The YABBY gene DROOPING LEAF regulates carpel specification and midrib development in Oryza sativa.
In this article, we report that carpel specification in the Oryza sativa (rice) flower is regulated by the floral homeotic gene DROOPING LEAF (DL) that is distinct from the well-known ABC genes. Severe loss-of-function mutations of DL cause complete homeotic transformation of carpels into stamens. Molecular cloning reveals that DL is a member of the YABBY gene family and is closely related to t...

متن کاملGenome-wide expression profiling and identification of genes under the control of the DROOPING LEAF gene during midrib development in rice.
The DROOPING LEAF (DL) gene has an important function in rice development. Loss-of-function mutation of DL fails to form midrib, a strong structure formed in the central region of the leaf, resulting in a drooping leaf phenotype. In addition, severe mutation in DL causes a floral homeotic change, i.e., replacement of the carpels by the stamens. Thus, DL regulates midrib formation in the leaf an...
متن کاملGeneration of artificial drooping leaf mutants by CRISPR-Cas9 technology in rice.
CRISPR-Cas9 technology, which uses an RNA-guided nuclease, has been developed as an efficient and versatile genome-editing method to induce mutations in genes of interest. To examine the feasibility of this method in developmental studies of a model monocot, rice (Oryza sativa), we introduced the construct gDL-1, which produced a guide RNA targeting the DROOPING LEAF (DL) gene. DL regulates mid...
متن کاملCharacterization and gene cloning of the rice (Oryza sativa L.) dwarf and narrow-leaf mutant dnl3.
The dwarf and narrow-leaf rice (Oryza sativa L.) mutant dnl3 was isolated from the Japonica cultivar Zhonghua 11 (wild-type). dnl3 exhibited pleiotropic developmental defects. The narrow-leaf phenotype resulted from a marked reduction in the number of vascular bundles, while the dwarf stature was caused by the formation of foreshortened internodes and a reduced number of parenchyma cells. The s...
