Annotated Information
Gene Symbol
- Os05g0578900 <=> nl1, OsGATA15
Function
- The NL1 gene encodes a GATA-type transcription factor with a single zinc finger domain, and its transcripts are detected predominantly in the bract primordia, which normally degenerate in the wild-type plants.
- NL1 is an intrinsic factor that modulates and coordinates organogenesis through regulating the expression of PLA1 and other regulatory genes during reproductive development in rice.
Mutation
Figure 1 Mutants affecting the pattern formation during panicle development. [1].
- nl1 mutation results in delays in flowering time, smaller panicles with overgrown bracts and abnormal UPI elongation patterns.
Overexpression
- Overexpression of NL1 in transgenic plants often gives rise to severe growth retardation, less vegetative phytomers and smaller leaves, suggesting that NL1 plays an important role in organ differentiation.
Expression
- The researchers investigated NL1 temporal and spatial expression patterns. NL1 was strongly expressed in young inflorescences and weakly expressed in the roots and elongating internodes as shown by RT-PCR analysis.
