Mashup Score: 36An enhancer–promoter-transcription factor module orchestrates plant immune homeostasis by constraining camalexin biosynthesis - 5 day(s) ago
During immune activation in Arabidopsis thaliana, the enhancer CORE PATTERN-INDUCED ENHANCER 35 (CPIE35) activates the transcription of WRKY15 by forming chromatin loops with the promoter of WRKY15 in a WRKY18/40/60-, WRKY33-, and MYC2-dependent manner. WRKY15, in turn, suppresses the expression of PAD3 and GSTU4, inhibiting camalexin synthesis and therefore decreasing plant resistance to pathogenic fungi. Notably, the CPIE35 region is evolutionarily conserved among Brassicaceae plants, and the CPIE35-WRKY15 module exerts similar functions in Brassica napus to negatively regulate antifungal resistance.

Mashup Score: 4Molecular and cellular mechanisms of photoperiod- and thermo-sensitive genic male sterility in plants - 10 day(s) ago
Photoperiod-and thermo-sensitive genic male sterility (P/TGMS) is crucial for two-line hybrid breeding in crops. This review highlights the molecular, cellular, and genetic mechanisms underlying anther and pollen development in P/TGMS lines, dissects the roles of slow development and ROS homeostasis in fertility restoration, and discusses future applications of P/TGMS and potential solutions to the challenges in this field.

Mashup Score: 2SCOOP10 and SCOOP12 peptides act through MIK2 receptor-like kinase to antagonistically regulate Arabidopsis leaf senescence - 2 month(s) ago
This study reveals that two peptides from the SERINE-RICH ENDOGENOUS PEPTIDE family, specifically SCOOP10 and SCOOP12, bind to the Receptor-Like Kinase (RLK) MIK2 and antagonistically regulate the progression of leaf senescence in Arabidopsis. The results highlight a complex and tightly controlled mechanism that governs leaf aging.

Mashup Score: 5Dynamic modulation of nodulation factor receptor levels by phosphorylation-mediated functional switch of a RING-type E3 ligase during legume nodulation - 2 month(s) ago
Nodulation factor (NF) receptors NFR1/NFR5 recognize rhizobial NFs to initiate symbiotic signal transduction in legume–rhizobium symbiosis. However, the mechanisms underlying NFR1/NFR5-mediated perception of NFs to establish symbiosis remain unclear. This work demonstrates that a RING-type E3 ligase dynamically modulates NFR1/NFR5 levels via a phosphorylation-mediated functional switch during legume nodulation.

Mashup Score: 16Dual roles of the Arabidopsis PEAT complex in histone H2A deubiquitination and H4K5 acetylation - 9 month(s) ago
This study identifies the Arabidopsis ubiquitin-specific protease UBP5 as a major histone H2A deubiquitinase and demonstrates that it serves as a subunit of PEAT complex. The PWWP and EPCR components of the PEAT complex are involved in UBP5-mediated H2A deubiquitination and HAM1/2-mediated histone H4K5 acetylation, respectively, revealing dual roles of the PEAT complex in H2A deubiquitination and H4K5 acetylation.

Mashup Score: 7Plant RNA-binding proteins: Phase separation dynamics and functional mechanisms underlying plant development and stress responses - 9 month(s) ago
This review discusses the phase separation dynamics of RNA-binding protein (RBP)-rich condensates and the mechanisms by which they control plant development and sense experimental changes to confer growth plasticity under stress conditions. The roles of multiple factors in modulating the phase separation behaviors of RBPs are also discussed, and the prospects and challenges for future research on phase-separating RBPs in crops are highlighted.

Mashup Score: 7Rice roots avoid asymmetric heavy metal and salinity stress via an RBOH-ROS-auxin signaling cascade - 1 year(s) ago
Abiotic stressors, such as heavy metals and salt, are distributed heterogeneously in soil. How plant roots respond to unevenly distributed stressors remains unclear. In this study, we identified an RBOH-ROS-auxin signaling cascade that enables rice roots to avoid localized heavy metals and salt through remodeling of the root system architecture.

Mashup Score: 6
Stress-tolerant crop varieties for cultivation in innovative cropping systems will be crucial under climate-changed environments. A survey of 588 experts predicted traits that will be essential for pearl millet, sorghum, maize, groundnut, cowpea, and common bean, particularly in sub-Saharan Africa. This review discusses the status of breeding and novel approaches to use genetic resources for the prioritized traits, and concludes that the greatest challenge to developing varieties to win the race between climate change and food security will be our foresight in defining, and boldness to prioritize breeding for future-essential traits.
