Other claims from this paper (16)
- Observation Immunoblot analyses indicated at least two aquaporin isoforms in Norway spruce seeds during development.
- Observation One aquaporin isoform was abundant in mature Norway spruce seeds.
- Observation Another aquaporin isoform was detected in extracts of young Norway spruce seedlings, particularly in the roots.
- Observation Full-length gene mipfg was identified from Norway spruce seeds.
- Observation Full-length gene mipr was identified from Norway spruce roots.
- Observation The two identified genes showed high homology to the tonoplast sub-class of aquaporins.
- Observation In mature seeds, aquaporin labelling was high in the tonoplast of protein storage vesicles.
- Observation Before protein storage vesicle formation, labelling was seen in the plasmamembrane of jacket cells lining the archegonia in young female gametophytes.
- Observation In situ hybridization gave strong expression signals in jacket cells and in maturing seeds of Norway spruce.
- Observation In maturing seeds, the hybridization signal was found in the entire female gametophyte.
- Observation A strong signal was seen in the spongy tissue surrounding the female gametophyte of early ovules.
- Observation The in situ high signal corresponded well with results from Northern analyses.
- Observation A strong hybridization signal was seen in root tips of plants of various ages, including lateral roots and adventitious roots.
- Observation Columella cells of the root cap and guard cells of stomata in needles stained intensely.
- Observation A gene transcript identical to mipfg was identified in somatic embryos of Norway spruce.
- Mechanism Aquaporin function is indicated to have important roles in regulating transmembrane water and solute transport in Norway spruce.
