JMJ720 regulates flowering time in rice via H3K9 demethylation of Hd1

Xiufeng Li, Jiaping Zhu, Xiaojie Tian, Yingxiang Liu et autres

Heading date is a crucial agronomic trait that determines the adaptability of rice to specific planting regions and seasons. Although numerous heading date genes have been well characterized in rice, epigenetic regulation of flowering time remains limited. In this study, we identified …

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

Gai Huang, Xiaofei Wang, Chengli Liu, Kaixuan He et autres

Halophytes possess inherent stress resilience and diverse adaptations, making them valuable genetic reservoirs for crop breeding. The leguminous halophyte Sesbania bispinosa is a valuable forage crop that thrives in saline soils. To explore its salt tolerance, high-quality genome assemblies is generated for …

Inheritance of acquired adaptive cold tolerance in rice through DNA methylation

Xianwei Song, Shanjie Tang, Hui Liu, Ying Meng et autres

Epigenetic pathways could provide a mechanistic explanation for the inheritance of acquired characteristics, as proposed by Lamarck in 1802, but epigenetic alterations that endow adaptive hereditary traits have rarely been observed. Here, in cultivated Asian rice (Oryzasativa L.), we identified an epiallele …

tRNA selectivity during ribosome-associated quality control regulates the critical sterility-inducing temperature in two-line hybrid rice

Can Zhou, Chunyan Liu, Bin Yan, Jing Sun et autres

The two-line hybrid rice system, a cutting-edge hybrid rice breeding technology, has greatly boosted global food security. In thermo-sensitive genic male sterile (TGMS) lines, the critical sterility-inducing temperature (CSIT; the temperature at which TGMS lines change from male fertile to complete male …

The E3 ligase OsHel2 impedes readthrough of stalled mRNAs to regulate male fertility in thermosensitive genic male sterile rice

Wei Liu, Ji Li, Jun Sun, Chunyan Liu et autres

Heterosis is extensively used in the 2-line hybrid breeding system. Photosensitive/thermosensitive genic male sterile (P/TGMS) lines are key components of 2-line hybrid rice, and TGMS lines containing tms5 have significantly advanced 2-line hybrid rice breeding. We cloned the TMS5 gene and found …

Acyl carrier protein OsMTACP2 confers rice cold tolerance at the booting stage

Xiuli Hou, Xiangyan Han, L.L. Wang, Wenqi Zhang et autres

Low temperatures occurring at the booting stage in rice (Oryza sativa L.) often result in yield loss by impeding male reproductive development. However, the underlying mechanisms by which rice responds to cold at this stage remain largely unknown. Here, we identified MITOCHONDRIAL …

Dynamic root microbiome sustains soybean productivity under unbalanced fertilization

Mingxing Wang, An‐Hui Ge, Xingzhu Ma, Xiaolin Wang et autres

Root-associated microbiomes contribute to plant growth and health, and are dynamically affected by plant development and changes in the soil environment. However, how different fertilizer regimes affect quantitative changes in microbial assembly to effect plant growth remains obscure. Here, we explore the …

Blocking miR528 function promotes tillering and regrowth in switchgrass

Xiangyan Han, Shanjie Tang, Xuan Ma, Wenwen Liu et autres

MiRNAs have been reported to be the key regulators involving a wide range of biological processes in diverse plant species, but their functions in switchgrass, an important biofuel and forage crop, are largely unknown. Here, we reported the novel function of miR528, …

A mitochondrial pentatricopeptide repeat protein enhances cold tolerance by modulating mitochondrial superoxide in rice

Xiaofeng Zu, Lilan Luo, Zhen Wang, Jie Gong et autres

Cold stress affects rice growth and productivity. Defects in the plastid-localized pseudouridine synthase OsPUS1 affect chloroplast ribosome biogenesis, leading to low-temperature albino seedlings and accumulation of reactive oxygen species (ROS). Here, we report an ospus1-1 suppressor, sop10. SOP10 encodes a mitochondria-localized pentatricopeptide …

Genome evolution and initial breeding of the Triticeae grass Leymus chinensis dominating the Eurasian Steppe

Tong Li, Shanjie Tang, Wei Li, Shuaibin Zhang et autres

Leymus chinensis , a dominant perennial grass in the Eurasian Steppe, is well known for its remarkable adaptability and forage quality. Hardly any breeding has been done on the grass, limiting its potential in ecological restoration and forage productivity. To enable genetic …
