Cytoplasmic Histone Is a Marker of Pro-Inflammatory CD4 T Cells.

Although extranuclear histones have been identified for a long time, their role in lymphocytes, particularly cytoplasmic histones, remains elusive. In this study, we conducted a visual and quantitative analysis of cytoplasmic histones in CD4 T cells and discovered that effector CD4 T cells contain higher levels of cytoplasmic histones compared to naïve T cells. We observed a significant increase in cytoplasmic histones following T cell receptor (TCR) activation, with further elevation during the differentiation of Th1 and Th17 cells.

RcPLATZ8 as a novel negative regulator of flowering in Rosa chinensis.

Comprehensive analysis of the RcPLATZ gene family in Rosa chinensis reveals RcPLATZ8 as a novel negative regulator of flowering, offering insights for targeted breeding to manipulate flowering traits. Flowering regulation in Rosa chinensis is essential for improving ornamental and commercial traits, but its molecular mechanisms remain poorly understood. In this study, we identified and characterized ten members of the PLANT AT-RICH SEQUENCE AND ZINC-BINDING (PLATZ) protein family in R.

Phylogeny and Functional Differentiation of the Terpene Synthase Gene Family in Angiosperms with Emphasis on .

Terpenes are pivotal for plant growth, development, and adaptation to environmental stresses. With the advent of extensive genomic data and sophisticated bioinformatics tools, new insights into the evolutionary dynamics and functional diversification of terpene synthases (TPSs) have emerged. Despite genome-wide identifications of the TPS family in certain species, comprehensive cross-species analyses remain scarce.

[Cloning and expression analysis of the laccase gene from ].

Laccases (LACs), belonging to the multicopper oxidase family, are closely associated with various biological functions including lignin synthesis and responses to biotic and abiotic stresses in plants. However, few studies have reported the laccase genes in China rose (). Prickles cause difficulties to the management and harvest of .

Proteomic and Transcriptomic Responses of the Desiccation-Tolerant Moss in the Rapid Rehydration Processes.

The moss () has strong desiccation tolerance. It can remain desiccated for years and yet recover within minutes of rehydration. Understanding the responses and mechanisms underlying this rapid rehydration capacity in bryophytes could identify candidate genes that improve crop drought tolerance.

Identification and Characterization of Transcription Factors Involved in Geraniol Biosynthesis in .

Fragrance is an important characteristic of rose flowers and is largely determined by the terpenes. Rose has a unique NUDX1 (NUDIX HYDROLASES 1)-dependent monoterpene geraniol biosynthesis pathway, but little is known about its transcriptional regulation. In this study, we characterized two China rose () materials from the 'Old Blush' variety with contrasting aromas.
