2026-11-06Systematically Reviews Functional Packaging Strategies: From Physiological Regulation to Intelligent MonitoringPostharvest fruits are highly susceptible to rapid senescence and microbial decay, a process primarily driven by intense respiration and endogenous ethylene signaling. While conventional packaging provides basic physical protection, the shift towards multi-component functional interfaces offers dynamic solutions for physiological regulation. Thi... Freshly harvested fruits remain as metabolically active living organisms with vigorous respiration and high ethylene sensitivity, and are therefore highly prone to softening, browning, water loss, and decay. At present, about 25% of the fruits are still lost in the post-harvest supply chain because of improper preservation, transport, or storage...Read More -
2026-11-06Breakthrough in Alfalfa Breeding at South China Botanical Garden: AtFLZ13 Enhances High Yield and Heat-Humidity Tolerance in Alfalfa to Advance the “North‑to‑South Forage Transfer” StrategyOverexpression of AtFLZ13 in alfalfa (cv. Zhongmu No. 1) enhanced biomass and heat-humidity tolerance in transgenic lines. This strategy holds promise for developing new cultivars suited to southern Chinese climates, thus expanding alfalfa’s cultivation range in China. Alfalfa (Medicago sativa L.) is the world’s most widely planted high‑quality perennial leguminous forage, delivering remarkable economic and ecological benefits. In China, alfalfa is predominantly grown in arid and semi‑arid northern regions. In southern China, however, hot summers coupled with frequent heavy rainfall severely hamper the grow...Read More -
2026-11-06VAMP Proteins Facilitate Cellulose Synthase for Secondary Cell Wall Build-upPlant cell walls, which underpin morphogenesis, growth, and development, depend on cellulose synthesized by plasma membrane–localized cellulose synthase (CESA) complexes. Here, we show that the SNARE proteins VAMP726 and VAMP725 associate with multiple CESAs, are co-delivered with them to the plasma membrane, and are important for CESA traffick... Plant cell walls, which are essential for growth and biomechanics, depend on cellulose synthesized by cellulose synthase (CESA) complexes localized at the plasma membrane. These CESAs are delivered to the cell surface via vesicles, a process that requires coordinated protein machinery. Vesicle membrane fusion is primarily mediated by soluble N-e...Read More -

2026-10-27Side Event on National Botanical Garden System and Biodiversity Conservation Successfully Held at the COP17 China PavilionThe side event at the COP17 China Pavilion, hosted by the South China Botanical Garden, gathered global botanical garden representatives to share progress on plant conservation mechanisms and China’s national botanical garden system. Participants jointly launched the International Initiative for Collaborative Botanical Garden Network and Biodiv... The Seventeenth meeting of the Conference of the Parties to the Convention on Biological Diversity (CBD COP17) is being held in Yerevan, Armenia, from 17 to 30 October 2026. On 20 October, the side event “National Botanical Garden System and Biodiversity Conservation” was organized at the COP17 China Pavilion. The event was hosted by South Chi...Read More -
2026-10-22Novel Mechanism by Which DNA Viruses Hijack Host Deubiquitinases UBP12/13 to Promote Viral InfectionPlant DNA viruses counteract host epigenetic silencing by hijacking the deubiquitinases UBP12/13 through their pathogenicity factors P6 (CaMV) and AC2 (CaLCuV), which directly bind UBP12/13 in the nucleus. UBP12/13 subsequently deubiquitinate H2A and reduce H3K27me3 modifications at the viral 35S promoter, relieving transcriptional repression of... Plant DNA viruses, including double-stranded DNA viruses (e.g., caulimoviruses) and single-stranded DNA viruses (e.g., geminiviruses), are devastating crop pathogens. Upon infection, viral genomes are packaged with host histones to form minichromosomes. Histone post-translational modifications (PTMs) play critical roles in viral replication and ...Read More -

2026-10-10Air-Layering Propagation of the Nationally Protected Plant Ormosia purpureiflora SucceedsAn important success has been achieved in the propagation of the nationally protected plant Ormosia purpureiflora using air-layering technology. This species is endemic to China, and only approximately 2,000 individuals have been found in Guangdong Province, where it has suffered from low seed set rates, as well as low seed germination and growt... Researchers from the Management Office of Guangdong Luofushan Provincial Nature Reserve, South China Botanical Garden (SCBG), the Chinese Academy of Sciences and Guangzhou Linfang Ecological Technology Co., Ltd., have achieved an important success in propagating the nationally protected plant Ormosia purpureiflora by air-layering technology.The ...Read More
