molecular mechanisms underlying Plant Architecture and its environmental plasticity in rice
Molecular Breeding, 2019Co-Authors: Hengbin Gao, Yonghong Wang, Wenguang Wang, Yan LiangAbstract:Plant Architecture, which consists mainly of Plant height, tillering, and panicle morphology, contributes greatly to grain yield in rice. Exploring the molecular mechanisms of rice Plant Architecture will provide theoretical guidance and valuable gene resources for breeding elite rice varieties with ideal Plant Architecture. In this review, we emphasize recent progress in elucidating the mechanisms that control rice Plant Architecture, focusing on tiller number, tiller angle, and panicle branching. Environmental factors influence the plasticity of rice Plant Architecture, and thus we also discuss the roles of environmental factors in regulating rice Plant Architecture.

tissue specific ubiquitination by ipa1 interacting protein1 modulates ipa1 protein levels to regulate Plant Architecture in rice
The Plant Cell, 2017Co-Authors: Yongqing Jiao, Zefu Lu, Yonghong Wang, Jian Wang, Hong Yu, Guosheng Xiong, Xiangbing Meng, Xuewei Chen, Jiayang LiAbstract:Plant Architecture, a collection of genetically controlled agronomic traits, is one of the decisive factors that determine grain production. IDEAL Plant Architecture 1 (IPA1) encodes a key transcription factor having pleiotropic effects on regulating Plant Architecture in rice (Oryza sativa), and IPA1 expression is controlled at the post-transcriptional level by microRNA156 and microRNA529. Here, we report the identification and characterization of IPA1 INTERACTING PROTEIN 1 (IPI1), a RING-finger E3 ligase that can interact with IPA1 in the nucleus. IPI1 promotes the degradation of IPA1 in panicles while it stabilizes IPA1 in shoot apexes. Consistent with these findings, the ipi1 loss-of-function mutants showed markedly altered Plant Architecture, including more tillers, enlarged panicles, and increased yield per Plant. Moreover, IPI1 could ubiquitinate IPA1-mediated complex with different polyubiquitin chains, adding K48-linked polyubiquitin chains in panicles and K63-linked polyubiquitin chains in the shoot apex. These results demonstrate that IPI1 affects Plant Architecture through precisely tuning IPA1 protein levels in different tissues in rice, and provide new insight into the tissue-specific regulation of Plant Architecture and important genetic resources for molecular breeding applications.

Regulation of OsSPL14 by OsmiR156 defines ideal Plant Architecture in rice
Nature Genetics, 2010Co-Authors: Yongqing Jiao, Meixian Yan, Guifu Liu, Dawei Xue, Zefu Lu, Dali Zeng, Yonghong Wang, Guojun Dong, Jing Wang, Xudong ZhuAbstract:Increasing crop yield is a major challenge for modern agriculture. The development of new Plant types, which is known as ideal Plant Architecture (IPA), has been proposed as a means to enhance rice yield potential over that of existing high-yield varieties. Here, we report the cloning and characterization of a semidominant quantitative trait locus, IPA1 (Ideal Plant Architecture 1), which profoundly changes rice Plant Architecture and substantially enhances rice grain yield. The IPA1 quantitative trait locus encodes OsSPL14 (SOUAMOSA PROMOTER BINDING PROTEIN-LIKE 14) and is regulated by microRNA (miRNA) OsmiR156 in vivo. We demonstrate that a point mutation in OsSPL14 perturbs OsmiR156-directed regulation of OsSPL14, generating an 'ideal' rice Plant with a reduced tiller number, increased lodging resistance and enhanced grain yield. Our study suggests that OsSPL14 may help improve rice grain yield by facilitating the breeding of new elite rice varieties.

Molecular Basis of Plant Architecture
Annual Review of Plant Biology, 2008Co-Authors: Yonghong Wang, Jiayang LiAbstract:Higher Plants display a variety of Architectures that are defined by the degree of branching, internodal elongation, and shoot determinancy. Studies on the model Plants of Arabidopsis thaliana and tomato and on crop Plants such as rice and maize have greatly strengthened our understanding on the molecular genetic bases of Plant Architecture, one of the hottest areas in Plant developmental biology. The identification of mutants that are defective in Plant Architecture and characterization of the corresponding and related genes will eventually enable us to elucidate the molecular mechanisms underlying Plant Architecture. The achievements made so far in studying Plant Architecture have already allowed us to pave a way for optimizing the Plant Architecture of crops by molecular design and improving grain productivity.

An auxin signaling gene BnaA3.IAA7 contributes to improved Plant Architecture and yield heterosis in rapeseed.
The New phytologist, 2019Co-Authors: Jurong Song, Jing Wang, Bo Wang, Bo Zhao, Chaocheng Guo, Qinghua Zhang, Graham J.w. King, Kede LiuAbstract:Plant Architecture is the key factor affecting overall yield in many crops. The genetic basis underlying Plant Architecture in rapeseed (Brassica napus), a key global oil crop, is elusive. We characterized an ethyl methanesulfonate (EMS)-mutagenized rapeseed mutant, sca, which had multiple phenotypic alterations, including crinkled leaves, semi-dwarf stature, narrow branch angles and upward-standing siliques. We identified the underlying gene, which encodes an Aux/IAA protein (BnaA3.IAA7). A G-to-A mutation changed the glycine at the 84th position to glutamic acid (G84E), disrupting the conserved degron motif GWPPV and reducing the affinity between BnaA3.IAA7 and TIR1 (TRANSPORT INHIBITOR RESPONSE 1) in an auxin dosage-dependent manner. This change repressed the degradation of BnaA3.IAA7 and therefore repressed auxin signaling at low levels of auxin that reduced the length of internodes. The G84E mutation reduced branch angles by enhancing the gravitropic response. The heterozygote +/sca closely resembled a proposed ideal Plant Architecture, displaying strong yield heterosis through single-locus overdominance by improving multiple component traits. Our findings demonstrate that a weak gain-of-function mutation in BnaA3.IAA7 contributes to yield heterosis by improving Plant Architecture and would be valuable for breeding superior rapeseed hybrid cultivars and such a mutation may increase the yield in other Brassica crops.
