How does sucrose promote fiber elongation?
4 answers
Sucrose plays a crucial role in promoting fiber elongation in cotton plants. Sucrose is the primary substrate for cellulose synthesis and energy production, providing turgor pressure essential for fiber elongation. The regulation of sucrose transport into expanding fibers is controlled by transcription factors like GhMYB212, which directly influence the expression of sucrose transporter genes like GhSWEET12. Manipulating intracellular sucrose pools through the overexpression of sucrose phosphate synthase (SPS) leads to increased fiber length and plant growth, confirming the importance of sucrose availability in fiber elongation. Additionally, sucrose degradation mediated by sucrose synthase (Sus) and the temporary closure of fiber plasmodesmata due to callose deposition are critical mechanisms for fiber elongation and cellulose synthesis.
What are the difference between Online versus Offline HAR ?
5 answers
Online and offline techniques differ in various aspects for different applications. In the context of Raman pump power optimization, machine learning (offline) and evolutionary strategy (online) methods were compared. Online methods in distributed systems involve server operations triggered by online or offline instructions, ensuring client stability. On the other hand, an online and offline real-time interactive game system integrates cloud servers, internet clients, and offline player equipment for rapid synchronization and enhanced gaming experience. While online approaches are suitable for real-time interactions and quick data synchronization, offline methods are preferred for certain tasks like optimization where time-consuming reconfigurations are acceptable. Each method has its strengths and is chosen based on the specific requirements of the system or application.
