Virus infection causes an increase in the quantity of ribosomes extracted<br />

from the hypocotyls of mungbeans. Though this increase is not confined to a<br />

particular size of ribosome, presumptive virus messenger RNA is associated<br />

predominantly with polyribosomes composed of nine or more monoribosomes. [AS]<br />

(REP.MB-2395)<br />

Infectivity studies have shown that the multiplication of tobacco necrosis<br />

virus can be inhibited by cycloheximide but not by chloramphenicol, and that it<br />

is likely that cycloheximide inhibits the synthesis of at least two.proteins<br />

necessary for multiplication. [AS]<br />

(REP.MB-1652)<br />

Changes in agronomic characteristics and protein contents of mungbean<br />

(Vigna radiata Wilczek) cv. Sheela as influenced by arhar mosaic isolates (ASM<br />

and AMM) infection was studied. Isolate ASM caused more reduction in growth and<br />

yield in comparison to the AMM isolate. Infected plant samples have lower dry<br />

weight but higher moisture contents in comparison to their healthy<br />

counterparts. The protein content was higher in healthy mungbean than virus<br />

isolate-infected mungbean. The protein content was the highest in seeds,<br />

followed by leaves, stems and roots. Virus infection reduced the protein<br />

percentage in seeds, leaves and stemF. but was the same in healthy and AMM<br />

isolate-infected mungbean roots. [ASJ<br />

(REP.MB-1404)<br />

Cowpea (Vigna sinensis) C-20 was found to be a local lesion host for<br />

mungbean leaf curl virus. Two types of spots, i.e., chlorotic and necrotic,<br />

developed as a result of viral infection. [EMSJ<br />

JOURNAL OF GENERAL VIROLOGY, v.28:373-379. [En] [En AbstJ (REP.MB-0878)<br />

Jack bean (Canavalia ensiformis) and French bean (Phaseolus vulgaris) cv.<br />

The Prince were useful diagnostic hosts for broad bean stain virus (BBSV) and<br />

Echtes Ackerbohnenmosaik-Virus (EAMV). Bottom and middle component of each<br />

virus complemented one another to give greatly increased infectivity but there<br />

was no complementation between components from the different viruses. Bottom<br />

and middle components of each virus were indistinguishable serologically. Both<br />

BBSV and EAMV can infect mungbean. IAS/THHJ<br />
