在开始撰写 MS/MS.qmd 前完成本文件，并在第一次讨论中确认。只写当前最可靠的判断；未知事项应明确标出，而不是用猜测填满。

1. 核心问题与假设 / Core question and hypothesis

  • 科学问题 / Research question: Can qPCR rapidly quantify both Anabaena abundance and geosmin-producing potential in freshwater systems?
  • 可检验假设 / Testable hypothesis: ARG copy number tracks microscopic Anabaena counts, while GSG copy number tracks geosmin concentration measured by GC-MS.
  • 研究缺口与必要性 / Gap and why it matters: Microscopy and GC-MS are slow, equipment-intensive, and require specialist expertise during odor events.

2. 主要结果与图 / Main findings and figures

主张 / Claim 支持它的结果 / Evidence 主图或表 / Main figure or table 仍需验证 / Remaining uncertainty
ARG qPCR estimates Anabaena abundance Microscopic count: \(r^2 = 0.726\), \(p < 0.001\); LOD/LOQ 0.02/0.2 pg DNA MS/MS_results.qmd, ARG comparison figure Verify against raw counts and assay records
GSG qPCR estimates geosmin-producing potential GC-MS comparison: \(r^2 = 0.742\), \(p < 0.001\) MS/MS_results.qmd, GSG comparison figure Verify calibration and independent units

3. 文章故事线 / Paper story

  • 暂定英文标题 / Working English title: Establishment of quantitative PCR methods for the quantification of geosmin-producing potential and Anabaena sp. in freshwater systems
  • 暂定中文标题 / Working Chinese title: 淡水系统中产土臭素潜力与鱼腥藻定量 PCR 方法的建立
  • 引言逻辑（3–5 句）/ Introduction logic (3–5 sentences): Geosmin events require rapid detection. Existing microscopy and GC-MS workflows are slow or difficult to deploy. ARG and GSG provide candidate molecular markers for abundance and production potential. The study validates both assays in cultures and field samples.
  • 讨论与结论（3–5 句）/ Discussion and conclusion (3–5 sentences): Both assays correlate with conventional measurements and support faster monitoring. ARG is useful for tracking Anabaena populations; GSG provides a proxy for geosmin production potential. The methods are screening tools, not replacements for confirmatory GC-MS or microscopy in every setting.
  • 创新点与边界 / Novelty and scope boundary: The contribution is a paired qPCR workflow. The historical evidence supports the tested strains and sampled freshwater systems; broader taxonomic and geographic generalization remains to be audited.

4. 写作边界 / Writing constraints

  • 目标期刊与文章类型 / Target journal and article type:
  • 活动正文 / Active manuscript: MS/MS.qmd
  • 预期补充材料、数据或代码 / Expected supplements, data, or code: Legacy supporting material in input/legacy/lastsubmit/Supporting.tex; raw data in data/raw/legacy/; analysis script in input/legacy/data/DataAnalysis.R.
  • 作者与贡献中尚未确认的事项 / Authorship or contribution decisions pending:

5. 首次讨论需决定的问题 / Decisions needed at the first meeting
