Molecular characterization and detection of 16SrIII group phytoplasma associated with huanglongbing symptoms
(2019-03-01)
When huanglongbing (HLB) was found in Brazil in 2004, ‘Candidatus Liberibacter americanus’ was infecting most of the trees while ‘Ca. L. asiaticus’ was present in a minor proportion. Currently, ‘Ca. L. asiaticus’ is the ...
Cixiidae and Derbidae (Hemiptera) putative vectors of phytoplasma of group 16 SrIV.
(Universidad del ValleColombia, 2020-12-26)
The phytoplasmas of the 16SrIV group cause lethal yellowing diseases (STAL) in palms worldwide. The Phytoplasma of coconut lethal yellowing (LY) has been known as 'Candidatus Phytoplasma palmae' (16SrIV-A). Like LY, many ...
The crystal structure of the malic enzyme from candidatus phytoplasma reveals the minimal structural determinants for a malic enzyme
(Wiley Blackwell Publishing, Inc, 2018-04)
Phytoplasmas are wall-less phytopathogenic bacteria that produce devastating effects in a wide variety of plants. Reductive evolution has shaped their genome, with the loss of many genes, limiting their metabolic capacities. ...
