Ca. Liberibacter asiaticus
Abstract
Huanglongbing (HLB) is a citrus infectious disease caused by ‘Candidatus Liberibacter’ spp. Recently, it has begun to spread rapidly worldwide, causing significant losses to the citrus industry. Early diagnosis of HLB relies on quantitative real-time PCR assays. However, the PCR inhibitors found in the nucleic acid extracted from plant materials pose challenges for PCR assays because they may result in false-negative results. Internal standard (IS) can be introduced to establish a single-tube d

First Report of ‘Candidatus Phytoplasma asteris’-related Strain (16SrI group) Associated with Small Leaves, Leaf Yellowing, and Shoot Proliferation of Morning Glory (Ipomoea biflora) in Taiwan

Abstract
Ipomoea biflora L., commonly known as morning glory, is an herbaceous vine plant in the Convolvulaceae family and is widespread at low elevations in Taiwan and other East Asian countries. In September 2023, six I. biflora plants exhibiting small leaves, leaf yellowing, and shoot proliferation were observed in a vacant lot in Taiwan Agricultural Research Institute (TARI), Wufeng District, Taichung, Taiwan, representing 100% disease incidence in the area. All the symptomatic morning glory climbed

Mixed infections of Tomato yellow leaf curl New Delhi virus and a ‘Candidatus Phytoplasma asteris’ strain in zucchini squash in Italy

Names
Ca. Phytoplasma asteris
Abstract
A new disease syndrome of zucchini squash was observed in Southern Italy, in 2018 and again in 2020. Affected plants were severely stunted and leaves were bent downwards, small, stiff, thick, leathery, and had interveinal chloroses. In addition, flowers were virescent and fruits were deformed and often cracked. Disease incidence was 20 and 30% in two different zucchini cultivations in Campania region (Southern Italy). Tomato yellow leaf curl New Delhi virus (ToLCNDV) was detected in eight sample

Terrirubrum flagellatum gen. nov., sp. nov. of Terrirubraceae fam. nov. and Lichenibacterium dinghuense sp. nov. from forest soil and proposal of Rhodoblastaceae fam. nov

Names
Terrirubraceae
Abstract
Two Gram-negative, aerobic, rod-shaped bacterial strains, 7MK25T and 6Y81T, were isolated from forest soil of Dinghushan Biosphere Reserve, Guangdong Province, PR China. Based on the results of 16S rRNA gene sequence analysis, strain 7MK25T showed the highest similarity (93.6 %) to Methyloferula stellata AR4T, followed by Bosea thiooxidans DSM 9653T (93.3 %). Strain 6Y81T had the highest similarity of 97.9 % to Lichenibacterium minor RmlP026T, followed by Lichenibacterium ramalinae RmlP001T (97.

The Effect of Biotic Stress in Plant Species Induced by ‘Candidatus Phytoplasma solani’—An Artificial Neural Network Approach

Citation

Names
Ca. Phytoplasma solani
Abstract
Infections with phytoplasma present one of the most significant biotic stresses influencing plant health, growth, and production. The phytoplasma ‘Candidatus Phytoplasma solani’ infects a variety of plant species. This pathogen impacts the physiological and morphological characteristics of plants causing stunting, yellowing, leaf curling, and other symptoms that can lead to significant economic losses. The aim of this study was to determine biochemical changes in peony (Paeonia tenuifolia L.), m

Spatial chemistry of citrus reveals molecules bactericidal to Candidatus Liberibacter asiaticus

Ca. Liberibacter asiaticus
Abstract
Abstract Huanglongbing (HLB), associated with the psyllid-vectored phloem-limited bacterium, Candidatus Liberibacter asiaticus (CLas), is a disease threat to all citrus production worldwide. Currently, there are no sustainable curative or prophylactic treatments available. In this study, we utilized mass spectrometry (MS)-based metabolomics in combination with 3D molecular mapping to visualize complex chemistries within plant tissues to explore how these chemistries change in vivo in HLB

Arcicella gelida sp. nov. and Arcicella lustrica sp. nov., isolated from streams in China and re-examining the taxonomic status of all the genera within the families Spirosomataceae and Cytophagaceae

Chryseotaleaceae Leadbetterellaceae Flectobacillaceae
Abstract
Three Gram-stain-negative, aerobic, rod-shaped, non-motile strains (DC2WT, DC25WT, and LKC2W) were isolated from streams in China. Comparisons based on the 16S rRNA gene sequences showed that these three strains share 16S rRNA gene sequence similarity values over 97.0 % with the species of genus Arcicella. There was confusion due to the fact that all species of genera Flectobacillus, Aquirufa, and Sandaracinomonas show 16S rRNA gene sequence similarity of over 90.0 % to the above three strains,

Abstract
AbstractBACKGROUNDCitrus huanglongbing (HLB) is a devastating disease caused by Candidatus Liberibacter asiaticus (CLas) that affects the citrus industry. In nature, CLas relies primarily on Diaphorina citri Kuwayama as its vector for dissemination. After D. citri ingests CLas‐infected citrus, the pathogen infiltrates the insect's body, where it thrives, reproduces, and exerts regulatory control over the growth and metabolism of D. citri. Previous studies have shown that CLas alters the composit
