摘要

代谢物在干旱、温度和光照等恶劣环境中的稳定性表明,它们在植物缓解非生物和生物压力的过程中具有尚未开发的潜力。这些代谢物可能对微生物、植物或动物没有特异性。许多吲哚胺在整个物种中无处不在,并已被证明可以缓解各种压力。由于草莓的繁殖生命周期较短,且具有温带性状,我们通过外源应用前体色氨酸(TRP)测试了吲哚胺代谢物在草莓上的作用。以叶面喷施(3 毫克/升)和地面淋施(100 毫克/升)或仅地面淋施(100 毫克/升)相结合的方式外源施用 TRP 似乎会扰乱季节性反应。这种处理除了减轻光周期短和低温等胁迫外,还产生了刺激生长的反应。进入休眠期的植株在 11 月份的不利气候条件下重新长出绿叶并开花结果,而未经处理的植株则逐渐衰老。对处理过的植物的花和果实中的内源性吲哚胺分析表明,代谢产物 NAS、2-羟基褪黑激素和 N(1)-acetyl-N(2)-formyl-5-methoxykynuramine 的滴度和比率有助于缓解胁迫。ASMT 和 M2H 基因调控强调了 TRP 中间代谢产物的稳定性。TDC和T5H基因调控解释了在草莓中检测到一种罕见化合物--5-羟色氨酸的原因。这是首次报道在草莓中检测到八种吲哚胺以及吲哚胺途径中的调控基因。不断恶化的气候危机要求植物迅速适应气候,而吲哚胺工具包可能为开发简单有效的方法来管理植物的抗逆性提供了机会。

Stable indoleamines attenuate stress—A novel paradigm in tryptophan metabolism in plants

Stable indoleamines attenuate stress—A novel paradigm in tryptophan metabolism in plants

Stability of metabolites in harsh environments such as drought, temperature, and light suggest their untapped potential in processes the plants utilize in mitigation of abiotic and biotic stresses. Such metabolites could be nonspecific to microorganisms, plants, or animals. Many of the indoleamines are ubiquitous throughout species and have been shown to mitigate a wide range of stresses. We tested the role of indoleamine metabolites via exogenous application of the precursor tryptophan (TRP) on strawberry due to the short reproductive life cycle and its temperate traits. Seasonal responses appeared to be perturbed with exogenous application of TRP as a combination of foliar (3 mg/L) and ground drench (100 mg/L) or ground drench only (100 mg/L). The treatment yielded growth stimulatory responses besides mitigating stress, that is, short photoperiod and cold temperature. Plants preparing into dormancy reverted to produce green foliage and flowers that set fruit in unfavorable climate in the month of November where the untreated plants senesced. Analyses of the endogenous indoleamines in flowers and fruits of the treated plants indicated that the titers and ratios of the metabolites NAS, 2-hydroxymelatonin, and N(1)-acetyl-N(2)-formyl-5-methoxykynuramine assisted in the stress mitigation. The ASMT and M2H gene regulations emphasized the stability of intermediate metabolites of TRP. The TDC and T5H regulation explained the detection of a rare to find compound, 5-hydroxytryptophan, in strawberry. This is the first report on detection of eight indoleamines in strawberry alongside the regulatory genes in the indoleamine pathway. Inclining climate crisis demands climate-resilient plants in quick time and the indoleamine toolkit may offer the opportunity to develop simple and effective practices to manage stress tolerance in plants.

期刊介绍: The Journal of Pineal Research welcomes original scientific research on the pineal gland and melatonin in vertebrates, as well as the biological functions of melatonin in non-vertebrates, plants, and microorganisms. Criteria for publication include scientific importance, novelty, timeliness, and clarity of presentation. The journal considers experimental data that challenge current thinking and welcomes case reports contributing to understanding the pineal gland and melatonin research. Its aim is to serve researchers in all disciplines related to the pineal gland and melatonin.
