Maintenance of a Living Understory Enhances Soil Carbon Sequestration in Subtropical Orchards

Agroforestry systems play a central role in the global carbon (C) cycle and contain approximately 12% of the Earth’s terrestrial C. Agroforestry is a management system that integrates trees with farms in an agricultural landscape and usually encompasses a wide variety of understory vegetation management methods. Many studies have shown that man...

Hydrogen (H2) was found to be involved in phytohormone signaling

There is a close relationship between gas and organisms. Besides the involvement of carbon dioxide (CO2) and oxygen (O2) in photosynthesis, other gases, such as hydrogen (H2), methane, ethylene, carbon monoxide (CO) and hydrogen sulfide (H2S) are proved to be involved in various biological activities. From an evolutionary perspective, the origin...

Studies Reveal Rice Genes for Iron-Sulfur Cluster assembly are Responsive to Abiotic Stress

Iron-sulfur proteins are a group of proteins containing iron-sulfur cluster (Fe-S cluster) as cofactors. These proteins play important roles in photosynthesis, respiration, and DNA repair. About 43 genes have been identified to be the Fe-S cluster assembly genes in Arabidopsis genome. As the most important crop in Asia, rice is vital for iron nu...

Pollen morphology and ultrastructure of selected species from Annonaceae

Pollen is one of the most valuable sources of evidence for phylogenetic analysis, clarifying higher-level relationships, and studies of origins of the family. The Annonaceae have the greatest diversity in basal angiosperms among and within genera, not only at the macromorphological level but also at the pollen morphological level. Dr. Fengxia Xu...
