Abstract Anthropogenically caused nitrogen (N) enrichment may stimulate both photosynthetic carbon (C) fixation and infection of foliar pathogens. However, the interactive effects N input fungal pathogens on ecosystem C cycling are poorly understood. Using a 6‐year field experiment with fungicide application in Tibetan alpine meadow, we examined how influence sequestration independently combination, possibly resulting interactions between Nitrogen increased gross productivity (GEP) respiration (ER) through increasing plant biomass content but did not affect net (NEP).

Abstract Viola philippica develops chasmogamous (CH) and cleistogamous (CL) flowers under different photoperiods, while cornuta only forms CH flowers. Gene expression variations driven by photoperiods that contribute to the CH–CL transition remain largely unknown. Here, we performed comparative transcriptomics between V . during flower development revealed differentially expressed genes (DEGs) CL Compared in 16‐h daylight conditions, DEGs, including auxin response factor (ARF) floral MADS‐box genes, were identified 12‐h conditions; however, their homologous equivalently across both photoperiods. Genes modules most significantly correlated with types DEGs , but they not altered either photoperiod. Moreover, related fatty acid, flavonoid, anthocyanin biosynthesis upregulated flowers, whereas defense Furthermore, co‐expressed B‐class gene APETALA3 included ARFs CRABS CLAW BIGPETALp TCP14 UGT87A whose are involved nectary organ development, identity, size, coloration. Thus, putative coordination of signaling pathways, identity determination growth, acid flavonol photoperiod might regulate thus providing new insights into evolution dimorphic

Various pathogens severely threaten tomato yield and quality. Advances in understanding plant-pathogen interactions have revealed the intricate roles of resistance (R) susceptibility (S) genes determining plant immunity. While R provide targeted pathogen resistance, they are often vulnerable to evolution. Conversely, S offer a promising avenue for developing broad-spectrum durable through gene editing. Recent breakthroughs CRISPR/Cas-based technologies revolutionized manipulation genomes, enabling precise modification enhance disease without compromising growth or However, utilization full potential this technique is challenging due complex current technological limitations. This review highlights key advances using editing tools dissect engineer improved We discuss how influence entry, immune suppression, nutrient acquisition, their has conferred bacterial, fungal, viral pathogens. Furthermore, we address challenges associated with growth-defense trade-offs propose strategies, such as hormonal pathway modulation regulatory edits, overcome these underscores CRISPR-based approaches transform breeding, paving way sustainable production disease-resistant cultivars amidst escalating global food security challenges.

ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how in Phaseolus vulgaris influences the behaviour performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R + ) vs. non‐nodulated − roots assessed impact growth. also analysed root nutrient content volatile organic compounds (VOCs) to identify potential chemical cues driving feeding preferences. Larvae strongly preferred R roots, where they exhibited enhanced growth higher survival post‐metamorphosis. Nutritional analysis revealed that had greater content, supporting improved performance. VOC profiles differed significantly treatments, olfactometer assays confirmed attraction was mediated by VOCs, likely signalling nutritional benefits from symbiosis. Our results demonstrate rhizobia‐induced metabolic changes bean make them more attractive nutritious herbivorous This highlights a complex belowground interaction bacteria, host herbivores, with implications ecological theory sustainable agriculture. Understanding these interactions could inform pest management strategies improve legume cultivation balancing plant–microbe mutualisms herbivore dynamics.

Abstract Anthracnose, caused by Colletotrichum sublineola , is a prevalent disease that noticeably affects global sorghum production. Nucleotide-binding leucine-rich repeat receptors (NLRs) are crucial for resistance. Here, we report the differences in number, expression profile, and gene structure of NLRs between anthracnose-resistant susceptible cultivars. Through systematic anthracnose assay on 365 accessions, identified American improved cultivar BTx623 as resistant Chinese glutinous Guojiaohong1 (GJH1) cultivar. Then sequenced genome GJH1 239 NLRs, substantially fewer than 302 BTx623. Although collinear highly conserved BTx623, more half non-collinear showed notable mutations or structural variations. During C. infection, exhibited higher number expressed inducible NLR genes did. Moreover, some candidate resistance potentially valuable disease-resistant breeding. Therefore, our data provide genetic resources developing sorghum.

The OsTHION family represents a class of cysteine-rich signal peptides widely recognized for their significant roles in plant disease resistance and immunity. While members this are known to be induced under various biotic abiotic stresses, responses environmental stressors beyond remain underexplored. This study investigates the evolution, expression patterns, functional gene rice (Oryza sativa) diverse stress conditions. Using sequence data from Phytozome database, we identified 44 classified them into four groups based on phylogenetic analysis. Cis-acting element analysis revealed that promoter regions genes enriched with regulatory elements associated light response, hormone signaling, growth, responses. exhibit complex organ-specific OsTHION30 OsTHION36 showing ubiquitous expression, while other highly expressed specific tissues or developmental stages. Under drought, salt, low-temperature stress, undergo changes, underscoring critical role adaptation challenges. Notably, OsTHION15 was markedly upregulated drought Osthion15 mutant displayed heightened sensitivity ABA confirming its pivotal resistance. RNA sequencing many differentially (DEGs), primarily pathways related ribosomal function suggesting may regulate through multiple mechanisms. In summary, advances our understanding highlights intricate involvement regulating development, These findings offer valuable insights technical support crop improvement, potential applications enhancing adaptability yield stability crops.
