Soil phosphorus (P) plays a vital role in both ecological and agricultural ecosystems, where total P (TP) in soil serves as a crucial indicator of soil fertility and quality. Most of the studies covered in the literature employ a single or narrow range of soil databases, which largely overlooks the impact of utilizing multiple mapping scales in estimating soil TP, especially in hilly topographies. In this study, Fujian Province, a subtropical hilly region along China’s southeast coast covered by a complex topographic environment, was taken as a case study. The influence of the mapping scale on soil TP storage (TPS)estimation was analyzed using six digital soil databases that were derived from 3 082 unique soil profiles at different mapping scales, i.e., 1:50 000 (S5),1:200 000 (S20), 1:500 000 (S50), 1:1 000 000 (S100), 1:4 000 000 (S400), and 1:10 000 000 (S1000). The regional TPS in the surface soil (0–20 cm) based on the S5, S20, S50, S100, S400, and S1000 soil maps was 20.72, 22.17, 23.06, 23.05, 22.04, and 23.48 Tg, respectively, and the corresponding TPS at0–100 cm soil depth was 80.98, 80.71, 85.00, 84.03, 82.96, and 86.72 Tg, respectively. By comparing soil TPS in the S20 to S1000 maps to that in the S5map, the relative deviations were 6.37%–13.32%for 0–20 cm and 0.33%–7.09%for 0–100 cm. Moreover, since the S20 map had the lowest relative deviation among different mapping scales as compared to S5, it could provide additional soil information and a richer soil environment than other smaller mapping scales. Our results also revealed that many uncertainties in soil TPS estimation originated from the lack of detailed soil information, i.e., representation and spatial variations among different soil types. From the time and labor perspectives, our work provides useful guidelines to identify the appropriate mapping scale for estimating regional soil TPS in areas like Fujian Province in subtropical China or other places with similar complex topographies.

本研究克隆了驴脂肪酸去饱和酶2(FADS2)基因并进行了生物信息学分析,检测了其在驴不同组织中的表达。通过设计FADS2基因引物,PCR克隆得到其CDS序列,然后对FADS2基因编码产物进行生物信息学预测,同时使用实时荧光定量PCR(RT-qPCR)检测驴心脏、肝脏、脾脏、肺脏、肾脏、肌肉、脂肪、乳腺内FADS2基因相对表达量。结果显示:驴FADS2基因CDS长1335 bp,可编码444个氨基酸,FADS2蛋白分子质量为52.43 ku,等电点为8.29,不稳定指数为37.22,疏水性总平均值为-0.231,属于稳定碱性亲水蛋白;FADS2蛋白二级结构主要由α-螺旋(51.80%)和无规则卷曲(37.61%)构成。FADS2基因在所检测驴组织中均有表达,其中在脂肪和乳腺中相对表达量最高,其次为脾脏、肺脏、肾脏、心脏和肝脏,肌肉中相对表达量最低。结果提示,FADS2可能在驴脂肪和乳腺等组织不饱和脂肪酸的合成过程中发挥重要作用。本研究可为进一步探究驴脂肪和驴乳中高不饱和脂肪酸的合成机理提供基础。
