Resetting of a tandem microRNA156 enables vegetative perennial growth in rice

Bingxin Dai, Danfeng Lv, Erwang Chen, Zhoulin Gu et autres

Annual cultivated rice was domesticated from perennial wild rice, yet the genetic mechanism of perennial growth habit remains unclear. Using introgression lines of wild and cultivated rice, we identified the Endless Branches and Tillers ( EBT1 ) locus, comprising tandem microRNA156 genes …

A pangenome reference of wild and cultivated rice

Dongling Guo, Yán Li, Hengyun Lu, Yan Zhao et autres

Oryza rufipogon, the wild progenitor of Asian cultivated rice Oryza sativa, is an important resource for rice breeding1. Here we present a wild–cultivated rice pangenome based on 145 chromosome-level assemblies, comprising 129 genetically diverse O. rufipogon accessions and 16 diverse varieties of …

SHATTERING ABORTION3 controls rice seed shattering by promoting abscission zone separation

Danfeng Lv, Bingxin Dai, Yan Zhou, Yan Zhao et autres

The selection of non-shattering seeds has been a primary target during crop domestication, making wild rice suitable for human cultivation. Seed shattering involves development and separation of the abscission zone (AZ). The AZ consists of several layers of thin-walled, iso-diametrically flattened cells, …

Dynamics of extrachromosomal circular DNA in rice

Jundong Zhuang, Yaoxin Zhang, Congcong Zhou, Danlin Fan et autres

The genome's dynamic nature, exemplified by elements like extrachromosomal circular DNA (eccDNA), is crucial for biodiversity and adaptation. Yet, the role of eccDNA in plants, particularly rice, remains underexplored. Here, we identify 25,598 eccDNAs, unveiling the widespread presence of eccDNA across six …

Structure and function of rice hybrid genomes reveal genetic basis and optimal performance of heterosis

Zhoulin Gu, Junyi Gong, Zhou Zhu, Zhen Li et autres

Exploitation of crop heterosis is crucial for increasing global agriculture production. However, the quantitative genomic analysis of heterosis was lacking, and there is currently no effective prediction tool to optimize cross-combinations. Here 2,839 rice hybrid cultivars and 9,839 segregation individuals were resequenced …

The WD40 domain-containing protein Ehd5 positively regulates flowering in rice ( Oryza sativa )

Xuening Zhang, Qi Feng, Jiashun Miao, Jingjie Zhu et autres

Heading date (flowering time), which greatly influences regional and seasonal adaptability in rice (Oryza sativa), is regulated by many genes in different photoperiod pathways. Here, we characterized a heading date gene, Early heading date 5 (Ehd5), using a modified bulked segregant analysis …

Armadillo repeat only protein GS10 negatively regulates brassinosteroid signaling to control rice grain size

Erwang Chen, Qingqing Hou, Kun Liu, Zhoulin Gu et autres

Grain yield and grain quality are major determinants in modern breeding controlled by many quantitative traits loci (QTLs) in rice (Oryza sativa). However, the mechanisms underlying grain shape and quality are poorly understood. Here, we characterize a QTL for grain size and …

Chromosome-scale assembly and analysis of biomass crop Miscanthus lutarioriparius genome

Jiashun Miao, Qi Feng, Yan Li, Qiang Zhao et autres

Miscanthus, a rhizomatous perennial plant, has great potential for bioenergy production for its high biomass and stress tolerance. We report a chromosome-scale assembly of Miscanthus lutarioriparius genome by combining Oxford Nanopore sequencing and Hi-C technologies. The 2.07-Gb assembly covers 96.64% of the …
