Generation 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 کاملSUPERWOMAN1 and DROOPING LEAF genes control floral organ identity in rice.
We analyzed recessive mutants of two homeotic genes in rice, SUPERWOMAN1 (SPW1) and DROOPING LEAF (DL). The homeotic mutation spw1 transforms stamens and lodicules into carpels and palea-like organs, respectively. Two spw1 alleles, spw1-1 and spw1-2, show the same floral phenotype and did not affect vegetative development. We show that SPW1 is a rice APETALA3 homolog, OsMADS16. In contrast, two...
متن کاملThe 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 کاملGenetic interaction of OsMADS3, DROOPING LEAF, and OsMADS13 in specifying rice floral organ identities and meristem determinacy.
Grass plants develop unique floral patterns that determine grain production. However, the molecular mechanism underlying the specification of floral organ identities and meristem determinacy, including the interaction among floral homeotic genes, remains largely unknown in grasses. Here, we report the interactions of rice (Oryza sativa) floral homeotic genes, OsMADS3 (a C-class gene), OsMADS13 ...
