Figure 2. Developmental analysis of gnt1.[1].
Function
- Oryza sativa GnTI encodes enzymatically and functionally active protein
- Loss of GnTI function resulted in decreased cell wall synthesis activity, which might be responsible for the brittle phenotype and reduced tensile strength in gnt1.
- GnTI plays an important role in cellulose biosynthesis in the plant.
Phenotypic analysis
- Phenotypic analyses revealed that gnt1 shows defective post-seedling development and incomplete cell wall bio-synthesis, leading to symptoms such as failure in tiller formation, brittle leaves, reduced cell wall thickness, and decreased cellulose content.
- The developmental defects of gnt1 ultimately resulted in early lethality without transition to the reproductive stage.
- However, callus induced from gnt1 seeds could be maintained for periods, although it exhibited a low proliferation rate, small size, and hypersensitivity to salt stress.
- Shoot regeneration and dark-induced leaf senescence assays indicated that the loss of GnTI function results in reduced sensitivity to cytokinin in rice.
- Reduced expression of A-type O. sativa response regulators that are rapidly induced by cytokinins in gnt1 confirmed that cytokinin signaling is impaired in the mutant.
