What is Star-Chlamy?
"Starchlamy can be understood as "A superstar in future
agriculture" and "Starch(Ch)lamy".
We modified these
Chlamydomonas reinhardtii strains to realize the potential to produce starch
efficiently in syhthetic plant without taking up much land.
Land-Consuming Food Production:
as we know it
Up to today, the most common agricultural paradigm is still highly dependent on land. According to FAO, over 95% of world crop production comes from land. The plough supports every
harvest with its nutration and fertileness.
However, at the same time, high dependency means the same threat will come to food production as to the arable land.
It
is necessary that we must be visionary enough to cultivate the possibility of
land-free agriculture to reduce the dependence.
The Global Arable Land Crisis
What's worse, due to natural hazards such as desertification, salinization, and soil erosion, a large amount of
arable land loses its productivity every year around the world, and that strengthen the necessity mentioned
above.
Although arable land is
constantly decreasing, the rate of global population growth is
accelerating, and the demand for
food is constantly rising. Against this backdrop, the food crisis is spreading everywhere.
It is urgent to solve the global arable land crisis.
Which Crop to Target?
After detailed researching, we decided to choose starch
as a target to design the land-free agriculture paradigm.
The reasons are as follows:
In fact, it is one of the crops with the most abundant production globally.
Showed on the right is a prechart describing how much each type of crops
takes in all the crop production worldwide every year (Item: billion ton).

Our Design
"Star-Chlamy"
We modify Chlamydomonas reinhardtii starch synthesis pathway
for higher
starch synthesis and
manageable amylose content.
Besides, we
try to crack the main barrier for its industrial production, which lies in
its CCM and light capture in photosynthesis.

We are dedicated to screening better promoters for our hard-to-serve chassis organism and to predicting the percentage of different starch synthesized in metabolic pathway.

We survey the possibility of our strains to be applied in real factory cultivation of Chlamy and to what degree will they make a difference to starch production efficiency.
