Viruses infecting wild flora may have a significant negative impact on nearby crops, and vice-versa. Only limited information is available on wild species able to host economically important viruses that infect sweetpotatoes (Ipomoea batatas). In this study, Sweet potato chlorotic fleck virus (SPCFV; Carlavirus, Betaflexiviridae) and Sweet potato chlorotic stunt virus (SPCSV; Crinivirus, Closte...

In tissue culture, high production cost of the products restricts their reach. Though tissue culture is a major strength in floriculture it is marred by pricing issues. Hence, we developed a complete regeneration low cost micropropagation protocol for an economically important floriculture crop, carnation (Dianthus caryophyllus L.). Successful regeneration of carnation from nodal explants on co...

Soybean chlorotic mottle virus (SbCMV) is the type species of the genus 'Soybean chlorotic mottle-like viruses', within the family Caulimoviridae. The double-stranded DNA genome of SbCMV (8178 bp) contains eight major open reading frames (ORFs). Viral genes essential and non-essential for the replication and movement of SbCMV were investigated by mutational analysis of an infectious 1.3-mer DNA...

Efforts to control viral diseases in crop production include several types of physical or chemical treatments; antiviral extracts of a number of plants have also been examined to inhibit plant viral infection. However, treatments utilizing naturally selected microorganisms with activity against plant viruses are poorly documented. Here we report isolation of a soil inhabiting bacterium, Pseudom...

Virus infection in chili plants may cause various symptoms. The complexity of the symptoms and human vision ability often become limiting factors during disease investigations. Digital image analysis is expected to a method assist comprehensively describing plant viruses. A survey was conducted on cayenne pepper fields Southeast Sulawesi Province observe virus virtually record symptomatic using...

Plant pathogens are a serious problem for seed export, plant disease control and plant quarantine. Rapid and accurate screening tests are urgently required to protect and prevent plant diseases spreading worldwide. A novel multiplex detection method was developed based on microsphere immunoassays to simultaneously detect four important plant pathogens: a fruit blotch bacterium Acidovorax avenae...

-Twenty four isolates of peanut stripe virus from 8 d1fferent countnes were compared under controlled cond1tions at the Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD). Montpelher, France. The isolates had thetr origins from Burma, lndia, Jndones1a, Phîhppincs, China. Tha1\and and USA. Four of the isolates were collected from Thaîland in 1972 but mamt...
