BrCYP71 mutation resulted in stay-green in pak choi (Brassica rapa L. ssp. chinensis).

BrCYP71 encoding multifunctional oxidase was mapped using BSA-Seq and linkage analysis, and its function in stay-green of pak choi was verified through Arabidopsis heterologous transgenic experiment. Stay-green refers to the phenomenon that plant leaves remain green during senescence and even after death, which is of great significance for improving the commerciality of leafy vegetables during storage or transportation and extending their shelf life. In this study, we identified a stay-green mutant of pak choi and named it nye2.

Background: Keloid is a benign skin tumor that result from abnormal wound healing and excessive collagen deposition. The pathogenesis is believed to be linked to genetic predisposition and immune imbalance, although the precise mechanisms remain poorly understood. Current therapeutic approaches may not consistently yield satisfactory outcomes and are often accompanied by potential side effects and risks.

Gene therapy is a rapidly developing field, finally yielding clinical benefits. Genetic engineering of organs for transplantation may soon be an option, thanks to convergence with another breakthrough technology, ex vivo machine perfusion (EVMP). EVMP allows access to the functioning organ for genetic manipulation prior to transplant.

Department of Biology and Molecular Sciences Research Center, University of Puerto Rico, San Juan, Puerto Rico.
Novel traits in the order Lepidoptera include prolegs in the abdomen of larvae, scales, and eyespot and band color patterns in the wings of adults. We review recent work that investigates the developmental origin and diversification of these four traits from a gene-regulatory network (GRN) perspective. While prolegs and eyespots appear to derive from distinct ancestral GRNs co-opted to novel body regions, scales derive from in situ modifications of a sensory bristle GRN.
