Other claims from this paper (12)
- Intervention effect High N increased relative epidermal cell elongation rates by 9%.
- Intervention effect High N increased leaf elongation rate by 89%.
- Observation Cell elongation lasted about 20 hours longer in the high-LER genotype, regardless of N.
- Observation The proportion of dividing mesophyll cells was greater in the high-LER genotype.
- Intervention effect High N increased the percentage of dividing mesophyll cells in both genotypes.
- Observation Mesophyll cell division continued after epidermal division stopped, until epidermal cells reached 40 micrometers in high-LER plants.
- Observation The corresponding epidermal cell length was 50 micrometers in the low-LER genotype.
- Observation Mesophyll cell cycle length was calculated as 12 to 13 hours.
- Intervention effect Nitrogen increased mesophyll cell number more than epidermal cell number.
- Observation Final adjacent mesophyll cell number was 10 under low N.
- Observation Final adjacent mesophyll cell number was 14 under high N.
- Method / resource A spatial model illustrates overlap of mesophyll division and epidermal elongation and the transition to secondary wall deposition.
