The Rice Dynamin-related Protein OsDRP1E Negatively Regulates Programmed Cell Death by Controlling the Release of Cytochrome c from Mitochondria

To death or not, is controlled by the processes of PCD (programmed cell death) in animals and plants. PCD plays important roles in growth and development, as well as biotic or abiotic stresses. The lesion mimic mutation in plants, which leads to spontaneous formation of cell death in the absence of infection by exogenous pathogens, induces the expression of resistance-related genes and increases plant defense against insect pests and diseases. Understanding of the mechanism of plant PCD provides the molecular basis for developing new resistance materials in crop breeding. Recently, research groups from the State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection of CAAS have discovered a Dynamin related protein (DRP) which plays a negative role in the rice PCD, and they published their findings on the open accessed journal PLoS Pathogens.Read more >>

The Porcine Respiratory Syndrome Innovation Research Team of SHVRI Revealed a New Mechanism for the Inhibition of Antigen Presentation by Highly Pathogenic Porcine Reproductive and Respiratory Syndrome Virus (HP-PRRSV)

Recently, The Porcine Respiratory Syndrome Innovation Research Team, led by Prof. Zhiyong Ma, has revealed a new mechanism for the inhibition of antigen presentation by highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV). This study provides new insights for further understanding of the immunosuppression and immune escape mechanisms. Research results were published on Journal of Virology online.
Porcine reproductive and respiratory syndrome virus (PRRS) is one of the most important diseases which impair the global pig industry. PRRSV has a variety of strategies to evade and inhibit the immune clearance of the host.Read more >>

A Calmodulin-like Protein Suppresses RNA Silencing and Promotes Geminivirus Infection by Degrading SGS3 via the Autophagy Pathway in Nicotiana Benthamiana

Post-transcriptional gene silencing (PTGS) is an elaborately regulated process for defense against virus infection in plants. To achieve effective infection, a betasatellite molecule associated with geminivirus induced high levels of an endogenous RNA silencing suppressor, calmodulin-like protein (CaM), to counter host defenses. However, the mechanism underlying CaM-mediated PTGS suppression is poorly understood. Recently, researchers at the State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection of CAAS have published a research paper about autophagy pathway-mediated degradation of SGS3 by CaM in Nicotiana benthamiana.
They have previously demonstrated that CaM is an endogenous RNA silencing suppressor that suppresses PTGS and enhances geminivirus infection. The research showed that CaM from Nicotiana benthamiana (NbCaM) interacts with and degrades Suppressor of Gene Silencing 3 (NbSGS3). Read more >>

A Novel Mechanism on Newcastle Disease Virus Inducing Stable Formation of Bona Fide Stress Granules to Facilitate Viral Replication Found by SHVRI

Recently, the Waterfowl Virus Innovation Team from Shanghai Veterinary Research institute ( SHVRI )found that Newcastle disease virus (NDV) induces stable formation of bona fide stress granules (SG) to facilitate viral replication through manipulating host protein translation. The results were published online in FASEB Journal (Impact factor: 5.299).
NDV was considered as the important avian virus causing great damage in poultry industry. NDV selectively replicates in chicken and tumor cells, but not in normal cells. The study of NDV replication mechanism is of great significance to anti-NDV and anti-tumor therapy. Mammalian cells enter a relatively stable state by temporarily inhibiting cellular protein translation when exposed to various environmental stressors. Read more >>

OsCUL3a Negatively Regulates Cell Death and Immunity by Degrading OsNPR1 in Rice

The ubiquitin/proteasome pathway is a major system for the selective degradation of proteins in eukaryotes. Previous studies in plants have demonstrated that the ubiquitin/proteasome pathway is an essential component of the regulatory networks controlling many important cellular processes, including growth and development, as well as defense responses. Among the three major enzymes in this pathway, the E3 ubiquitin ligases are responsible for controlling the specificity of target protein recognition and degradation via the 26S proteasome. A prominent subset of the E3 ligases are the Cullin-RING E3 ligases (CRLs), in which the Cullin3 (CUL3)protein is known to function in the regulation of PCD in animals. In plants, the transcription coactivator NPR1 (NONEXPRESSOR OF PATHOGENESIS-RELATED GENES 1) is a master regulator of both basal and systemic acquired resistance (SAR). Read more >>

International Cooperation Update

Research on the Establishment and Application of High - efficiency and Low - risk Technology System for Pesticides won the 2nd award of National Prize for Progress in Science and Technology in 2016

National Prize for Progress in Science and Technology for achievements in 2016 was awarded in the Great Hall of People on 9 January, 2017. Chinese President XI Jinping and Premier Li Keqiang were present at the awarding conference and presented the awards to the representatives of the winners. Prof. ZHENG Yongquan, from the Institute of Plant Protection (IPP), as one of the winners, attended the conference. The achievement Establishment and Application of High - efficiency and Low - risk Technology System for Pesticides, presided by ZHENG, won the 2nd award of the prize.
It is said that pesticide is an indispensable mean of production to safeguard agro-products. However, the typical ecological toxicity and the unreasonable application of pesticides have brought about a lot of negative impacts. Read more >>

Mozambique's Parliament Speaker Visits CAAS

On February 14, Speaker of Mozambican Parliament Veronica Macamo visited CAAS, accompanied by Yang Jianting, Member of the Foreign Affairs Committee of the National People’s Congress (NPC). Prof. Chen Mengshan, Secretary of the Leading Party Group and Vice President Wu Kongming met with the delegation. The two sides conducted in-depth exchanges on strengthening agricultural cooperation within the framework of Johannesburg Summit of the Forum on China-Africa Cooperation.
Chen Mengshan first briefed the guests on China’s experience in agricultural development over the past three decades. He mentioned that China is a large agricultural country, while its arable land per capita only accounts for 43% of the world average level and the availability of water resources per capita is only a quarter of the world average. Chinese government has attached great importance to the development of agriculture, rural areas and farmers since the reform and opening up. Read more >>

CAAS President Tang Huajun Meets with Director General of IRRI

On March 14, Prof.Tang Huajun,President of Chinese Academy of Agricultural Sciences (CAAS) met with Dr. Matthew Morell, Director General of International Rice Research Institute (IRRI) and his delegation. The two sides exchanged views on further cooperation. Prof. Wu Kongming, Vice President of CAAS, attended the meeting.
