Other claims from this paper (19)
- Observation The sunn mutant retained normal ethylene sensitivity for nodulation.
- Observation The sunn mutant root growth was ethylene insensitive.
- Observation In sunn, infection and nodule development occurred mainly opposite xylem poles.
- Observation In sickle, infection and nodulation occurred around the developing root circumference.
- Observation sunn and sickle were separate unlinked loci.
- Observation The sunn/sickle double mutant had an additive super-nodulation phenotype.
- Observation Grafting showed the sunn phenotype depended on shoot genotype.
- Method / resource SNPs were useful for assessing wild Eurycoma genetic diversity.
- Observation Biotin depletion caused inactive MCCase A subunit accumulation.
- Observation Biotin depletion caused both MCCase subunits to hyperaccumulate.
- Observation Biotin-depleted seedlings failed to induce MCCase transcription under low carbon.
- Observation A second maize cisZOG gene was isolated.
- Observation cisZOG1 expression was high in maize roots and kernels.
- Observation cisZOG2 expression was high in roots but low in kernels.
- Observation cis-isomer O-glucosides were found in maize roots, young cobs and kernels.
- Observation cis-isomers were more prevalent in maize roots, stems and leaves.
- Observation trans-isomers were more abundant in maize kernels.
- Observation Yeast PDR5 was identified with specificity for tropane alkaloids.
- Intervention effect Introducing PDR5 increased tropane alkaloid secretion from tobacco cells.
