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

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

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

Productive invasion of hepatocytes by Plasmodium sporozoites is a key step of infection. The parasites traverse hepatocytes before targeting one of them to form a parasitophorous vacuole for parasite expansion. Schepis et al. show the induction of membrane ruffling via host Rho GTPases by Plasmodium sporozoites facilitating productive invasion. 相似文献

During hypocotyl development, an asymmetric auxin gradient causes differential cell elongation, leading to tissue bending and apical hook formation. Recently, Ma et al. identified a molecular pathway that links auxin with endoreplication and cell size through cell wall integrity sensing, cell wall remodeling, and regulation of cell wall stiffness. 相似文献

Strigolactones from the exudates of maize root induce germination of the parasitic witchweed Striga. Recently, Li et al. characterized the biosynthesis pathway of two strigolactones, zealactol and zealactonoic acid, which induce less Striga germination than the major maize strigolactone, zealactone. This study provides a promising strategy for plant protection against parasitic witchweed. 相似文献

Many molecular mechanisms underlying blood glucose homeostasis remain elusive. Juan-Mateu et al. find that pancreatic islet cells utilize a regulatory program, originally identified in neurons, that involves alternative splicing of microexons in genes important for insulin secretion or diabetes risk. 相似文献

Throughout evolution, only two known primary photosynthetic endosymbiosis occurred, which originated the Archaeplastida and the Paulinella spp. Fundamental questions regarding primary endosymbiosis remain unsolved, but may now be addressed with the recent development of chimeric photosynthetic life-form. Cournoyer et al. could establish artificial photosynthetic endosymbiosis between yeast and cyanobacteria. 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

It has been demonstrated that reactivation of endogenous retroviruses (ERVs), the remnants of ancient retroviral infection, participate in various physiological and pathological conditions. Liu et al. recently showed us very interesting findings that aberrant expression of ERVs, induced by epigenetic alterations, accelerates cellular senescence. 相似文献

Compensation and overcompensation under field conditions are confirmed in Aedes mosquitoes recently by Evans et al.: equal or increased densities of emerging adults may thus result from reduced larval densities. Here the consequences when applying the sterile insect technique and provide recommendations to avoid counterproductive effects are discussed. 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

Nature-designed plant microbiomes may offer solutions to improve crop production and ecosystem restoration in less than optimum environments. Through a full exploration of metagenomic data, Camargo et al. showed that a previously unknown microbial diversity enhances nutrient mobilization in stress-adapted plants. 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

Strangely, American black bears come in many colours. New work by Puckett et al. shows that a missense alteration in the gene encoding tyrosinase-related protein 1 (TYRP1) likely interferes with melanin synthesis and is responsible for the cinnamon colour variant in the southwest USA. However, the adaptive significance of colour polymorphisms in this large carnivore remains opaque. 相似文献

In plants, uridine diphosphate (UDP)-dependent glycosyltransferases (UGTs) catalyze glycosylation of secondary metabolites, but assigning physiological functions to UGTs is still a daunting task. The recent study of Wu et al. presents a useful method to resolve this problem by elegantly combining modification-specific metabolomics with isotope tracing. 相似文献
