Article Synopsis
- Improving nitrogen use efficiency boosts rice yields, with a focus on the carbon-nitrogen balance crucial for rice growth.
- The study involved creating transgenic rice lines that overexpress or mutate the sucrose transporter protein OsSTP1 to examine its role in nitrogen absorption at various nitrogen levels during seedling growth.
- Results indicated that overexpressing OsSTP1 led to enhanced biomass and root development, demonstrating that sugar transport from leaves to roots is vital for optimizing nitrogen uptake and can inform practices to reduce nitrogen fertilizer use.
A compact external cavity tunable laser based on a silicon hybrid micro-ring resonator is demonstrated. A theoretical model is also employed for design and analysis of the wavelength tuning performance of the device. In this model, the gain section of the device is simulated by a conventional multimode rate equation model, whereas all rest passive sections are modeled by the frequency domain method.

We discuss the simulation of this tunable laser using a two-step hybrid analysis method to obtain an optimal design of the device. A wide wavelength tuning range about 40 nm in C-band with a narrow linewidth of less than 50 kHz and wavelength accuracy of ± 1 GHz over the entire tuning range can be achieved experimentally.
