losses in lucerne plants, were investigated. Significant differences were evident in total chlorophyll, chlorophyll a, chlorophyll b, and protein amounts between ‘Ca. Phytoplasma australasia’- positive and negative lucerne plants. Stress-related metabolites such as phenol, malondialdehyde, and proline... -

This dis- ease also occur from the root and continues up to the base of the stem. The infection from these roots is caused by the spread of pathogenic inoculum through rainwater flow or splashes. In some locations in a district affected... a new ITS group, the ITS7b haplotype that was localized in Musi Banyuasin. Both haplotypes were highly pathogenic to duku. Inoculation tests on various forest and agroforestry plant hosts showed that both haplotypes were highly pathogenic to Acacia mangium, moderately pathogenic to Acacia carsicarpa, Eucalyptus urophylla, and Melaleuca cajuputi, but weakly pathogenic to Dyera costulata, Hevea brasiliensis, and Alstonia scholaris. Therefore, this pathogen becomes a serious threat to Indonesia’s... -

V., Garcia, O., Brown, R., Hugenholtz, P., DeSantis, T. Z., Andersen, G. L., Wiener-Kronish, J. P. and Bristow, J. 2007. Loss of bacterial diversity during antibiotic treatment of intubated patients colonized with... Brown leaf spot disease caused by Nigrospora guilin- ensis on Phellodendron chinense occurs in a large area in Dayi County, Chengdu City, Sichuan Province, China each year. This outbreak has severely reduced the production of Chinese medicinal plants P. chinense and caused substantial economic losses. The bacterial isolate JKB05 was isolated from the healthy leaves of P. chinense, exhibited antagonistic effects against N. guilinensis and was identified as Bacillus megaterium. The following... -

beetle entry/exit holes on peeled-off bark from squirrel scratches, suggesting the involvement of the wild vertebrate as the wound creator and beetles for fungal spore dispersion. Fungal feeding insects, such as H. mangiferae, have been suggested to be associated with the rapid distri- bution of C. fimbriata in Oman and Pakistan (Al Adawi et al., 2013). Squirrel attacks on either diseased or... Bark canker, wood discoloration, and wilting of the duku tree (Lansium domesticum) along the watershed of Komering River, South Sumatra Province, Indonesia first appeared in 2013. The incidence of tree mortality was 100% within 3 years in badly infected orchards. A Ceratocystis species was consistently isolated from the diseased tissue and identified by morphological and sequence analyses of the internal transcribed spacer (ITS) and β-tubulin regions. Pathogenicity tests were conducted and... -

fungi comprise the largest group of fungi that live in either bulk or rhizo- sphere soil, and can survive on non-living matters such as fallen trees, cow feces, dead leaves, and even dead insects and animals. They acquire their nutrition by digesting these complicated dead matters into elementary substances using extracellular enzymes, and thus have a crucial ecologi- cal role in soil... Volatile compounds (VOCs) are not only media for communication within a species but also effective tools for sender to manipulate behavior and physiology of receiver species. Although the influence of VOCs on the interactions among organisms is evident, types of VOCs and specific mechanisms through which VOCs work during such interactions are only beginning to become clear. Here, we review the fungal volatile compounds (FVOCs) and their impacts on different recipient or- ganisms from perspective... -

viruses, bacteria, fungi, insects, higher plants, and animals. These enzymes are involved in various biological processes, including morphogenesis, nutrition, and defense against pathogens contained in their cell walls (Yan and Fong, 2015). Chi- tinolytic enzymes have been commercially used to pro- duce chitooligosaccharides and NAG as part of pharma- ceutical formulations. Purifed chitinase... Chitinase-producing Paenibacillus elgii strain HOA73 has been used to control plant diseases. However, the antimicrobial activity of its extracellular chitinase has not been fully elucidated. The major extracellular chitinase gene (PeChi68) from strain HOA73 was cloned and expressed in Escherichia coli in this study. This gene had an open reading frame of 2,028 bp, encoding a protein of 675 amino acid residues containing a secretion signal peptide, a chitin-binding domain, two fibronectin type... -

variety of pathogens, including bacteria, fungi, viruses, nematodes, insects, and mammals. Plant diseases caused by pathogen attack result in major economic losses in many important crop plants worldwide. To protect themselves against pathogen infec- tion, plants have developed a sophisticated multi-tiered immune system, parts of which are similar to the human immune system and help fght off... SlMAPKKKα, a tomato (Solanum lycopersicum) mitogen-activated protein kinase kinase kinase, is a positive regulator of Pto-mediated effector-triggered immunity, which elicits programmed cell death (PCD) in plants. In this study, we examined whether putative phosphorylation sites in the conserved activation segment of the SlMAPKKKα kinase domain are critical for eliciting PCD. Three amino acids, threonine353, serine360 (Ser360), or serine364 (Ser364), in the conserved activation... -

develop their built-in immune responses against the attack of natural enemies who can colonize in host organisms (Buchmann, 2014; Jones and Dangl, 2006). Infection either pathogenic microbes or insects causes severe yield losses in crop plants (Agrios, 2005). Since plants lack specialized immune cells and cir- culatory systems, they have developed a unique immune system to protect themselves... ALD1 (ABERRANT GROWTH AND DEATH2 [AGD2]-LIKE DEFENSE1) is one of the key defense regulators in Arabidopsis thaliana and Nicotiana benthamiana. In these model plants, ALD1 is responsible for triggering basal defense response and systemic resistance against bacterial infection. As well ALD1 is involved in the production of pipecolic acid and an unidentified compound(s) for systemic resistance and priming syndrome, respectively. These previous studies proposed that ALD1 is a potential candidate for... -

the microorganisms (Garg and Chandel, 2010; Raven, 2010). Many microorganisms cause diseases in plants (Agrios, 2006). Some plant pathogens, especially viruses, also have strong interactions with insects and the insect transmission of viruses has been well documented. Sucking insects, such as leafhoppers and aphids, transmit plant pathogens. The reproduction and survival of host plants may ... Microorganisms have many roles in nature. They may act as decomposers that obtain nutrients from dead materials, while some are pathogens that cause diseases in animals, insects, and plants. Some are symbionts that enhance plant growth, such as arbuscular mycorrhizae and nitrogen fixation bacteria. However, roles of plant pathogens and diseases in natural ecosystems are still poorly understood. Thus, the current study addressed this deficiency by investigating possible roles of plant diseases in...
