Following a season of diligent cultivation, the rice plants are ready for harvest. However, some rice plants have not headed yet and so are left unharvested in the fields. This delay is caused by infection with rice stripe mosaic virus, a newly emerged rice virus in southern China. Chen et al. (pages 2000-2016) demonstrated that the virus-encoded protein P6 hijacks the rice heading-related E3 ubiquitin ligase HAF1, leading to delayed heading. The infected plants that are left unharvested offer a conducive environment for the virus and its carrier, the leafhopper Recilia dorsalis, to overwinter.

In vivo haploid induction in cauliflower, kale, and broccoli

Modifying the centromeric histone CENH3 or PHOSPHOLIPASE D genes in cauliflower (Brassica oleracea var. botrytis) created haploid induction lines, which can be widely used for in vivo haploid induction in cauliflower, kale, and broccoli, thus enabling rapid utilization of germplasm resources and improving breeding efficiency.

D53 represses rice blast resistance by directly targeting phenylalanine ammonia lyases

In rice, DWARF 53 directly binds to the promoters of seven phenylalanine ammonia lyase genes, OsPAL1˜OsPAL7, and represses their expression, leading to decreased lignin accumulation and compromised resistance against Magnaporthe oryzae.

Green light mediates atypical photomorphogenesis by dual modulation of Arabidopsis phytochromes B and A

Green light regulates atypical photomorphogenesis in Arabidopsis thaliana via the dual regulations of phytochromes B and A. Although green light activates phyB and phyA, green light retards protein body formation of phyB in the nucleus and decreases the protein levels of phyA.

BBX9 forms feedback loops with PIFs and BBX21 to promote photomorphogenic development

The red-light photoreceptor phytochrome B interacts with and stabilizes the B-box protein BBX9 in the light. BBX9 forms a negative feedback loop with PHYTOCHROME-INTERACTING FACTORS (PIFs) and a positive feedback loop with BBX21, ultimately suppressing PIF activity and enhancing BBX21 activity, thus promoting photomorphogenesis.
