Objective: To study the effects of four kind of slow-release fertilizers on yield and quality of Coptis chinensis.
Method: One to three years C. chinensis was fertilized with slow-release fertilizers twice in April and in September. The yield and nutrient content along with quality of C. chinensis were measured after two years growth.
Result And Conclusion: All of the slow-release fertilizers increased the yield obviously, and the effect of SRF1 and SRF4 is the most significant. Comparing with control group, the N content in aerial part of 1-2 year-old C. chinensis treated with SRF1 and SRF4 was lower and P and K were higher than that of control group, and the N content in aerial part of 3 year-old C. chinensis treated with SRF1 and SRF4 was higher and P and K were higher than that of control group; The N content in the root of land 3 year-old C. chinensis treated with SRF1 and SRF4 showed no significant difference comparing with control group, and P and K were lower than that of control group, the N and P content in root of 2 year-old C. chinensis treated with SRF1 and SRF4 was higher and K were lower than that of control group. After two years growth berberine content of C. chinensis treated with SRF1, SRF2 and SRF3 were significantly increased, and total alkaloid content of C. chinensis treated with SRF1, SRF3 and SRF4 were significantly increased. We recommend that SRF4 is used as the special fertilizer for 1-year-old C. chinensis, and the SRF1 and SRF4 for 2-year-old C. chinensis, and the SRF1 for 3-year-old C. chinensis.

The most important single element of the "ground system" portion of a Mars Sample Return (MSR) Campaign is a facility referred to as the Sample Receiving Facility (SRF), which would need to be designed and equipped to receive the returned spacecraft, extract and open the sealed sample container, extract the samples from the sample tubes, and implement a set of evaluations and analyses of the samples. One of the main findings of the first MSR Sample Planning Group (MSPG, 2019a) states that "The scientific community, for reasons of scientific quality, cost, and timeliness, strongly prefers that as many sample-related investigations as possible be performed in PI-led laboratories outside containment." There are many scientific and technical reasons for this preference, including the ability to utilize advanced and customized instrumentation that may be difficult to reproduce inside in a biocontained facility, and the ability to allow multiple science investigators in different labs to perform similar or complementary analyses to confirm the reproducibility and accuracy of results.

Background: Receptor-like kinases are a prominent class of surface receptors that regulate many aspects of the plant life cycle. Despite recent advances the function of most receptor-like kinases remains elusive. Therefore, it is paramount to investigate these receptors.

To identify the genes involved in storage root formation of sweet potato (Ipomoea batatas), we performed a simplified differential display analysis on adventitious roots at different developmental stages of the storage root. The expression patterns were confirmed by semiquantitative RT-PCR analyses. As a result, 10 genes were identified as being developmentally regulated and were named SRF1-SRF10.
