The Scotch broom gall mite, Aceria genistae, attacks Cytisus scoparius (Scotch broom), an invasive shrub in California, USA. Feeding causes galls (localized tissue distortion) but the effect of A. genistae on overall host vigor and reproduction has not been assessed. We collected data on plant parts between two plants partitioned between two groups, heavily or lightly galled plants, at three northern California sites. Plant parts were measured in the field (plant height, plant width) and others were recorded after harvesting plants (stem, leaf, gall, seed pod, seeds, etc.) and drying them in an oven to a constant weight. Data were natural log transformed. Columns represent (in order): observation number (obs), plant identifier (plantID), Site, treatment (heavy or light galling), Diameter at soil (lnDAS), height, leaf weight (lnLeaf), stem weight (lnStem), fruit weight (lnFruit), gall weight (lnGalls), number of pods (lnpods), seed weight (lnseeds), number of seeds per plant (lnseedsplant), canopy volume (lnVol), canopy diameter at its widest point (lnWidest), canopy area (lnCanopyArea), total biomass of all plant fractions combined (lnTotal), number of stem branches (lnResource).

金雀花瘿螨（Scotch broom gall mite，学名Aceria genistae）可侵染金雀儿（Cytisus scoparius，俗称Scotch broom）——一种美国加利福尼亚州的入侵灌木。该螨的取食行为会诱导寄主形成虫瘿（局部组织畸形），但目前尚未明确Aceria genistae对寄主整体生长势与繁殖能力的影响。

本研究在美国加利福尼亚州北部的3个采样点，将供试植株按瘿螨侵染程度划分为重度虫瘿组与轻度虫瘿组两类，采集了两类植株各组织的相关数据。

部分植株性状在野外直接测定（包括株高、冠幅宽度），其余性状则在采集植株后，经烘箱烘干至恒重，再对茎、叶、虫瘿、荚果、种子等组织进行量化记录。所有数据均经过自然对数转换处理。

各数据列依次为：观测编号（observation number，缩写obs）、植株标识符（plant identifier，缩写plantID）、采样点（Site）、侵染处理（重度或轻度虫瘿侵染，treatment）、基径（Diameter at soil，缩写lnDAS）、株高（height）、叶重量（leaf weight，缩写lnLeaf）、茎重量（stem weight，缩写lnStem）、果重量（fruit weight，缩写lnFruit）、虫瘿重量（gall weight，缩写lnGalls）、荚果数量（number of pods，缩写lnpods）、种子重量（seed weight，缩写lnseeds）、单株种子数（number of seeds per plant，缩写lnseedsplant）、冠幅体积（canopy volume，缩写lnVol）、冠幅最大直径（canopy diameter at its widest point，缩写lnWidest）、冠幅面积（canopy area，缩写lnCanopyArea）、所有植株组分总生物量（total biomass of all plant fractions combined，缩写lnTotal）、茎分枝数（number of stem branches，缩写lnResource）。
