A method of multiplex polymerase chain reaction (PCR) was developed for the simultaneous detection of Citrus yellow mosaic virus (CYMV) and fastidious Citrus greening bacterium, Candidatus Liberibacter asiaticus (CLa) in sweet orange trees. Initially total DNA from individual CLa and CYMV infected citrus plants were mixed and both pathogens were detected simultaneously by multiplex PCR. Subsequ...

The leaves of Stevia rebaudiana, from Asteraceae family, are a source steviol glycosides, which utilized as sweeter, more favorite addition. Among the most important anatomical results that were reached through research and distinguish plant an point view uniseriate-multicellular non-glandular trichomes covered epidermis stem leaves. Also, vertical walls ordinary cells in upper lower heavily si...

Abstrak: Media tanam pada pembibitan kelapa sawit umumnya terdiri atas tanah yang dicampur dengan pasir serta pupuk anorganik seperti fosfat. Bahan organik sering dimanfaatkan untuk lebih meningkatkan produktifitas media tanam. Tujuan penelitian mengetahui pengaruh biochar pelepah dan pemberian dosis fosfat pre nursery sawit. Penelitian dilaksanakan di Biochar Research Station Laboratorium Ilmu...

Nymphaea has seven species already catalogued in the flood prone areas of the Brazilian Pantanal. However, some species remain difficult to identify and descriptions of the anatomy of vegetative organs are an important tool for infrageneric separation to aid in group taxonomy. The species collected in the Pantanal and prepared according to the usual techniques for anatomical studies showed simi...

A phloem-limited bacterium, 'Candidatus Liberibacter asiaticus' (Las) is a major pathogen of citrus greening (huanglongbing), one of the most destructive citrus diseases worldwide. The rapid identification and culling of infected trees and budwoods in quarantine are the most important control measures. DNA amplification including conventional polymerase chain reaction (PCR) has commonly been us...
