Post-transcriptional gene silencing 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, to counter host defenses.
The ubiquitin/proteasome pathway is a major system for the selective degradation of proteins in eukaryotes.
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.
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).
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 Waterfowl Virus Innovation Team from Shanghai Veterinary Research institute found that Newcastle disease virus induces stable formation of bona fide stress granules to facilitate viral replication through manipulating host protein translation.
Gene-targeting technologies using sequence specific nucleases have been widely adopted to induce genetic modifications in plant genome, of which generating targeted point mutation for gain-of-function phenotype is of great value.
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 at the 5’ end of target sequences (generally, 5’-TTTN).
The phenomenon is that when aphids attacked by parasitoids or predators, it alerts nearby conspecifics to escape by walking away and dropping off the host plant.
An important research progress which described genome-wide association study of 12 agronomic traits in peach was achieved by one team headed by Wang Lirong at the Zhengzhou Fruit Research Institute and published in Nature Communications in November, 2016.
