Table 1.

HdIV segments predicted to encode the rep genes analysed in this work. Segment names and putative sizes are indicated. Segment names were given alphabetically from the shortest to the longest; however only segments for which a real (completely sequenced; SH-E and SH-G) or estimated (PCR fragment; SH-J, SH-H and SH-A2 containing rep7 sequence) size could be given were named. SH-x and SH-y stand for segments of unknown size (since molecular weigh marker represents linear DNA).Rep7 is underlined because of discrepancy between PCR and Southern-blot results. For each segment, the rep gene(s) identified after sequencing of PCR amplification fragments or by Southern-blot analysis are reported

segment	size (kbp)	sequencing/PCR	Southern-blot
SH-J	~6	rep5, rep11	rep4
SH-y	~5	--------	rep7?
SH-H	~5	rep6
SH-G	5.6	rep12
SH-E	4.6	rep1, rep2, rep3
SH-x	?	--------	rep8
SH-A2	3.1	rep7
