茄科作物经济价值较高,但株型高大,种植密度受限,水肥消耗量高。植物激素通过影响细胞分裂及伸长调控植株高度,挖掘影响其矮化的激素相关基因、创制矮化资源是茄科作物品种株型改良的重要基础。本文概述了几种主要植物激素与植物矮化相关的生物学功能,重点阐述了茄科作物矮化突变与所述激素生物合成及信号转导的关系,提出了基于突变体创建,综合利用现代分子生物学技术,系统开展矮化基因挖掘与高效利用的研究思路与方法。
Solanaceae crops are economically important, but they are not suitable to be cultivated in high density and consume a large amount of water and fertilizer for their large plants. It has been well known that phytohormones play an important role in regulating plant height via modulating cell division and cell elongation. Accordingly, mining dwarf genes and creating dwarf germplasm have been the important base for improvement of plant architecture in Solanaceae crops. Here we firstly summarized the biological function of the phytohormones modulating plant height, furthermore emphasized the mechanism of hormone-related dwarf mutation in Solanaceae crops. Finially proposed a simple and efficient strategy of gene mining and utilization by modern molecular biological technique based on dwarf mutant.
