The study of two Magnoliales species, Myristica fragrans and Cananga odorata, reveals insights into the genomic basis of holocentric transition. The research team assembled chromosome-level genomes and compared them using integrated multi-omics analyses, identifying structural and functional differences between the holocentric and mono...
Endosymbionts in insects drive cryptic speciation through ecological adaptation, gene transfer, and reproductive manipulation, leading to genetic differentiation and reproductive isolation
A team assembled the first gap-free telomere-to-telomere genome of Canavalia gladiata, combining with integrated transcriptomic and metabolomic profiling of developing seeds. The study reveals a metabolic switch during seed development, with a clear transition from starch and sucrose metabolism to fatty acid accumulation.
A recent study found that spiders from different lineages construct similar funnel-shaped webs, despite diverging hundreds of millions of years ago. Genomic analysis identified genes involved in neural regulation, sensory processing, and motor control, suggesting that complex behaviors can evolve repeatedly in distantly related lineages.
Marmots' evolutionary history traces back to North America, with dispersal events through Beringia shaping their modern distribution. Climate and mountain changes drove diversification, resulting in regional adaptation and allopatric speciation.
Macropis bees primarily visit nectar-bearing Lysimachia species, including L. stenosepala, to feed on nectar and patrol for mates. This specialization contradicts prior observations of their association with oil-secreting loosestrifes.
A new study documents 2,304 grass species in China, including 1,978 native and 326 alien species, with 52% of native species endemic to the region. The checklist highlights conservation efforts for threatened species, invasive aliens, and guides biodiversity research.
The Journal of Systematics and Evolution (JSE) is launching a special issue on deep sea biodiversity, covering taxonomy, phylogenomics, comparative genomics, and microbial ecology. Researchers worldwide can submit free-access papers with waived page and color charges until January 31, 2027.
A new review reveals how plant characteristics influence wetland ecosystem functioning and provides insights for conservation and restoration. Dominant plant traits support higher productivity and long-term soil carbon storage in wetlands.
Researchers from Guizhou Province have successfully assembled the first haplotype-resolved chromosome-level genome of Phoebe zhennan, a critically endangered tree species. The high-quality reference genome reveals significant genetic variations, including inversions and translocations, that may play key roles in environmental adaptation.
Research reveals that drought stress stimulates primary root elongation in plants, allowing them to adapt and survive. The plant hormone abscisic acid plays a crucial role in this process by integrating with other hormonal signals to promote primary root growth.
Keping Ma, a CAS academician, honors Peter H. Raven's contributions to coevolution, angiosperm biogeography, and plant conservation. Raven's work on butterflies and plants introduced the concept of reciprocal adaptation and ecological networks.
