b. What transgenic materials do you want to receive?
Maize:
Three different transgenic products can be requested for maize.
Transgenic plantlets: this is the most popular request. We mail rooted transgenic plantlets in Petri dishes containing plant media using overnight express services. Customers can transplant the plantlets into soil and grow them to maturity in their own greenhouse. Transformation orders for Hi II genotype with plantlet request requires no waiting period. From the day of transformation to plantlet delivery typically takes about 4 months, if no intermediate callus analysis is requested (Hi II only).
Transgenic seeds: for researchers who do not have adequate greenhouse space in their own institution or for oversea researchers, we can produce transgenic seeds. However, because of limited greenhouse capacity for maize, we may not be able to process all transgenic projects requesting seed upon the arrival of the constructs. A waiting period may occur depending on project work load at the time.
Transgenic callus culture (Hi II only): Transgenic callus is an economic choice for those researchers who just want to evaluate their constructs at an early stage, or have the resources & skills to regenerate plants from transgenic callus in their own laboratories.
Rice: Both transgenic plantlets and seeds can be produced per customer's request. Because rice growth chamber space is limited, a delay may be experienced for rice seed request if seed pipeline is full at the time.
Soybean: To avoid any escapes (non-transgenic plants with false positive responses to herbicide), we only deliver T1 transgenic soybean seeds.
Brachypodium: Currently, we can only deliver T0 transgenic plantlets due to growth space limitation and unique photoperiod (20:4) required by Bd-21.
