SHVRI Researchers Indentify miR-130b as a Novel PRRSV Suppressor in Vitro and in Vivo

Recently, the lab of swine reproductive infectious diseases led by Dr. Tong Guangzhi at the Shanghai Veterinary Research Institute (SHVRI) of Chinese Academy of Agricultural Sciences (CAAS) identified miR-130b as a novel Porcine reproductive and respiratory syndrome virus (PRRSV) suppressor in vitro and in vivo. This finding has been published in the Scientific Reports on Nov. 19 2015 available here: http://www.nature.com/articles/srep17010 .
PRRSV is one the most economically important viral pathogens in pigs. The significant economic losses to the swine industry have stimulated searches for new ways to control PRRSV transmission. Meanwhile, microRNAs can impact viral infections by binding to sequences on viral RNA transcripts, usually resulting in the repression of virus replication. The researchers found that the delivery of multiple miR-130 family mimics, especially miR-130b, resulted in inhibition of PRRSV replication in vitro. Intranasal inoculation of piglets with miR-130b exhibited antiviral activity in vivo and partially protected piglets from an otherwise lethal challenge with Highly Pathogenic PRRSV strain.Read more >>

Progress on Molecular Mechanism of Grain Yield in Rice

Recently, scientists from China National Rice Research Institute (CNRRI) of Chinese Academy of Agricultural Sciences (CAAS) reached new progress on genetic mechanism of grain yield in rice.
In the study, CNRRI scientists characterized an abnormal flower and dwarf1 (afd1) mutant and AFD1 encoded a DUF640 domain protein. The afd1 mutant exhibited variable characteristics including the dwarfism, long panicles, low seed setting, small grains, and slender and thick hulls. This work would facilitate understanding of the molecular mechanism of vegetative and reproductive development, and provide insight into the functions of AFD1 gene on improving grain yield.Read more >>

CAAS Researchers Reveal a TCP Transcription Factor Essential for Tendril Development in Cucumber

Rare variants are important to agriculture, and the rare traits such as non-shattering of rice and dwarfism of wheat are fixed and selected during domestication. Recently, the Innovation Research Team of Functional Genomics from the Institute of Vegetables and Flowers (IVF), Chinese Academy of Agricultural Sciences (CAAS) exploit a strategy of rare variation mapping to discover a TCP gene essential to tendril development in cucumber (Cucumissativus L.). The results have been published online in Molecular Plant on October 24, 2015.
Tendrils are specialized climbing tools of cucumber, however, the homologous nature of cucumber tendril is controversial dating back to the time of Charles Darwin. In modern greenhouse, tendrils of cultivation of cucumbers are dispensable, and the coiling of tendrils actually requires additional energy investment from the cucumber plants and more labor from farmers in practice. Cucumber without tendrils is becoming the new breeding objective for plant architecture of cucumber. Read more >>

The AC5 Protein Encoded by Mungbean Yellow Mosaic India Virus is a Pathogenicity Determinant that Suppresses RNA Silencing-based Antiviral Defenses

The molecular features of begomovirus genomes have been thoroughly characterized, with the functions of most genes being well understood. Although an increasing number of begomoviruses have been annotated to contain an AC5/C5 ORF, little is known regarding its function during virus infection. Recently, the scientist in the Institute of Plant Protection has made a great progress in research on the function of the AC5 protein. the related research results have been published in New Phytologist.
It is generally accepted that begomoviruses in the family Geminiviridae encode four proteins (from AC1/C1 to AC4/C4) using the complementary-sense DNA as template. Although AC5/C5 coding sequences are increasingly annotated in databases for many begomoviruses, the evolutionary relationships and functions of this putative protein in viral infection are obscure. In this study, the scientists in IPP-CAAS demonstrated several important functions of the AC5 protein of a bipartite begomovirus, Mungbean yellow mosaic India virus (MYMIV). Read more >>

Scientists Reveal VILLIN2 as a Master Builder in Rice

Cytoskeleton is an important system in supporting the specialized cell morphology of a given organ. The plant cytoskeleton, mainly composed of microtubules and microfilaments (MFs), plays a critical role in regulating nearly all cellular activities, such as intracellular transport of organelles and vesicles, mitotic and meiotic cell division, and cell growth. However, the role of MFs in directed organogenesis and its underlying mechanism remain largely elusive, especially in crop plants. Recently, the Innovation Team of Crop Functional Genomics from Institute of Crop Science (ICS) of Chinese Academy of Agricultural Sciences (CAAS) has made a progress in identifying genetic linkage between MFs, auxin and organ growth.
To investigate the molecular mechanisms governing the assembly of plant architecture in rice, a mutant, designated as villin2 (vln2), was isolated by the team. vln2 displays organ malformations, such as twisted roots and shoots. Microscopy analysis revealed that the twisted mutant phenotype is caused by asymmetrical cell expansion on the opposite sides of a given organ. Read more >>

Researchers Identify a Crucial Virulence Determinant of Infectious Laryngotracheitis Virus (ILTV)

The lab of avian respiratory infectious diseases led by Dr. Liu Shengwang at the Harbin Veterinary Research Institute (HVRI) of Chinese Academy of Agricultural Sciences (CAAS) identified the first host modulator of ILTV infection. This finding has been published in the Journal of Virology.
Infectious laryngotracheitis (ILT) is a major respiratory disease of chickens which could cause large economic losses to the poultry industry worldwide annually. Given the side effects of vaccination against ILT, novel strategies for ILT control and therapy are urgently needed. Using genome-wide transcriptome studies in combination with a bioinformatic analysis, Dr. Liu and his colleagues identified proto-oncogene tyrosine-protein kinase SRC (SRC) as an important modulator of ILTV infection. Their further studies revealed that SRC controls the virulence of ILTV through a positive feedback loop with the tyrosine kinase focal adhesion kinase (FAK). Read more >>
