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 ...
