Abstract Relatively poor in vitro rooting has limited the large-scale commercial production of tree peony. In this study, on the basis of transcriptome sequencing, differentially expressed genes and the associated metabolic pathways were identified in tree peony roots at different stages of root formation under sandy loam cultivation. A total of 31.63 Gb raw data were generated and 120,188 unigenes (mean length of 911.98 bp) were annotated according to six databases (NR, NT, GO, KEGG, COG, and Swiss-Prot). Analyses of the ungerminated root primordium period, induced root primordium period, and root formation period detected 8,232, 6,907, and 10,687… More >

Abstract This research uses the immature embryos of inbred maize lines (GSH9901, Hi01, Hi02, and Chang 7-2) as receptor materials to establish the callus induction system. These inbred lines provide the receptor materials for the genetic regeneration of maize and the verification of the genetic functions of maize. The factor experiment and orthogonal experiments were used to investigate the impacts of different genotypes, immature embryo size, shield orientation, 2, 4-D concentration, proline concentration, and folic acid concentration on the induction rate of embryogenic callus tissue. A sensitivity experiment testing glyphosate (Bar) and an antibiotic (Cefotaxime sodium)… More >
