Other claims from this paper (10)
- Observation The BARE family has more than 10(4) copies in the barley genome.
- Observation BARE1 elements are transcribed, translated, and form virus-like particles.
- Observation BARE2 elements cannot produce the GAG capsid protein.
- Observation The two BARE LTR promoters vary independently in activity among tissues.
- Observation TATA1 was almost inactive in embryos.
- Observation LTR deletions revealed strong positive and negative regulatory elements.
- Observation The promoters generated transcript groups differing in ends, sequences, and polyadenylation.
- Observation Some transcript groups lack common end structures needed for template switching.
- Observation Only about 15% of BARE transcripts are polyadenylated.
- Mechanism Distinct BARE transcript subfamilies may separately supply proteins and replication templates.
