This paper reviews a study that analyzes whether the QPT1 and QPT2 promoters are capable of carrying out their functions as promoters in different plant species. Furthermore, the paper looks at how this experiment explores the strength of the QPT2 promoter against the CaMV35S promoter, the effects of wounding and the effects of the treatments on different tissues like leaves and roots. The paper outlines and discusses the methods used and results gained, and concludes with a summary of the findings of the study.

Materials and Methods

From the Paper:

"Each of the four plants species N. tabacum, Daucus carota (carrot), Petunia parodii (petunia) and Capsicum annum (chilli) were transformed with four different Agrobacterium rhizogenes strains. One of these strains had the wild type with no promoter added, while each of the other three strains had a CaMV35S, NQPT1 or NQPT2 promoter added. These plant tissues were agro-infected with the Agrobacterium rhizogenes suspensions and then incubated at 25oC for three days, after which, the ex-plant discs were transferred into fresh agar dishes M+S nutrient media containing 500mg/L cefotaxime. Three days later a second transfer to M+S cx medium was done. Five weeks after initial infection, transgenic roots were observed and the number of roots for both ex-plant species was counted. Using forceps, 20 roots from each plant species were put into Petri dishes with 2mL X-Gluc staining buffer and incubated overnight at 37oC. After the roots were stained the buffer was replaced with 70% ethanol. The number of roots that stained blue out of the 20 roots examined in all species was recorded (Song et al., 2012)."
