Other claims from this paper (19)
- Observation 43 novel HHR-containing RNAs were identified in 16 plant species.
- Observation Most of the 43 RNAs (37) were predicted to be circular.
- Observation A viroid-like RNA was identified in Ulva lactuca, a green alga, as the first report in a lower plant.
- Observation RHVd-1, RHVd-2 and LHVd are three new viroids.
- Observation PgHVd-LR1 and CHVd-LR2 are two new viroid-like RNAs.
- Observation The field incidence of RHVd-1 in rose was 15.6% (10/64).
- Observation The field incidence of RHVd-2 in rose was 4.8% (12/252).
- Observation The field incidence of LHVd in lychee was 26.6% (17/64).
- Observation The field incidence of PgHVd-LR1 in guava was 5.7% (7/122).
- Observation The field incidence of CHVd-LR2 in citrus was 1.2% (1/82).
- Observation RHVd-1 infected China rose at an infection rate of 10% (3/29) after inoculation.
- Observation RHVd-2 infected China rose at an infection rate of 41% (9/22) after inoculation.
- Observation LHVd infected lychee plants at an infection rate of 32% (7/22) after inoculation.
- Observation RHVd-1 has the largest genome among known viroids, at 506 nt.
- Observation RHVd-1 extends the upper viroid size limit by 16.6%.
- Observation More than 30 viroid-like RNAs were found in plants, including a green alga.
- Method / resource sRNA profiles can, to some extent, distinguish bona fide viroids from viroid-like circular RNAs.
- Association PgHVd-LR1 and CHVd-LR2 are probably associated with microorganisms in guava and citrus.
- Observation Viroid-like circular RNAs identified from grapevine and Areca catechu were not detected in field-collected samples.
