2024-04-30How to link plant functional traits to biodiversity under environmental change?Further provide links with biodiversity at broader temporal and spatial scales .Science , Research field : Plant functional traits , adaptation and evolution , E-mail : hui . liu @ scbg . ac . cn .A diagram of the linkage between functional traits and biodiversity at multiple ecological scales .Read More
Understanding the mechanisms underpinning the origins, patterns and dynamics of biodiversity is fundamental in biology and ecology. Trait-based ecology emphasizes the importance of functional traits in community assembly and ecosystem properties, however, functional traits can further provide links with biodiversity at broader temporal and ... -

Ziwei Wang ( Current affiliation is School of Biology and Agriculture , Shaoguan University ) , and master student Gui Xiong of South China Botanical.Oat wild germplasm resources through breeding programs in Poaceae (...Read More
Oats have been domesticated more than 3,000 years ago while growing as a weed in wheat fields in the Anatolian region of Turkey. Their genomes are rich in genetic diversity, as shown by the large genome size (12.6 Gb, 6x) and the mosaic-like chromosomes. Little is known about the evolutionary events that lead to structural variation in oat ... -
2024-04-26Mechanisms of soil organic carbon accumulation in acidified forest soilsAccumulation in deeply acidified forest soil remains unclear .Science , Research field : Forest ecology and soil carbon cycle , E-mail : yumx @ scib . ac . cn ? .Read More
Southern forests contribute more than 50% of soil organic carbon (SOC) in China’s forest ecosystem, and the soil can still accumulate SOC. Deeply developed tropical and subtropical forest soil has undergone severe acidification. Based on the input-output principle, the accumulation of Al toxicity caused by Al3+ aggregation, results in a de... -
2024-04-24Vertical Dimension: A Complementary Perspective to Interpret Niche DifferentiationPosits that niche differentiation is a prerequisite for species coexistence .Influencing vertical stratification and habitat adaptation of tree species , verifying the vertical effects of ecological strategies ( published in Functional.The coexistence mechanisms of subtropical forest tree species .Relationship between diameter at breast height (...Read More
The classical ecological theory posits that niche differentiation is a prerequisite for species coexistence. Natural forests exhibit distinct stratification, where the horizontal and vertical structures collectively form the community structure. Horizontal ecological niche differentiation alone is insufficient to explain the coexistence of ... -
2024-04-24High Soil Phosphorus Content Reduce the Competitive Ability of the Invasive Plant Chromolaena odorata in Tropical Coral IslandsAlien plant invasion results in severe socioeconomic and environmental damage worldwide .However , the effects of soil phosphorus content and light intensity on the competitive advantage of C . odorata and the native species Pisonia grandis and Scaevola taccada in tropical coral islands is still not clear .? Figure . The relative growth rates (...Read More
Alien plant invasion results in severe socioeconomic and environmental damage worldwide. The negative effects of invasive plants on islands are worse than those on the mainland. Chromolaena. odorata is one of the most common invasive plant species in the world. It is currently one of the main invasive plant species in the Paracel Islands, a... -
2024-04-16A rapid and efficient method for plant genetic transformationCrops and development and utilization of plant resources .Compared to the traditional transformation methods , RAPID has a higher transformation efficiency ( increased by 20 ~ 100 times ) , shorter duration ( reduced by 2 ~ 3 times ) , and does not require tissue culture.Applied to a wide range of plant species that are capable of regeneration ....Read More
Plant genetic transformation is essential for crop engineering and modern molecular breeding. However, the existing transformation protocol is complex and inefficient, limiting genetic modification of most crops and development and utilization of plant resources.
To address this challenge, Guangzhou researchers have developed a novel pl... -

A comprehensive review of the meta-analysis was carried out by Prof . HOU Enqing ’ s team and published...Read More
The drive to increase crop production to meet the increasing food demand has led to excessive use of nitrogen fertilizers, but nitrogen use efficiency has not increased accordingly. Rather, excess nitrogen released into the environment has caused severe environmental pollution. To understand the status of knowledge-based nitrogen management...
