Monitoring hourly night-time light by an unmanned aerial vehicle and its implications to satellite remote sensing
Night-time light Unmanned aerial vehicle Hourly dynamic Urban function Spectral analysis
2023/12/21
Satellite-observed night-time light in urban areas has been widely used as an indicator for socioeconomic development and light pollution. Up to present, the diurnal dynamics of city light during the ...
Correlation of Leaf and Root Traits of Two Angiosperm Tree Species in Northeast China under Contrasting Light and Nitrogen Availabilities
leaf-specific traits leaf morphology root morphology leaf mass per area leaf density specific root length specific root area root tissue density
2023/12/19
Thinning is an important management practice for reducing plant competition and improving wood production in forests. The residues from thinning can contain large amounts of carbon (C) and nitrogen (N...

Silver fir is one of the longest living and tallest trees in Europe, it has major commercial importance and may be found in various communities predominantly connected with lower mountainous locations...
A microbiota–root–shoot circuit favours Arabidopsis growth over defence under suboptimal light
Arabidopsis suboptimal light MYC2 root–shoot signalling
2023/12/4
Bidirectional root–shoot signalling is probably key in orchestrating stress responses and ensuring plant survival. Here, we show that Arabidopsis thaliana responses to microbial root commensals and li...
Single-cell transcriptomics sheds light on the identity and metabolism of developing leaf cells
Single-cell transcriptomics photosynthetic Arabidopsis thaliana high-throughput transcriptome metabolic stress-related
2023/11/30
As the main photosynthetic instruments of vascular plants, leaves are crucial and complex plant organs. A strict organization of leaf mesophyll and epidermal cell layers orchestrates photosynthesis an...
γ-Aminobutyric acid plays a key role in plant acclimation to a combination of high light and heat stress
c-Aminobutyric acid high light heat stress Arabidopsis thaliana abiotic stresses metabolic response GABA
2023/11/30
Plants are frequently subjected to different combinations of abiotic stresses, such as high light (HL) intensity, and elevated temperatures. These environmental conditions pose a threat to agriculture...
The genome of homosporous maidenhair fern sheds light on the euphyllophyte evolution and defences
Adiantum capillus-veneris evolution of seed plants origin of euphyllophytes defences
2023/11/16
Euphyllophytes encompass almost all extant plants, including two sister clades, ferns and seed plants. Decoding genomes of ferns is the key to deep insight into the origin of euphyllophytes and the ev...
The asparagus genome sheds light on the origin and evolution of a young Y chromosome
雄性双倍体 芦笋 石刁柏 基因组测序
2023/3/31
该成果为江西省农业科学院牵头，与美国乔治亚大学和华大基因等联合，对雄性双倍体（YY）芦笋（石刁柏）进行全基因组测序，利用Illumina（二代）+PacBio（三代）+BioNano（基因组拼接系统）等多种技术手段组装，得到芦笋（石刁柏）基因组大小约为1.3Gb，有27,656个蛋白编码基因被预测。通过对石刁柏参考基因组的比较组学及实验分析发现，单独但相互关联的基因负责性别决定。性染色体在细胞遗传...
近日，北京航空航天大学的研究人员提出了一种新的漫射光学成像方法，利用结构光对吸收和散射效应进行解耦合，使用同时具有数百万调控单元和数十微秒调控速度的数字微镜阵列作为结构光调控器件，通过半色调（halftone）编码方法和散射介质的低通特性，打破了数字微镜阵列连续调（continuous-tone）编码造成的调控速度瓶颈，相比state-of-the-art，将成像速度提高了近100倍。该方法可以对...
