Thank You
Peach blossoms are highly
prized in Chinese culture
 More vitality than any other tree
 Peach rods to protect them from
evils
 Identifiable by their bright pink
flowers increase pollination

Anthocyanins are a group
of reddish-blue, watersoluble pigments common
in many flowers, fruits and
vegetables.
Possible health attributes,
such as reduction of
coronary heart diseases,
antioxidant properties, and
anti-cancer activities.
Bright coloration essential
to pollination.

in flowers.

 Varying factors effect the concentration of anthocyanins:
pH, light exposure, temperature and oxygen.


Dual color flower mutant and the control were
related to the changes of genetic material, some of
them may be related to the genes involved in
flower color formation.

Color,
In acidic soils, aluminum more available- binds to anthocyanin
pigments producing blues
 In alkaline soils, erratic aluminum uptake so pigments are pink.



To determine whether there is a difference in
anthocyanin pathway genes expression that
distinguish red color from white color in peach
flowers.
Focused on six genes: ANS, CHS, CHI, DFR,

• Objective: To extract total RNA
from the Hydrangea using the
RNA CTAB Protocol.
• Sample Collection: Collected
hydrangea flowers ; transfer to 80°C until RNA extraction. Petals
were ground in liquid nitrogen
in preparation for extraction.

0.5 g of Material add to 5ml CTAB extraction buffer water bath, plus 2% 2 mercaptoethanol, heated two 65 ° C placed in 10ml centrifuge tubes; then
incubated at 65 ° water bath 15min. Centrifuged at room
temperature 12000rpm 10min.
The supernatant is conserved and treated twice, with chloroform: isoamyl
alcohol (24:1) solution . Centrifuged at room temperature 12000rpm 10min.
Add 1/4 volume of 10M LiCl; 4 ° overnight- next day, 4 °
12000rpm centrifuge 20min
Discard supernatant, add 500ul SSTE dissolved about 10
minutes, transferred to 1.5ml tubes
Add an equal volume of chloroform: isoamyl alcohol, vortex, mix, 4 °
12000rpm centrifuge 10min; conserve the supernatant
Adding twice the volume of ethanol in the supernatant, placed in -70 °,
30min to 2 hours
4 ° C, 12000rpm centrifuge 15-20min, the supernatant drained, dried at room
temperature10min, adding appropriate amount of DEPC
water (60ul) dissolved RNA, spare.
