Special Opportunities:
|
(1) Candidates selected for our team will grasp fundamental and specific knowledge of plant physiology/ woody plant tissue culture. (2) The candidates will gain experience in using different combinations of PGRs to initiate callus formation from stems or leaf pieces, adventitious bud differentiation from callus, and rooting of regenerated plantlets. (3) The candidates will master practical hands-on skills in plant tissue culture and advanced general biology technologies. (4) The candidates will receive opportunities to present their research findings at scientific workshops, such as TAMU Student Research Week, Biology Undergraduate Research Symposium.

Description:
|
Crapemyrtle is the highest-selling deciduous flowering tree in the U.S.– 3.03 million plants with a combined value of $69.57 million were sold in 2019. By virtue of its wide distribution and long blooming period, crapemyrtle provides excellent pollen sources for native and non-native bees in the U.S., especially when other resources are naturally scarce. However, most of the crapemyrtle plants in the U.S. are Lagerstroemia limii, Lagerstroemia fauriei, and their hybrids. They are susceptible to crapemyrtle aphid (CMA) and crapemyrtle bark scale (CMBS), which pose a devastating risk to the Green Industry of crapemyrtle. The infestation engendered a significant decrease in the sale number and price value of crapemyrtle anticipated by the Green Industry. According to our previous research, Queen’s crapemyrtle (L. speciosa) is resistant to the invasive polyphagous insect, crapemyrtle bark scale. The final goal of this project is to develop a plant tissue culture protocol to proliferate Queen’s crapemyrtle. Four objectives will be involved: (1) Obtain contamination-free plantlets of Queen’s crapemyrtle via micropropagation, which can consistently provide fresh materials for establishing the regeneration system. (2) Induce callus from leaf pieces and stems of Queen’s crapemyrtle using different plant growth regulators (PGRs), which play an essential role in the regeneration establishment. (3) Differentiate adventitious buds from callus of Queen’s crapemyrtle using an optimum PGRs combination, which is a vital step in the regeneration establishment. (4) Rooting of the regenerated Queen’s crapemyrtle plantlet |
