Item Interfiber Competition in Textile Mills Over Time(Southern Agricultural Economics Association, 1994-07) Ethridge, Don E.; Fletcher, Stanely M.; Zhang, PingCotton and synthetic fiber competition in textile mills between 1961-1990 was examined using a time-varying parameter regression model. Results indicate that the structure of demand for cotton is not stable and cotton's share responses to changes in the prices of cotton and synthetic fiber vary over time. Cotton and synthetic fiber competition in textile mill use is essentially between cotton and noncellulosic fiber. Cellulosic fiber is not a cotton competitor.Item MYB70 modulates seed germination and root system development in Arabidopsis(2021) Wan, Jinpeng; Wang, Ruling; Zhang, Ping; Sun, Liangliang; Ju, Qiong; Huang, Haodong; Lü, Shiyou; Tran, Lam-Son Phan (TTU); Xu, JinCrosstalk among ABA, auxin, and ROS plays critical roles in modulating seed germination, root growth, and suberization. However, the underlying molecular mechanisms remain largely elusive. Here, MYB70, a R2R3-MYB transcription factor was shown to be a key component of these processes in Arabidopsis thaliana. myb70 seeds displayed decreased sensitivity, while MYB70-overexpressing OX70 seeds showed increased sensitivity in germination in response to exogenous ABA through MYB70 physical interaction with ABI5 protein, leading to enhanced stabilization of ABI5. Furthermore, MYB70 modulates root system development (RSA) which is associated with increased conjugated IAA content and H2O2/O2⋅− ratio but reduced root suberin deposition, consequently affecting nutrient uptake. In support of these data, MYB70 positively regulates the expression of auxin conjugation-related GH3, while negatively peroxidase-encoding and suberin biosynthesis-related genes. Our findings collectively revealed a previously uncharacterized component that modulates ABA and auxin signaling pathways, H2O2/O2⋅− balance, and suberization, consequently regulating RSA and seed germination.Item Projecting U.S. cotton prices in an international market(Texas Tech University, 1991-05) Zhang, Ping.
