Pathogen-associated Molecular Pattern-triggered Immunity Involves Proteolytic Degradation of Core Nonsense-mediated mRNA Decay Factors During the Early Defense Response
UPF protein ubiquitination resistance gene Nonsense-mediated mRNA decay (NMD) Defense response Effective immunity
2024/1/22
Nonsense-mediated mRNA decay (NMD), an mRNA quality control process, has been implicated in plant immunity. A subset of fully spliced (FS) transcripts of Arabidopsis resistance (R) genes are reportedl...
Vegetation Determines Lake Sediment Carbon Accumulation during Holocene in the Forest–Steppe Ecotone in Northern China
carbon accumulation rate (CAR) Huangqihai Lake climate change vegetation coverage broadleaved forest Holocene
2023/12/19
To understand the past carbon accumulation of forest–steppe ecotone and to identify the main drivers of the long-term carbon dynamics, we selected Huangqihai Lake and analyzed the sediment records. We...
Cytokinins as central regulators during plant growth and stress response
Cytokinin Biosynthesis and metabolism Signaling and gene regulation Plant growth Abiotic stress response
2023/12/19
Cytokinins are a class of phytohormone that participate in the regulation of plant growth, physiological activities, and yield. Cytokinins also play a key role in response to abiotic stresses, such as...
Monitoring of XRN4 Targets Reveals the Importance of Cotranslational Decay during Arabidopsis Development
Arabidopsis XRN4 mRNA decay seedlingDevelopmen
2023/12/18
RNA turnover is a general process that maintains appropriate mRNA abundance at the posttranscriptional level. Although long thought to be antagonistic to translation, discovery of the 5? to 3? cotrans...
Developmental plasticity in Arabidopsis thaliana under combined cold and water deficit stresses during flowering stage
Acclimation Bolting Cold Flower size Terminal combined stress Water deficit
2023/12/11
In nature, plants are exposed to multiple and simultaneous abiotic stresses that influence their growth, development, and reproduction. In the last years, the study of combined stresses has aroused th...
Stomatal and mesophyll conductance are dominant limitations to photosynthesis in response to heat stress during severe drought in a temperate and a tropical tree species
High temperature Water deficit Water use efficiency Carbon exchange Vcmax
2023/12/6
Drought and heat stress cause a significant reduction in forest primary production. The current study aims to determine the major limitations to photosynthesis in a temperate and tropical tree species...
LARP6C orchestrates posttranscriptional reprogramming of gene expression during hydration to promote pollen tube guidance
LARP6C gene expression posttranscriptional regulation pollination fertilization
2023/12/1
Increasing evidence suggests that posttranscriptional regulation is a key player in the transition between mature pollen and the progamic phase (from pollination to fertilization). Nonetheless, the ac...
A MRG-operated chromatin switch at SOC1 attenuates abiotic stress responses during the floral transition
stress responses MORF-RELATED GENE (MRG) Arabidopsis plant fitness endogenous signals reproductive success
2023/12/1
Plants react to environmental challenges by integrating external cues with endogenous signals to optimize survival and reproductive success. However, the mechanisms underlying this integration remain ...
Live single-cell transcriptional dynamics via RNA labelling during the phosphate response in plants
RNA single-cell transcriptional dynamics phosphate response plant development
2023/12/1
Plants are constantly adapting to ambient fluctuations through spatial and temporal transcriptional responses. Here, we implemented the latest-generation RNA imaging system and combined it with microf...

宋庆鑫 水稻栽培 基因
2023/10/28
水稻是全球最为重要的粮食作物之一，在其漫长的驯化过程中形成了形态各异的水稻栽培亚型，包括粳稻、籼稻、Aro和Aus等。在水稻栽培种植历史过程中，有些水稻逐渐恢复部分野生稻表型特征，最终演化成严重威胁全球水稻产量的杂草稻，这种现象称之为“去驯化”。通过基因组进化研究发现，大量驯化位点的变异在去驯化过程中并不能得到恢复，这就暗示着可能存在别的遗传机制来调控杂草稻在去驯化过程中恢复野生稻表型。DNA甲基...
