绿色条款进入《民法典》后经历了引入、冲突、协调三个阶段,目前正处于冲突与协调的过程中。为促进绿色条款的具体落实,应在《民法典》视角下对绿色条款进行系统分析。一方面,绿色条款契合民法传统的“权利-义务-保障”体系,体现为绿色物权、绿色义务和绿色侵权。另一方面,绿色条款与民法体系亦存在“公益-私益”冲突,体现为绿色物权的公私冲突,绿色义务的公益限制和绿色侵权的公私混同。为使绿色条款融入民法体系并适用,应从传统的公私冲突视角转变为公私协调视角,接纳绿色物权的公私融合,确定绿色义务的限制途径,进行绿色侵权的公私保障。

Polyvinyl chloride(PVc)has been shown to be degraded by some insect larvae;however,research is scarce on degrading bacteria. This study revealed that Zophobas atratus larvae were able to keep a higher survival rate only when taking in PVc and reached up to 72.33% within 30 d. Fourier transform infrared spectroscopy(FTIR)and thermogravimetric analysis(TGA)showed that the peak values of the major functional groups of PVc in the frass changed significantly,and the thermal stability decreased,indicating that PVc biodegraded in the gut of Z. atratus. Based on these,three PVc-degrading bacteria were isolated from the gut contents of the larvae with PVc as the only carbon source in the culture medium for selection,which were identified to be Enterococcus faecalis,Enterobacter hormaechei,and Bacillus subtilis. The degradation test of PVc showed that c5-1 had the greatest degradation efficiency among the three strains,which resulted in the weight loss of(6.19 ± 0.14)mg,and the water contact angle(WcA)decreased by 9.4° within 50 d effectively improving the hydrophilicity of PVc. In conclusion,the strain c5-1 isolated from the gut of Z. atratus larvae showed the high potential to be applied to the biodegradation of PVc plastics. © 2025 Science Press. All rights reserved.

Hematopoiesis is a finely tuned process that generates all blood cell types through self-renewal and differentiation, which is crucial for maintaining homeostasis. Acute infections can prompt a hematopoietic response known as emergency myelopoiesis. In this study, using a candida albicans (c. albicans) infection model, we demonstrated for the first time that disruption of Fhl2 led to increased fungal burden,heightened inflammatory response and reduced survival rates. Impaired myeloid hematopoiesis and immune cell production were evident, as proved by the decreased numbers of hematopoietic stem and progenitor cells (HSPcs) and granulocytes in the bone marrow of Fhl2-deficient mice. In conclusion, FHL2 regulated emergency myelopoiesis in response to c. albicans, affecting the host’s defense against pathogens.

To elucidate the process of adaptation, particularly the traits subject to natural selection and the molecular mechanisms underlying their natural variation, is one of the primary objectives of evolutionary biology. The uplifted landscape offers an excellent framework for understanding how organisms adapt to dramatic climatic gradients. To investigate the genetic basis of plant adaptation to the extremely high altitude, we first compared the genomic and phenotypic variations of two closely related Arabidopsis thaliana accessions from high altitude(Xizang, also known as “Tibet”) and low altitude(Yunnan), respectively. The Xizang population represents a relict group characterized by a small effective population size. Notably, the Xizang genome has more transposable elements(TEs) and more gene loss-offunction(LoF) mutations. Differentially expressed genes were enriched in biological processes of cellular response to oxygen-containing compound, regulation of defense response, and response to light intensity. Intriguingly, the phenotypic selection analysis revealed that silique density was under natural selection. Furthermore, we genetically mapped and validated that the LoF mutation of GA20ox1, the homologous gene of green revolution in rice, resulted in a higher silique density in Xizang Arabidopsis. Given that GA20ox1 is linked to Arabidopsis adaptation to the Alps Mountains, its parallel evolution plays an important role in the adaptation to Alpine habitats. Overall,our results highlight that identifying adaptive traits and elucidating the molecular mechanisms underlying natural variation of these traits is crucial for unraveling the mystery of adaptive evolution and has significant implications for crop breeding.
