Plants sense oscillation in the day length as a reliable seasonal cue to drive optimal vegetative and reproductive growth. A recent study by Yu et al. has revealed how day length regulates seed size through CONSTANS. The CONSTANS–APETALA2 module enables plants to optimize their reproductive growth based on their photoperiod response type. 相似文献

Globally, overuse of nitrogen (N) fertilizers in croplands is causing severe environmental pollution. In this context, Gu et al. suggest environmentally friendly and cost-effective N management practices and Hamani et al. highlight the use of microbial inoculants to improve crop yields, while reducing N-associated environmental pollution and N-fertilizer use. 相似文献

Plant nucleotide-binding leucine-rich repeat (NLR) receptors mediate specific recognition of pathogen effectors to initiate effector-triggered immunity. Recently, studies by Schulze et al., Yang et al., and Gu et al. collectively show that the Arabidopsis (Arabidopsis thaliana) NLR pair CHS3-CSA1 acts through two distinct activation modes to recognize different pathogen effectors, thus revealing the dual function of the CHS3-CSA1 pair in plant disease resistance. 相似文献

Diverse plant small peptides are perceived by their corresponding receptors to mediate local or long-distance intercellular communications in various developmental and adaptive programs; notably, the mechanisms of peptide–receptor perception remain largely unrevealed. Two reports (Liu et al.; Diaz-Ardila et al.) shed light on how pH regulates peptide–receptor perception. 相似文献

Bacteria synthesize specialized nucleotide signals to control anti-phage defense. Two papers – by Huiting et al. and Jenson et al. – now reveal that bacteriophages encode protein ‘sponges’ that sequester cyclic oligonucleotide immune signals and inactivate host antiviral immunity. 相似文献

Protein-based biological circuits enable customized control of cellular functions, and de novo protein design enables circuit functionalities that are not possible by repurposing natural proteins. Here, I highlight recent progress in protein circuit design, including CHOMP, developed by Gao et al., and SPOC, developed by Fink et al. 相似文献

Fungal pathogens cause devastating agroeconomic losses. Chemical fungicides are used to control fungal diseases, although this is not an ecofriendly approach. A recent study by Liu et al. highlighted the use of mycoviral gene-incorporating phytopathogenic fungi as biocontrol agents for disease management. 相似文献

A better understanding of crop genomes reveals that structural variations (SVs) are crucial for genetic improvement. A graph-based pan-genome by Yan et al. uncovered 424 085 genomic SVs and provided novel insights into heat tolerance of pearl millet. We discuss how these SVs can fast-track pearl millet breeding under harsh environments. 相似文献

Plants perceive sounds, while responses to these sounds were already known. A breakthrough is the discovery by Khait et al. that stressed plants emit various informative ultrasonic sound signals, which can be categorized according to plant species, stress type, and stress severity. This discovery may change how plants are cultivated. 相似文献

Funkhouser-Jones et al. recently identified gut metabolites that affected Cryptosporidium growth. A key focus, indole, was shown to inhibit the parasite in vivo and in vitro by decreasing the host mitochondria function and the membrane potential of parasite mitosomes. These findings help clarify the role microflora and metabolites play in host resistance. 相似文献

Phytochromes have a crucial role in the regulation of flowering in many plants, but the underlying molecular mechanisms vary among species. Recently, Lin et al. described a unique phytochrome A (phyA)-controlled photoperiodic flowering pathway in soybean (Glycine max), revealing a novel mechanism for photoperiodic regulation of flowering. 相似文献

A recent study (Johansen et al., 2023) shows how the ecological composition of the human gut virome changes with age, showing a decline in core taxa and an enrichment of subdominant taxa, similar to what has been observed in the gut bacteriomes of centenarians. 相似文献

Understanding a remarkable event at the start of life, the oocyte-to-embryo transition (OET), has remained elusive, especially in humans. Using newly developed techniques, Liu et al. showed that human maternal mRNAs undergo global poly(A) tail-mediated remodeling during OET, identified the enzymes involved, and demonstrated the essentiality of remodeling for embryo cleavage. 相似文献

Legumes coordinate nodulation and plant development to maximize reproductive success, but the underlying molecular mechanisms are not well understood. A recent study by Yun et al. has revealed that nodulation drives root-to-shoot movement of microRNA172 (miR172) to accelerate flowering time, thus building a new bridge between nodulation and plant growth regulation. 相似文献

Phytochemical study of Valeriana jatamansi Jones afforded 45 compounds, including twenty-three iridoids (1–23), five sesquiterpenes (24–28), three steroids (29–31) and fourteen lignins (32–45). The structures of these compounds were assigned by detailed interpretation of spectroscopic data (1D and 2D NMR, HRESIMS) and comparisons with the published data. This is the first report of isolation of compounds (1–6, 10, 21, 25, 41, 43, 44, 45) from Valerianaceae, compounds (13, 27, 39) within the genus Valeriana and compound 30 from V. jatamans. The chemotaxonomic data can support the genus Valeriana being accepted as a member of transitional taxa between the family Valerianaceae and Caprifoliaceae. 相似文献

David Rudner and his team (Gao et al.) predict a pentameric structure for the GerA alanine-responsive germination receptor of Bacillus subtilis and demonstrate that it behaves as a nutrient-gated ion channel, finally establishing a function for this novel family of receptors and focussing research on early ion movements in germination. 相似文献
