Abel, one of the most valuable woody oil plants, has been widely cultivated for extracting edible oil. The shell of is a by-product generated in the processing of edible oil extraction. However, there is still limited research on the maturity and high-value resource utilization of shell by-products. We found that the 'Huashuo' (HS) fruit shells contained a high content of catechins. Abscisic acid (ABA) and methyl jasmonate (MeJA) enhanced the accumulation of catechins in fruit shells, providing a basis for production and application of the catechins in fruit shells of . We further found that 500 μM ABA and 900 μM MeJA significantly promoted the accumulation of catechin (C) and epicatechin (EC) in fruit shells. Following treatment with 900 μM MeJA, the expressions of , , , , , , , , , , , and were significantly upregulated, while after 500 μM ABA treatment the expressions of , , , , , , , , , , and increased dramatically. These results indicate that appropriate concentrations of ABA and MeJA activate C and EC biosynthesis and promote their accumulation in fruit shells. Our results provide new ideas and guidance for promoting the resource utilization of fruit shells.
阿月浑子是最具价值的木本油料植物之一，已被广泛种植用于提取食用油。阿月浑子的果壳是食用油提取加工过程中产生的副产品。然而，关于果壳副产品的成熟度和高价值资源利用的研究仍然有限。我们发现阿月浑子‘华硕’（HS）果壳中儿茶素含量很高。脱落酸（ABA）和茉莉酸甲酯（MeJA）可增强阿月浑子果壳中儿茶素的积累，为阿月浑子果壳中儿茶素的生产和应用提供了依据。我们进一步发现，500 μM ABA和900 μM MeJA显著促进了果壳中儿茶素（C）和表儿茶素（EC）的积累。用900 μM MeJA处理后， 、 、 、 、 、 、 、 、 、 、 和 的表达显著上调，而在500 μM ABA处理后， 、 、 、 、 、 、 、 、 、 和 的表达急剧增加。这些结果表明，适当浓度的ABA和MeJA可激活C和EC的生物合成并促进它们在果壳中的积累。我们的研究结果为促进阿月浑子果壳的资源利用提供了新的思路和指导。
