VIRUSES, VIROIDS AND BACTERIPHAGES

VIRUSES:

• TERM VIRUS( INFECTIVE FLUID) WAS COINED BY PASTEURE

• D J IWANOWSKY DISCOVERED VIRUS ( TMV)

• MW BEIJERINK CALLED VIRUSES TO BE INFECTIVE - EXTRACT FRO INFECTED TOBACCO COULD CAUSE INFECTION TO HEALTHY PLANTS. ( CONTAGIUM VIVUM FLUIDUM)

• W.M STANLEY : CRYSTALLISED VIRUSES

VIRUSES ARE THE CONNECTING LINK BETWEEN LIVING AND NONLIVING

STRUCTURAL COMPONENT;

• ENVELOPE ( HIV, HERPES)

• CAPSID

• NUCLEOID ( DNA OR RNA)

DNA CONTAING VIRUSES:

• DS DNA- POX VIRUS, HERPES VIRUS , CMV

• SS DNA VIRUSES- COLIPHAGE $\phi$  X174, M-13 PHAGE

RNA CONTAING VIRUSES

• DS RNA- REOVIRUSES, WOUND TUMOUR VIRUSES

• SS RNA VIRUSES -HIV, TMV, RETROVIRUSES

BACTERIOPHAGE

• DOUBLE STRANDED DNA

• TADPOLE LIKE STRUCTURE- POLYHEDRAL HEAD AND A HELICAL TAIL

• HEAD- NUCLEIC ACID + PROTEIN COAT

• TAIL - PROTEINACEOUS

TMV

• 2130 CAPSOMERES ARRANGED HELICALLY

• SS RNA( 6400 NUCLEOTIDES) AS GENETIC MATERIAL

• RATIO OF NUCLEOTIDES TO CAPSOMERES 3;1

VIROIDS, VIRUSOIDS AND PRIONS

• VIROIDS: DISCOVERED BY AO DIENER, INFECTIVE RNA PARTICLES DEVOID OF CAPSID ( PROTEIN COAT),CAUSE DISEASE LIKE PSTD( POTATO SPINDLE TUBER DISEASE)

• VIRUSOIDS: INFECTIVE RNA PARTICLES PRESENT INSIDE THE CAPSID OF OTHER LARGE VIRUSES

• PRIONS: INFECTIOUS PROTEIN PARTICLES
