2021-10-25Arabidopsis OXIDATIVE STRESS 3 is able to enhance stress tolerance in fission yeast by promoting histone H2A variant replacementCaused by temperature , drought , salinity and heavy metals .Student LAI Dingwang and colleagues used a fission yeast ( S . pombe ) model system , which has been long served for studying oxidative stress responses , to probe.‘ AtOXS3 - mediated stress tolerance ’ was proposed ( Figure.1 ) . ？ Under abiotic stress , the histone H2A α.Enhances... Histone replacement during chromatin-remodeling plays a key role in transcriptional regulation. Replacing their canonical counterparts by histone variants often leads to gene expression changes in eukaryotes, which is one of the most important biological responses to stresses caused by temperature, drought, salinity and heavy metals.Read More

2021-10-25New progress on linked selection shapes the landscape of genomic variationDivergence between species is a fundamental question in evolutionary biology .Fig . 1 Genome-wide differentiation among the three oak species .Read More
How evolutionary forces shape patterns of genetic diversity within species and divergence between species is a fundamental question in evolutionary biology. The neutral theory of molecular evolution states that most polymorphisms within species are generally neutral and under mutation-drift equilibrium, and divergence between species is due... -
2021-09-22Recent progress in soil organic matter mineralization under nitrogen and phosphorus addition in Xiaoliang Research StationStudies have explored SOM mineralization using long-term fertilized soil .Long-term fertilization will change the soil biochemical properties , therefore , the changes of SOM mineralization under short-term or single nutrient input.More than bacterial abundance , especially in the soil with cellulose addition , and long-term fertilization had a ... Soil organic carbon (SOC) turnover is strongly influenced by substrate and nutrient availability, especially nitrogen (N) and phosphorus (P). Although many short-term N and P addition experiments have investigated the relationship between nutrient availability and soil organic matter (SOM) mineralization, few studies have explored SOM mineraliza...Read More -
2021-09-18South China Botanical Garden Xiaoliang Station Made Important Research Progress in the Research Direction of the Carbon Sequestration Function of Coastal Shelter ForestsImpact of fertilization on ecological functions of these coastal shelterbelts , especially the C sink function , is an essential scientific issue in the current.Coastal C sink research .Typical C . equisetifolia Coastal Shelter Forest of in Southern China ？ ( Photographed near the Experimental Platform of Coastal Shelter Forest , Xiaoliang Trop... Casuarina equisetifolia plantations have been widely established along tropical and subtropical coasts, where they act as a windbreak to shelter coastal areas. C. equisetifolia shelter plantations also fulfill another critical ecosystem service by sequestering large amounts of carbon (C), contributing to climate change mitigation. However, shelt...Read More -
2021-09-16Response of foliar nutrients to nitrogen and phosphorus addition in South ChinaAlthough only needed in small quantities , mineral nutrients like calcium , magnesium , zinc , copper , iron and manganese are important for plants .However , plants absorb these nutrients only from soils , and their availability may be.Fertilization control plots , + N , + P and + NP plots ) .Further affected their concentrations in plants , es... Although only needed in small quantities, mineral nutrients like calcium, magnesium, zinc, copper, iron and manganese are important for plants. However, plants absorb these nutrients only from soils, and their availability may be greatly affected by soil nitrogen (N) and phosphorus (P) availability. Here we used a forest fertilization experiment...Read More -
2021-09-15New progress on mapping China forest aboveground biomass through integration of multiple datasetsMapping spatial variation of forest aboveground biomass ( AGB ) at national or regional scale is important for estimating carbon emissions and removals and contributing to global stocktake and balancing the carbon budget .According to the 9th national forest inventory results , the forest area of China reaches 220.45 million hectares , with the ...Read More
Mapping spatial variation of forest aboveground biomass (AGB) at national or regional scale is important for estimating carbon emissions and removals and contributing to global stocktake and balancing the carbon budget. With the implementation of national ecological restoration projects, the forest area in China increased rapidly since the ... -

Botanic Gardens Conservation International (BGCI) has published a landmark State of the World’s Trees report on 1st September 2021. The report, compiling work led by the Global Tree Assessment (GTA), is the culmination of five years of research to identify major gaps in tree conservation efforts. It is one of the first assessments of the world...Read More -
