Knockout of impairs -mediated resistance against brown planthopper in rice.

The gene, known for its ability to confer resistance to the brown planthopper (BPH; Stål), has been extensively employed in rice breeding. However, the molecular mechanism by which provides resistance against BPH in rice remains poorly understood. In this study, we reported that the transcription factor was highly responsive to BPH infestation and exhibited early-induced expression in -NIL (near-isogenic line) plants, and OsWRKY71 was localized in the nucleus of rice protoplasts.

Identification and analysis of brown planthopper-responsive microRNAs in resistant and susceptible rice plants.

The brown planthopper (BPH) is the most devastating insect pest of rice. The rice gene BPH15 confers resistance to BPH. MicroRNAs (miRNAs) regulate a spectrum of development and defense response processes in plants.

BAC and RNA sequencing reveal the brown planthopper resistance gene BPH15 in a recombination cold spot that mediates a unique defense mechanism.

Background: Brown planthopper (BPH, Nilaparvata lugens Stål), is the most destructive phloem-feeding insect pest of rice (Oryza sativa). The BPH-resistance gene BPH15 has been proved to be effective in controlling the pest and widely applied in rice breeding programs. Nevertheless, molecular mechanism of the resistance remain unclear.

Knockdown of GDCH gene reveals reactive oxygen species-induced leaf senescence in rice.

Glycine decarboxylase complex (GDC) is a multi-protein complex, comprising P-, H-, T- and L-protein subunits, which plays a major role in photorespiration in plants. While structural analysis has demonstrated that the H subunit of GDC (GDCH) plays a pivotal role in GDC, research on the role of GDCH in biological processes in plants is seldom reported. Here, the function of GDCH, stresses resulting from GDCH-knockdown and the interactions of these stresses with other cellular processes were studied in rice plants.
