Abstract
Specific scopeThis Standard describes a diagnostic protocol for ‘Candidatus Phytoplasma mali’, ‘Ca. P. pyri’ and ‘Ca. P. prunorum’.This Standard should be used in conjunction with PM 7/76 Use of EPPO diagnostic protocolsSpecific approval and amendmentApproved as PM 7/62 Candidatus Phytoplasma mali and PM 7/63 Ca. P. pyri in 2006. First revision in 2017‐02 as a single Standard as PM 7/62 (2) with the addition of ‘Ca. P. prunorum’. Second revision in 2019‐06.

Draft Genome Sequence of ‘Candidatus Phytoplasma pini’-Related Strain MDPP: A Resource for Comparative Genomics of Gymnosperm-Infecting Phytoplasmas

Citation
Cai et al. (2020). Plant Disease 104 (4)
Names
Ca. Phytoplasma pini
Abstract
‘Candidatus Phytoplasma pini’-related strain MDPP, the reference strain of subgroup 16SrXXI-B, is a pathogen associated with witches’ broom disease of Pinus spp. in North America. Here, we report the first draft genome sequence of ‘Ca. Phytoplasma pini’ strain MDPP, which consists of 474,136 bases, with a G + C content of 22.22%. This information will facilitate comparative genomics of gymnosperm-infecting phytoplasmas.

Genome Sequence Resource of ‘Candidatus Liberibacter asiaticus’ from Thailand

Citation
Li et al. (2020). Plant Disease 104 (3)
Names
Ca. Liberibacter asiaticus
Abstract
‘Candidatus Liberibacter asiaticus’ (Las) is an unculturable α-proteobacterium associated with citrus huanglongbing (HLB), a devastating disease currently threatening the citrus industry worldwide. Here, we present the genome sequence of Las strain TaiYZ2 from an HLB-affected pomelo tree in Hat Yai district, Songkhla Province, Thailand. The TaiYZ2 genome is composed of 1,230,623 bp with G+C content of 36.4%. This is the first Las genome sequence from Thailand, which will enrich current Las geno

Growth and Yield Performance of Solanum tuberosum Grown from Seed Potatoes Infected with ‘Candidatus Liberibacter solanacearum’ Haplotypes A and B

Citation

Names
“Liberibacter solanacearum”
Abstract
Zebra chip (ZC) disease of potato (Solanum tuberosum) is associated with infection by ‘Candidatus Liberibacter solanacearum’ (Lso). Two haplotypes of Lso—A and B—occur in the United States. Lso haplotype B is more virulent than haplotype A, causing greater disease incidence in tubers, more severe symptoms, and greater loss in tuber yield. This study assessed whether tubers from infected plants generate new infected plants the following year. The effects of both Lso haplotypes A and B on tuber r

Genome Resource for the Huanglongbing Causal Agent ‘Candidatus Liberibacter asiaticus’ Strain AHCA17 from Citrus Root Tissue in California, USA

Citation
Cai et al. (2020). Plant Disease 104 (3)
Names
Ca. Liberibacter asiaticus
Abstract
‘Candidatus Liberibacter asiaticus’ is the unculturable causative agent of citrus huanglongbing disease. Here, we report the first citrus root metagenome sequence containing the draft genome of ‘Ca. L. asiaticus’ strain AHCA17, obtained from a pummelo tree in California. The assembled genome was 1.2 Mbp and resulted in 37 contigs (N50 = 158.7 kbp) containing 1,057 predicted open reading frames and 45 RNA-coding genes. This draft genome will provide a valuable resource in further study of ‘Ca. L

Lso-HPE1, an Effector of ‘Candidatus Liberibacter solanacearum’, Can Repress Plant Immune Response

Citation
Levy et al. (2020). Phytopathology® 110 (3)
Names
“Liberibacter solanacearum”
Abstract
‘Candidatus Liberibacter solanacearum’ is a plant pathogen affecting the families Solanaceae and Apiaceae in different parts of the world. ‘Ca. L. solanacearum’ is a Gram-negative, fastidious α-proteobacterium that is vectored by different psyllid species. Plant-pathogenic bacteria are known for interfering with the host physiology or defense mechanisms, often by secreting bacterial effectors. Effector proteins are critical for virulence; therefore, the identification of effectors could help wi
