生长素和独脚金内酯（SL）是两种重要的植物激素，与植物枝条的分枝和形态有关。番茄（Solanum lycopersicum L.），茄科茄属植物，是世界上最受欢迎的粮食作物之一，具有很高的经济价值。为了更好地理解外源激素的反应，进行了用外源生长素和SL单独或一起处理的番茄芽的转录组分析。在IAA、GR 24和IAA+ GR 24处理下，分别鉴定出2326、260和1379个差异表达基因。网络分析指出两个丰富的相互作用簇，包括“乙烯生物合成”和“光合作用”。在IAA和IAA+ GR 24处理下，乙烯生物合成和代谢相关基因表达上调，表明它们参与了乙烯生物合成的调控。此外，生长素-SL-触发的几个CAB基因的表达可能导致光合诱导的系统性增加。GR 24处理可抑制生长素激活的几条代谢途径，表明生长素与SL之间的相互作用可能参与了番茄的代谢调控。进一步的分析表明，SL通过诱导一系列生长素下游基因的表达来影响番茄幼苗对生长素的反应。另一方面，生长素通过影响类胡萝卜素合成途径中的基因来调控SL的合成。我们的数据将为我们揭示生长素和SL在番茄芽中的相互作用提供一个机会。
Auxin and strigolactone (SL) are two important phytohormones involved in shoot branching and morphology. Tomato (Solanum lycopersicum L.), a member of the Solanaceae family, is one of the most popular food crops with high economic value in the world. To seek a better understanding of the responses to exogenous hormones, transcriptome analyses of the tomato shoots treated with exogenous auxin and SL, separately or together, were performed. A total of 2326, 260 and 1379 differential expressed genes (DEGs) were identified under the IAA, GR24 and IAA+GR24 treatments, respectively. Network analysis pointed out two enriched interaction clusters, including “ethylene biosynthesis” and “photosynthesis”. Several ethylene biosynthesis and metabolism-related genes were up-regulated under both IAA and IAA+GR24 treatments, suggesting their involvement in the regulation of ethylene biosynthesis. Besides, auxin-SLs-triggered the expression of several CAB genes may lead to systemic increases in the induction of photosynthesis. Several auxin-activated metabolic pathways could be reduced by the GR24 treatment, indicated that the crosstalk between auxin and SLs may be involved in the metabolic regulation of tomato. Further analysis showed that SLs affect the responses of tomato shoots to auxin by inducing the expression of a series of auxin downstream genes. On the other hand, auxin regulated the biosynthesis of SLs by affecting the genes in the “Carotenoid biosynthesis” pathway. Our data will give us an opportunity to reveal the crosstalk between auxin and SLs in the shoots of tomato.
