The Rice AAA-ATPase OsFIGNL1 is Essential for Male Meiosis
Meiosis is crucial in reproduction of plants and ensuring genetic diversity. Meiosis is a critical step in gametogenesis, during which two rounds of cell division follow a single round of DNA replication, ending with formation of four haploid cells. Disturbing any step of this progress leads to severe dysfunction of meiotic cells, including aberrant chromosomes, abnormal pairing of homologs, reduction of chiasma frequency, and infertility. Although several genes involved in homologous recombination and DNA repair have been reported, their functions in rice (Oryza sativa) male meiosis remain poorly understood.
Recently, researchers at Key Laboratory for Zhejiang Super Rice Research and State Key Laboratory of Rice Biology, China National Rice Research Institute (CNRRI) of Chinese Academy of Agricultural Sciences (CAAS) have acquired progress on molecular mechanism of male sterility in rice. In this study, CNRRI scientists successfully identified a complete male sterility mutant Osfignl1. The rice Osfignl1 mutant exhibited normal vegetative growth, but failed to produce seeds and displayed pollen abortion phenotype. Read more >>

Nitrogen Metabolism in Adaptation of Photosynthesis to Water Stress in Rice Grown under Different Nitrogen Levels
Recently, a paper named Nitrogen Metabolism in Adaptation of Photosynthesis to Water Stress in Rice Grown under Different Nitrogen Levels reported by Jin Qianyu's research team from China National Rice Research Institute (CNRRI) of Chinese Academy of Agricultural Sciences (CAAS) was published on the Frontiers in Plant Sciences. The roles of N metabolism in the adaptation of photosynthesis to water stress in rice were investigated in this paper.
Photosynthesis is one of the physiological processes that is easily impacted by water stress. The majority of assimilated N in plants is also invested in photosynthetic machinery, but there is ongoing debate concerning the role of N metabolism in the adaptation of photosynthesis to water stress in rice.

“Two-florets Spikelet” As a Novel Resource has the Potential to Increase Rice Yield
Recently, the research on rice floret number was achieved by a research team led by Professor Qian Qian from China National Rice Research Institute of Chinese Academy of Agricultural Sciences (CAAS). The paper “Two-florets spikelet” as a novel resource has the potential to increase rice yield analyzed the regulation of floret number in rice, which laid a foundation for molecular breeding of rice high production.
The grain number per panicle (floret number) is an important factor of grain yield. Presently, it is difficult to increase the grain number by increasing the branch number or grain density in China, so it is necessary to find new ways to increase the grain number per panicle. In fact, another important factor (floret number in a single spikelet) which controlled the grain number per panicle was rarely focused because a normal rice spikelet has one fertile floret and produces one seed.

Echinochloa crus-galli Genome Analysis Provides Insight into Its Adaptation and Invasiveness as a Weed
A new research progress was achieved by research teams led by Professor Guo Longbiao from China National Rice Research Institute (CNRRI) of Chinese Academy of Agricultural Sciences (CAAS) and Professor Fan Longjiang from Zhejiang University. A new understanding of the molecular mechanisms underlying the extreme adaptation and invasiveness of the hexaploid species Echinochloa crus-galli (E. crus-galli), a pernicious weed in agricultural fields worldwide was acquired.
E. crus-galli is one of the most serious agricultural weeds in the world. Barnyardgrass (E. crus-galli) and rice belong to Gramineae, both have similar biological characteristics like rapid growth rates, plant type, prolonged dormance and others. That is the reason why it is very difficult to control the paddy fields associated with Barnyardgrass via manual weeding. Paddy weeding is currently largely dependent on chemical herbicides.

The scientific research teams of Institute of Environment and Sustainable Development in Agriculture (IEDA) and Biotechnology Research Institute of Chinese Academy of Agriculture Sciences (CAAS) have conducted the joint research and developed a new method for plant genetic transformation with high-throughput, convenient operation and wide purposes by using magnetic nanoparticles as gene carriers. Their study makes important progress in the research on the nano-carrier gene delivery and genetic mediated systems, developing a new direction of nano-biotechnology research. The relevant research results were published online in the authoritative academic journal Nature Plants on November 27th, 2017.
The development of a new efficient genetic transformation method has always been one of the hotspots in the fields of genetic engineering, molecular biology and genetic breeding. Read more >>
