Bryophyte ELIPs as Evolutionary Guardians: Engineering Chloroplast Resilience and ABA-Enhanced Drought Tolerance in Crops.

Early light-induced proteins (ELIPs) are pivotal for plant stress adaptation, yet their evolutionary and functional diversification across land plants remain unclear. Here, 454 ELIPs genes from 15 species (chlorophytes to angiosperms) were analysed using phylogenomics, cis-regulatory element mapping, transcriptomics, and transgenic validation. Phylogenetics classified ELIPs into four groups: Group 1 exclusive to non-seed plants (e.

Genome-wide characterization of C2H2 zinc-finger gene family provides insight into the mechanisms and evolution of the dehydration-rehydration responses in and .

Dehydration tolerance is a vital factor for land plant evolution and world agricultural production. Numerous studies enlightened that the plant-specific C2H2-type zinc-finger proteins (C2H2-ZFPs) as master regulators played pivotal roles in the abiotic stress responses of plants. However, a comprehensive understanding of the evolution of C2H2-ZFPs in terrestrial plants and its regulatory mechanism in dehydration and rehydration response remains a mystery.

Gold nanoclusters as fluorescent sensors for selective and sensitive hydrogen sulfide detection.

As a highly toxic environmental pollutant and also an important gasotransmitter in diverse physiological processes, the selective and sensitive detection of hydrogen sulfide (HS) is very significant. In this work, acetylcysteine stabilized gold nanoclusters (ACC@AuNCs)-based fluorescent sensors had been successfully constructed for HS perception. The sensing principle was that HS-induced fluorescence quenching of AuNCs which attributed to both the formation of AuS between Au(I) in the AuNCs and HS and the increased particle size.
