Highly efficient -mediated hairy root transformation in citrus seeds and its application in gene functional analysis.

Highly efficient genetic transformation technology is beneficial for plant gene functional research and molecular improvement breeding. However, the most commonly used -mediated genetic transformation technology is time-consuming and recalcitrant for some woody plants such as citrus, hampering the high-throughput functional analysis of citrus genes. Thus, we dedicated to develop a rapid, simple, and highly efficient hairy root transformation system induced by to analyze citrus gene function.

Progress of clinical study on hypofractionated radiotherapy after breast-conserving surgery.

Whole-breast radiotherapy after breast-conserving surgery (BCS) can improve patient survival while reducing local tumor recurrence. Although standard breast radiotherapy can achieve good tumor control and cosmetic effects with low toxicity, the 5- to 7-week treatment time is relatively long for patients and can result in wasted medical resources. Therefore, there is a growing trend toward hypofractionated radiotherapy (HFRT), which accelerates partial-breast irradiation.

[Quantitative estimation source of urban atmospheric CO2 by carbon isotope composition].

To effectively reduce urban carbon emissions and verify the effectiveness of currently project for urban carbon emission reduction, quantitative estimation sources of urban atmospheric CO2 correctly is necessary. Since little fractionation of carbon isotope exists in the transportation from pollution sources to the receptor, the carbon isotope composition can be used for source apportionment. In the present study, a method was established to quantitatively estimate the source of urban atmospheric CO2 by the carbon isotope composition.
