Rational design of high-yield and superior-quality rice

April 7th, 2017

Rice (Oryza sativa L.) is a staple food for more than half of the world’s population. To meet the ever-increasing demand for food, because of population growth and improved living standards, world rice production needs to double by 2030. The development of new elite rice varieties with high yield and superior quality is challenging for traditional breeding approaches, and new strategies need to be developed.

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

February 9th, 2017

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,

Regulatory Role of OsMADS34 in the Determination of Glumes Fate, Grain Yield, and Quality in Rice

January 23rd, 2017

In most flowering plants, flowers consist of sepals, petals, stamens, and pistils, which are arranged in concentric whorls. Genetic and morphological studies of floral homeotic mutants in eudicots have established the classical ABC model of floral development, and subsequently the ABCDE model, which can also partly explain floral development in grass species.

Genome Editing in Rice Using CRISPR-Cpf1 System

December 14th, 2016

Cpf1 is a class 2/typeV CRISPR effector that has been recently harnessed for genome editing in animal and human cell. Compared with CRIPSR-Cas9 system, Cpf1 recognizes thymidine-rich sequence as the protospacer-adjacent motif (PAM) at the 5’ end of target sequences (generally, 5’-TTTN).

Fine mapping and candidate gene analysis of qHD5, a novel major QTL with pleiotropism for yield-related traits in rice (Oryza sativa L.)

November 2nd, 2016

Heading date (or flowering time, HD) represents one of the fundamental developmental events in the life cycle of the rice plant. It is one of the most important traits that enable rice to adapt to seasonal differences and specific growth conditions in diverse growing regions.
