2026-06-23New progress in the regulatory mechanism of aluminum tolerance in Rhodomyrtus tomentosa via cell wall remodelingAcidic soils account for approximately 40%-50% of the world's arable land, making them one of the major abiotic stress factors constraining agricultural production. In acidic soils, Al³⁺ inhibits root elongation and nutrient uptake, ultimately leading to significant crop yield losses. The plant cell wall serves as the first physical barrier ag...Read More -
2026-06-22SCBG proposes a whole-system method for tracing wetland organic carbon sourcesA full‑system method for tracing wetland organic carbon sources is established by determining n-alkane and amino sugar biomarkers in sediments and calculating contributions based on these dual biomarkers and total carbon content. The method resolves six carbon sources—herbaceous plants, algae, woody plants, aquatic plants, fungal necromass, an... South China Botanical Garden, Chinese Academy of Sciences has filed a patent application titled “A whole-system method for tracing organic carbon sources in wetlands.” The method addresses the complex origins of organic carbon in saltmarshes and other wetland ecosystems, where conventional tracing approaches often provide only broad source sep...Read More -

2026-05-22New Species of Glomeridae Discovered in Dinghushan, Guangdong, Filling a Zoogeographic Gap for Millipedes in ChinaThis study describes a new pill millipede species Rhopalomeris dinghushan sp. nov. from Dinghushan National Nature Reserve, Guangdong Province, using an integrative taxonomic approach combining morphology and COI gene barcoding, which represents the first record of the genus Rhopalomeris in China.This discovery fills the zoogeographic gap of the... On May 20, 2026, the international zoological taxonomy journal ZooKeys published online a research result by a team from the South China Botanical Garden (Chinese Academy of Sciences), South China Agricultural University, Sun Yat-sen University, and other institutions. During biodiversity surveys and monitoring in Dinghushan National Nature Rese...Read More -
2026-05-19Tropical Primary Forest Plants Up-regulate Root Exudation to Adapt to Long-term High Nitrogen DepositionIt remains unclear how tropical and subtropical forests adapt to nutrient imbalance under long-term elevated nitrogen deposition. This study reveals that trees accelerate rhizosphere phosphorus mobilization by increasing carbon allocation to root exudation, which challenges the conventional paradigm that long-term nitrogen deposition reduces bel... Intensifying global nitrogen (N) deposition has disrupted the N–phosphorus (P) balance in ecosystems, particularly in tropical and subtropical regions where available P is relatively scarce. Extensive studies in temperate N‑limited ecosystems have led to a classic paradigm: N addition alleviates plant competition for N, thereby reducing the al...Read More -
2026-05-13Multiple newly recorded species of wildlife and plants have been continuously discovered at Dinghushan National Nature ReserveBased on daily wildlife monitoring and field surveys, five new records of amphibians and reptiles and one new record of an orchid species were documented in the Dinghushan National Nature Reserve of Guangdong province . These new records enrich the species list of the Dinghushan Reserve, confirm the continuing improvement of the regional ecologi... Recently, the scientific monitoring team of Dinghushan National Nature Reserve in Guangdong, China, has recorded and confirmed five new amphibian and reptile species—Sphenomorphus tonkinensis, Pseudocalotes microlepis, Dibamus bourreti, Pareas formosensis, and Paramegophrys liui—along with Epipogium roseum, a rare orchid species. These finding...Read More -
2026-05-12【South】Exotic plant blooms again at South China National Botanical Garden after four yearsThe Amorphophallus paeoniifolius, a rare plant known for its short-lived bloom, has flowered again at the South China National Botanical Garden in Guangzhou. The Amorphophallus paeoniifolius, a rare plant known for its short-lived bloom, has flowered again at the South China National Botanical Garden in Guangzhou. This is the first time it has bloomed there in four years, drawing crowds of visitors to the garden's Rare and Exotic Plant Conservatory.As a member of the Araceae family, Amorphophallus pa...Read More
