  摘要：Reconciling the trade-off between short growth duration and high grain yield is essential for enhancing annual rice yields. We found that qTGW1a, encoding a flowering locus T-like protein, controls heading and nitrogen use efficiency (NUE) underpinning grain weight and yield in rice. TGW1a interacts with and stabilizes Ghd7 and Hd1 to boost NUE and grain yield. Natural variations in the promoter enable the ancestral allele TGW1aJZ to maintain an intermediate level of TGW1a transcription. By de...

  摘要：Could the global transition to renewable energy create a green dilemma that pits carbon reduction against biodiversity conservation? This study examined the effect of policies promoting solar photovoltaics on local avian biodiversity using a panel dataset covering 2344 counties in China from 2014 to 2023. Policies that favored photovoltaic expansion led to reductions in bird diversity, disproportionately affecting wealthier and nondesert regions, as well as widespread species. The mechanism op...

  摘要：Phages often degrade the genome of their bacterial host to individual nucleotides. In this work, we describe Metis, a bacterial defense system that directly senses phage-mediated host genome degradation. Metis aborts phage infection once it detects the modified mononucleotide N6-methyl-deoxyadenosine monophosphate (m6dAMP). As methylation of deoxyadenosines usually occurs on the DNA polymer, accumulation of m6dAMP signals that the host genome has been degraded. In type I Metis, sensing of m6dA...

  摘要：The grass family (Poaceae) has immense economic and ecological importance and exhibits distinctive metabolic traits, including dual starch and lignin biosynthetic pathways. We sequenced the genomes of Pharus, Joinvillea, Ecdeiocolea, and Typha species to investigate when and how these metabolic innovations evolved relative to the origin of the grass family. The rho whole-genome duplication (rho WGD) within the lineage that led to the last common ancestor of all grasses contributed to the gene ...
