Other claims from this paper (12)

Method / resource The authors produced chromosome-level genome assemblies for M. indica and M. denticulata.
Observation M. indica is the higher nervonic acid producer.
Observation M. denticulata is the lower nervonic acid producer.
Observation Both species retained considerable repetitive sequences.
Observation The species had similar chromosome arrangements.
Observation The species had analogous regulation models during capsule maturation.
Association Faster nervonic acid accumulation in M. indica correlated with streamlined fatty acid and TAG pathway genes and regulators.
Observation M. denticulata showed diverse environmental response and more analogous or redundant duplications.
Observation Cold, ABA and phosphate starvation were major elicitors for M. indica.
Observation KCS, PDAT and DGAT were identified as core genes for M. indica.
Observation M. indica resequencing revealed geography-specific gene polymorphisms.
Observation M. indica resequencing revealed migration pathways.
