Training More Key Members of Plant Engineering for Industrial Enterprises

The plant is the material base of modern industry.In order to improve the performance of plants and the quality of products,it is very important that more key members shuld be educated and trained for mastering the maintenance and management of modern equipment.Since the founding of the China Research and Education Center of Plant Engineering(CRECPE)in 1984,the short-time training class has run 102 times,and more than 6 000 people trained during the past twelve years.This paper introduces modern industrial training based at CRECPE:its experiences, its training programs and methods,its new problems,and developments in the future.

Experimental Study on Key Techniques for Indoor Cultivation of Sprout Vegetables in Families

This paper introduced the advantages of planting sprout vegetables in family rooms,expounded assembly principle of indoor cultivating device and the key techniques for indoor cultivating sprout vegetables in families.In the experiment,we assembled a set of indoor cultivating device for sprout vegetables,and summarized the indoor cultivating techniques of sprout vegetables in families.The indoor planting device was suitable for family members to cultivate sprout vegetables in the living rooms,kitchen,balcony and other corner space by using their spare time.It could not only provide high-quality vegetables for families,but also beautify the indoor environments of family rooms,and increase the oxygen content in rooms.This set of indoor cultivating device and techniques was suitable for planting various sprout vegetables(e.g.radish seedling,water spinach seedling,pea seedling,pine willow seedling,sunflower seedling and various bean seedlings,etc.).This is a set of high-efficient spatial planting technique in families,and also an effective way to increase organic vegetable supply for family.

Orchid conservation in China from 2000 to 2020:Achievements and perspectives

We review achievements in the conservation of orchid diversity in China over the last 21 years.We provide updated information on orchid biodiversity and suggestions for orchid conservation in China.We outline national policies of biodiversity conservation,especially of orchid conservation,which provide general guidelines for orchid conservation in China.There are now approximately 1708 known species of Orchidaceae in 181 genera in China,including five new genera and 365 new species described over the last 21 years.The assessment of risk of extinction of all 1502 known native orchid species in China in 2013 indicated that 653 species were identified as threatened,132 species were treated as data-deficient,and four species endemic to China were classified as extinct.Approximately 1100 species(ca.65%)are protected in national nature reserves,and another~66 species in provincial nature reserves.About 800 native orchid species have living collections in major botanical gardens.The pollination biology of 74 native orchid species and the genetic diversity and spatial genetic structure of 29 orchid species have been investigated at a local scale and/or across species distributions.The mycorrhizal fungal community composition has been investigated in many genera,such as Bletilla,Coelogyne,Cymbidium,Cypripedium,and Dendrobium.Approximately 292 species will be included in the list of national key protected wild plants this year.Two major tasks for near future include in situ conservation and monitoring population dynamics of endangered species.

Phosphatidic acid plays key roles regulating plant development and stress responses

Phospholipids, including phosphatidic acid （PA）, phosphatidylcholine （PC）, phosphatidylethanolamine （PE）, phosphatidylglycerol （PC）, phosphatidylserine （PS） and phosphoinositides, have emerged as an important class of cellular messenger molecules in various cellular and physiological processes, of which PA attracts much attention of researchers. In addition to its effect on stimulating vesicle trafficking, many studies have demonstrated that PA plays a crucial role in various signaling pathways by binding target proteins and regulating their activity and subcellular localization. Here, we summarize the functional mechanisms and target proteins underlying PA-mediated regulation of cellular signaling, development, hormonal responses, and stress responses in plants.

Pilot plants of membrane technology in industry:Challenges and key learnings

Membrane technology holds great potential in gas separation applications,especially carbon dioxide capture from industrial processes.To achieve this potential,the outputs from global research endeavours into membrane technologies must be trialled in industrial processes,which requires membrane-based pilot plants.These pilot plants are critical to the commercialization of membrane technology,be it as gas separation membranes or membrane gas-solvent contactors,as failure at the pilot plant level may delay the development of the technology for decades.Here,the author reports on his experience of operating membrane-based pilot plants for gas separation and contactor configurations as part of three industrial carbon capture initiatives:the Mulgrave project,H3 project and Vales Point project.Specifically,the challenges of developing and operating membrane pilot plants are presented,as well as the key learnings on how to successfully manage membrane pilot plants to achieve desired performance outcomes.The purpose is to assist membrane technologists in the carbon capture field to achieve successful outcomes for their technology innovations.

Origin and evolution of green plants in the light of key evolutionary events

Green plants(Viridiplantae)are ancient photosynthetic organisms that thrive both in aquatic and terrestrial ecosystems,greatly contributing to the changes in global climates and ecosystems.Significant progress has been made toward understanding the origin and evolution of green plants,and plant biologists have arrived at the consensus that green plants first originated in marine deep-water environments and later colonized fresh water and dry land.The origin of green plants,colonization of land by plants and rapid radiation of angiosperms are three key evolutionary events during the long history of green plants.However,the comprehensive understanding of evolutionary features and molecular innovations that enabled green plants to adapt to complex and changeable environments are still limited.Here,we review current knowledge of phylogenetic relationships and divergence times of green plants,and discuss key morphological innovations and distinct drivers in the evolution of green plants.Ultimately,we highlight fundamental questions to advance our understanding of the phenotypic novelty,environmental adaptation,and domestication of green plants.

The lanternfly genus Pyrops Spinola(Hemiptera:Fulgoridae) from China with description of a new species

Species in the genus Pyrops Spinola (Hemiptera:Fulgoridae)in Chinese fauna are studied,one new species,P.jianfenglingensis sp.nov.is described from Hainan (southern China).Morphological characters and male genitalia of most Pyrops species in China are illustrated.A key for identifying the species of Pyrops from China is also provided.
