Abstract

The potato serves as a crucial food crop and a significant industrial and economic mainstay in Qinghai. The impact of rhamnolipid, a typical biological fertilizer, on potato yield in Qinghai requires further investigation. This study employed transcriptome sequencing to examine the impact of rhamnolipid on potato yield in alpine locations. We adopted the Illumina platform for sequencing and examined the transcriptome of 18 potato leaf specimens. A total of 36,720 genes were functionally annotated using the GO, KEGG, NR, Swiss-Prot, Pfam, and KOG databases. Combined with physiological indices, including total chlorophyll content, total flavonoid content, and auxin content of potato leaves following rhamnolipid application. The findings indicated that rhamnolipid application enhanced the expression of differential genes regulating essential enzymes, including auxin, flavonoids, and starch in potato foliage, elucidating the molecular mechanism by which rhamnolipid increases potato yield. The findings facilitated the advancement of biological pesticides, established a theoretical foundation for the utilization of rhamnolipid in potato cultivation, offered technical assistance for achieving high and steady potato yields in Qinghai, and promoted the progression of sustainable agriculture in the plateau region.

鼠李糖脂对马铃薯生理特性及代谢途径的影响

马铃薯是青海重要的粮食作物，也是重要的工业和经济支柱。鼠李糖脂作为一种典型的生物肥料，对青海马铃薯产量的影响有待进一步研究。本研究采用转录组测序法研究鼠李糖脂对高山地区马铃薯产量的影响。我们采用Illumina测序平台，对18份马铃薯叶片样本进行转录组检测。使用GO、KEGG、NR、Swiss-Prot、Pfam和KOG数据库对总共36,720个基因进行了功能注释。结合施用鼠李糖脂后马铃薯叶片叶绿素含量、总黄酮含量、生长素含量等生理指标。结果表明，施用鼠李糖脂可提高马铃薯叶片中调控生长素、黄酮类和淀粉等必需酶的差异基因的表达，阐明了鼠李糖脂提高马铃薯产量的分子机制。研究结果促进了生物农药的发展，为鼠李糖脂在马铃薯栽培中的应用奠定了理论基础，为青海马铃薯高产稳产提供了技术支持，促进了高原地区可持续农业的发展。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
