From phenome to genome: A cloud-based AI platform for integrative rice grain analysis and genetic mapping to empower grain-focused crop improvement

Jie Zhou, Ahong Wang, Yan Zhao, Min Zhang et autres

Rice ( Oryza sativa L. ) is a staple crop of global importance. Accurate assessment of yield-related traits is essential for improving productivity and ensuring global food security. To address the limitations of labour-intensive and often subjective manual grain-based phenotyping, we developed …

Phospholipid remodeling interplays with auxin signaling to modulate cellular reprogramming in Arabidopsis regeneration

Pengjie Chang, Xiaomin Yang, X H Liu, Shiqi Guo et autres

In vitro regeneration of plants from tissues such as leaf or root explants typically starts with auxin-induced formation of a pluripotent cell mass termed callus. This cellular reprogramming is essential for the subsequent regeneration of shoots or roots. However, whether or how …

Three-Line Hybrid Rice in China: Fifty Years of Sustained Improvement in Yield, Quality, and Stress Resistance

Junyi Gong, Xiaobo Zhang, Jianfu Zhang, Bo Zeng et autres

China pioneered the commercial application of hybrid rice ( Oryza sativa L.) throughout the world. Not only did Chinese scientists demonstrate that self-pollinating plants can achieve hybrid vigor, which was a groundbreaking theoretical breakthrough; they also established commercial rice breeding as one …

Enhancer Extrachromosomal Circular DNA ANKRD28 Elicits Drug Resistance via POU2F2‐Mediated Transcriptional Network in Multiple Myeloma

Binzhen Chen, Jia Liu, Yaoxin Zhang, Changming Shih et autres

Multiple myeloma (MM) remains an incurable disease primarily due to the emergence of drug resistance, and the underlying mechanisms remain unclear. Extrachromosomal circular DNAs (eccDNAs) are prevalent in cancer genomes of both coding and non-coding regions. However, the role of non-coding eccDNA …

Unlocking the mystery of heterosis opens the era of intelligent rice breeding

Zhoulin Gu, Bin Han

Heterosis refers to the phenomenon where the first filial offspring (F1) from genetically diverse parents displays advantages in growth rate, yield, and adaptability compared with its parents. The exploitation of heterosis in rice breeding has greatly increased the productivity, making a significant …

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 …

A higher‐yield hybrid rice is achieved by assimilating a dominant heterotic gene in inbred parental lines

Changsheng Wang, Ziqun Wang, Yunxiao Cai, Zhou Zhu et autres

Summary The exploitation of heterosis to integrate parental advantages is one of the fastest and most efficient ways of rice breeding. The genomic architecture of heterosis suggests that the grain yield is strongly correlated with the accumulation of numerous rare superior alleles …

High-throughput UAV-based rice panicle detection and genetic mapping of heading-date-related traits

R. F. Chen, Hengyun Lu, Yongchun Wang, Qilin Tian et autres

Introduction: ) serves as a vital staple crop that feeds over half the world's population. Optimizing rice breeding for increasing grain yield is critical for global food security. Heading-date-related or Flowering-time-related traits, is a key factor determining yield potential. However, traditional manual …

Dysfunction of duplicated pair rice histone acetyltransferases causes segregation distortion and an interspecific reproductive barrier

Ben Liao, You-Huang Xiang, Yan Li, Kai-Yang Yang et autres

Abstract Postzygotic reproductive isolation, which results in the irreversible divergence of species, is commonly accompanied by hybrid sterility, necrosis/weakness, or lethality in the F1 or other offspring generations. Here we show that the loss of function of HWS1 and HWS2, a couple …
