The soil fungus Rhizoctonia solani is a pathogen of agricultural crops. Here, we report on the 51,705,945 bp draft consensus genome sequence of R. solani strain Rhs1AP. A comprehensive understanding of the heterokaryotic genome complexity and organization of R. solani may provide insight into the plant disease ecology and adaptive behavior of the fungus.

The symptomatology of Indian peanut clump virus (IPCV) isolates serologically, but could be d~stinguished from H-IPCV and L-IPCV collected from fise different geograph~cal locations. Bapatla (B). isolates in serological tests The l i k e isolates could not be d~st~ngu~shed on Chinnaganjam(C). Hjderabad (H). Ludhiana (L),and Talod (T).d~ffered. the basis of particle size. Each isolateconta~ned two R S A spec~es of 1.90X B-IPCV and C-IPCV were indistinguishable by host range but could be 10' and 1.65 x 10' M, estimated under nondenaturing cond~tions and a distinguished from the other isolates by symptoms on Canavalia single polypeptide of 24 X 10' M,.

Peanut clump. a soilborne virus disease, was first reported on peanut (Arochis hypogaea L.) in West Africa (16). The causal virus was shown to be rod-shaped (13) with two predominant particle lengths. 190and 245 nm, containing two R N A species of 1.7 X lob and 2.1 x lo6 M , (IS). Reddy et a l (9) have reported a similar

Horsegram yellow mosaic disease was shown to be caused by a geminivirus; horsegram yellow mosaic virus (HYMV). The virus could not be transmitted by mechanical sap inoculation. Leaf dip and purified virus preparations showed geminate virus particles, measuring 15‐18 * 30 nm. An antiserum for HYMV was produced and in enzyme‐linked immunosorbent assay (ELISA) and immunosorbent electron microscopy (ISEM) tests HYMV was detected in leaf extracts of fieldinfected bambara groundnut, french bean, groundnut, limabean, mungbean, pigeonpea and soybean showing yellow mosaic symptoms. Bemisia tabaci fed on purified HYMV through a parafilm membrane transmitted the virus to all the hosts listed above but not to Ageratum conyzoides, okra, cassava, cowpea, Croton bonplandianus, Lab‐lab purpureus, Malvastrum coromandalianum and tomato. No reaction was obtained in ELISA and ISEM tests between HYMV antibodies and extracts of plants diseased by whitefly‐transmitted agents in India such as A. conyzoides yellow mosaic, okra yellow vein mosaic, C. bonplandianus, yellow vein mosaic, M. coromandalianum yellow vein mosaic, tomato leaf curl and cassava mosaic. HYMV was also not found to be related serologically to bean golden mosaic, virus.
