Expression profiling of the BpIAA gene family and the determination of IAA levels in Betula platyphylla tetraploids
《Journal of Forestry Research》2019年第3期855-867,共13页Wendi Xu Su Chen Jing Jiang Guifeng Liu 
supported by the National Natural Science Foundation of China(Grant Nos.31370660 and 31670673);the 111 Project(B16010)
Betula platyphylla Sukaczev tetraploids have significantly larger leaf, fruit and stoma (gigantic phenotype) than diploids of the same species;however, the mechanism underlying this difference remains unclear. Tetrapl...

The Quadraplex Tetraploids Hybrids and Duplex Tetraploids Hybrids Are Responsible for Heterosis and Inbreeding Depression in Maize
《Agricultural Sciences in China》2005年第7期486-493,共8页WANGZe-li JamesABirchler WANGLu-xin JINLiang 
This study was in part supported by the Scientific Research Foundation for the Returned Overseas Chinese Scholars of Education Ministry of China;a grant from the Department of Energy Biosciences,USA,to University of Columbia,JB.
The maize quadraplex tetraploids and duplex tetraploids were developed using Kato’s protocols. The phenotype ofheterosis and inbreeding depression over generations in their parents and progenies of F1, F2 and F3 were...
