Determination of Chromosome Numbers and Genome Sizes in Six Species of Byblis (Byblidaceae)

Takahiro Katogi; Yoshikazu Hoshi CYTOLOGIA 2022. doi:10.1508/cytologia.87.277

Other claims from this paper (7)

Observation The B. liniflora complex included diploid and tetraploid chromosome counts of 2n=16 and 32.
Observation B. gigantea had only tetraploid chromosome counts of 2n=36.
Observation B. gigantea had the highest measured 2C DNA content, 1.93 pg.
Observation Diploid B. filifolia had 2C content of 0.70 pg.
Observation Tetraploid B. filifolia had 2C content of 1.81 pg.
Observation The haploid genome of tetraploid B. filifolia was 1.3 times larger than that of the diploid.

Title

Seed-dormancy depth is partitioned more strongly among habitats than among species in tropical ephemerals

Adam T. Cross; Matthew D. Barrett; Shane R. Turner; et al. Australian Journal of Botany 2018. doi:10.1071/bt17244

Other claims from this paper (14)

Intervention effect Karrikinolide significantly increased germination in all six Byblis species.
Intervention effect Ethylene significantly increased germination in all six Byblis species.
Intervention effect Warm dry after-ripening amplified the stimulant response in B. filifolia.
Association Seed dormancy depth was partitioned more strongly among habitats than among species.
Association Germination response to KAR1 was partitioned more strongly among habitats than species.
Association Germination response to ethylene was partitioned more strongly among habitats than species.
Association Shallow sandy soil populations produced less dormant seeds than deeper sand or cracking clay populations.
Observation Shallow soil habitats had higher average upper-soil temperatures.
Observation Shallow soil habitats had greater diurnal temperature fluctuations.
Observation Shallow soil habitats had reduced moisture persistence.
Mechanism Habitat thermal and hydrological differences appear to drive Byblis seed dormancy depth.
Observation Widely distributed Byblis species show high plasticity in dormancy depth and germination responses among habitats.
Observation Sympatric species showed similar responses.
Recommendation The authors recommend further study of plasticity and local adaptation of seed traits.
