Other claims from this paper (18)
- Observation Chinese Spring carries the functional TaNAM-B1, whose nucleotide sequence was identical to the wild-type TtNAM-B1 of T. turgidum var. dicoccoides.
- Observation Gpc-1 and Gpc-2 were widely expressed in the studied tissues, except root where only Gpc-1 transcript was detected.
- Observation By in situ hybridization, no transcripts were found in leaf epidermal cells, pericarp or seed coat.
- Observation Transcripts mainly aggregated in leaf mesophyll cells, aleurone layer, embryo and the mineral-transport tissues of the grain.
- Observation The highest expression level was observed in the embryo.
- Observation Lower expression was detected in the peduncle and leaf vascular bundle.
- Observation Ta NAM-D2 was expressed less than the other genes in all tested tissues.
- Observation Ta NAM-D1 was the most abundant gene in wheat kernel.
- Observation Ta NAM-B2 was the most abundant gene in peduncle, glume and rachis.
- Observation Expression of Ta NAM-B2 and Ta NAM-A1 was the highest in flag leaf among the five NAM genes.
- Observation Ta NAM-A1, Ta NAM-B1, Ta NAM-B2 and Ta NAM-D2 were expressed in all studied tissues before anthesis.
- Observation Ta NAM-D1 was expressed only from the first-flowering date.
- Observation Ta NAM-A1 transcript abundance began to decline at 15 DAA in penultimate leaf, rachis and kernel, earlier than in flag leaf (25 DAA) and other tissues.
- Observation Transcription of Ta NAM-B1 and Ta NAM-D2 kept increasing until the late filling stage in most organs.
- Observation Ta NAM-B2 expression decreased from 15 DAA in most tested tissues.
- Observation Ta NAM-D1 transcript abundance grew consistently until 25 and 30 DAA.
- Association No obvious relationship was observed between the five NAM genes and PCD in wheat grain.
- Mechanism The authors propose Gpc-1 and Gpc-2 may directly regulate nutrient remobilization only, or in parallel with senescence, during grain filling.
