入侵杂草刺萼龙葵Solanum rostratum Dunal传播扩散的主要载体是种子,研究其种子休眠萌发基因的激素调控对于其防除具有重要意义,而选择合适的内参基因可以提高相关基因表达分析的准确性。本研究以赤霉素、脱落酸和水处理的刺萼龙葵种子为材料,利用geNorm、NormFinder、BestKeeper和RefFinder 4种软件对15个候选内参基因进行表达稳定性评价,并通过检测ABI5(abscisic acid-insensitive 5)的表达验证所筛选的内参基因的适用性。结果表明,对于赤霉素、脱落酸和水处理过的种子,最稳定的内参基因分别为eIF(eukaryotic initiation factor)、SAND(SAND protein family)和ACT(β-actin);对所有种子样本而言,PP2Acs(a catalytic subunit of protein phosphatase 2A)是最稳定的内参基因。研究结果将为刺萼龙葵种子休眠萌发的遗传调控研究提供重要参考。 |
英文摘要: |
The main transmission way of the invasive weed buffalobur (Solanum rostratum) is seed dispersal. It is important to understand the hormonal regulation of seed dormancy or germination related genes in buffalobur. Selection of appropriate reference genes can improve the accuracy of expression analysis of these genes. Here, 15 candidate reference genes were selected to evaluate their expression stability in hormone-treated and water-treated seeds of buffalobur using geNorm, NormFinder, BestKeeper and RefFinder statistical algorithms. Validation of recommended reference genes were achieved by assessing the relative expression levels of abscisic acid-insensitive 5 (ABI5). The results showed that the most stable reference genes for gibberellin, abscisic acid and water-treated seeds were eukaryotic initiation factor (eIF), SAND protein family (SAND) and β-actin (ACT), respectively. For total seeds, PP2Acs, the gene encoding a catalytic subunit of protein phosphatase 2A was the most stable reference gene. This work would provide references for further research on the genetic regulation of seed dormancy and germination in this invasive plant. |
