Here, we integrate multi-environment phenotypes, environmental variables, and genomic data from 456 maize inbred lines and 912 corresponding hybrids evaluated across 11 environments to dissect the environmental and genetic bases of plasticity for flowering time, plant height, and ear weight. Reaction-norm analyses reveal two- to three-fold greater plasticity variation in inbreds than hybrids, indicating more uniform plastic responses in hybrids. Environmental association analyses demonstrate that inbreds and hybrids respond to the same environmental factors with different magnitudes or even opposite directions (e.g., correlations between diurnal temperature range and flowering time ranged from -0.73 to -0.14 in inbreds but 0.22 to 0.46 in hybrids). Genome-wide association analyses identify distinct parental loci for plasticity, with more loci and larger effects in hybrids. Functional validation shows that ZmBAF60_13, a chromatin-remodeling gene found only in the inbred panel, negatively regulates flowering-time plasticity. Integrating multiple environmental indices improves phenotype prediction accuracy by up to 16% over single-index models. Together, this study reveals that hybrids exhibit reduced plasticity variation and differ from inbreds in environmental responses and genetic associations, providing a framework for predicting crop performance under climate variability.</p>","PeriodicalId":54825,"journal":{"name":"Journal of Genetics and Genomics","volume":" ","pages":""},"PeriodicalIF":7.9,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149327594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although tumor-intrinsic resistance pathways have been mapped, how immune pressure regulates death-receptor vulnerability and anti-apoptotic buffering remains less defined. Using genome-wide CRISPR-Cas9 screening in cancer cells co-cultured with natural killer (NK) cells, we identify CFLAR, encoding cFLIP, as a dominant suppressor of death-receptor signaling that impairs NK- and T-cell cytotoxicity. CFLAR depletion sensitizes cancer cells to NK- and T-cell attack in vitro and in vivo. Single-cell and spatial transcriptomic analyses link high CFLAR expression to reduced lymphocyte infiltration and poorer responses to immune checkpoint blockade. Mechanistically, immune effector cell-induced inflammation increases CFLAR and death receptor 5 (DR5) expression in association with p38-MAPK signaling, balancing survival and death under immune pressure. The DR5 agonist conatumumab enhances lymphocyte-mediated killing and improves responses to cellular therapies, checkpoint blockade, and chemo-immunotherapy. Combining DR5 agonism with NKG2A blockade co-activates NK- and T-cell responses and overcomes anti-PD-1 resistance in MHC-I-deficient tumors.

Rather than an isolated tag, it acts as a spatiotemporal routing signal within an integrated post-translational modification (PTM) network, engaging in three defined crosstalk modes with ubiquitination and phosphorylation: synergistic, antagonistic, and cascading. Although crosstalk with acetylation and myristoylation exists, this review focuses on the ubiquitination- and phosphorylation-centered networks most directly linked to palmitoylation in disease. The same palmitoylation event can stabilize or destabilize substrates, or activate or silence signaling, depending on the specific Zinc finger DHHC domain-containing protein (ZDHHC) isoform, subcellular location, local enzyme availability, and metabolic state. We further introduce the \"PTM context signature\", a four-variable predictive framework for disease-specific crosstalk outcomes. By dissecting palmitoylation-centered crosstalk through a disease-oriented lens, we examine how its dysregulation drives oncogenesis, inflammation, metabolic disorders, and neurodegeneration. We then translate these mechanistic principles into a network-centric therapeutic framework, evaluating ZDHHC-directed modulators, peptide-based interface disruptors, and crosstalk-informed combinations that target context-specific nodes and anticipate therapy resistance.

Increasing evidence indicates that WAI arises from dysregulation of immune homeostasis across multiple regulatory levels, involving receptor activation, cellular homeostasis, and membrane transport processes, ultimately converging on evolutionarily conserved defense outputs such as reactive oxygen species (ROS) accumulation, activation of defense-related genes, ion fluxes, and programmed cell death (PCD). Recent advances have identified key WAI-associated loci, including nucleotide-binding and leucine-rich-repeat receptors (NLRs), membrane proteins, regulatory components, and transporters, revealing mechanistically distinct pathways underlying constitutive immunity and its trade-off with growth. This review summarizes recent progress in the genetics and molecular mechanisms of WAI, critically assesses its roles in broad-spectrum, multi-disease resistance, and discusses strategies to minimize the growth and fitness costs.
