Exogenous Proline Alleviated Low Temperature Stress in Maize Embryos by Optimizing Seed Germination, Inner Proline Metabolism, Respiratory Metabolism and a Hormone Regulation Mechanism

open access: yesAgriculture, 2022
Proline (Pro) is not only an important osmotic adjustment substance, but it also plays an important role in regulating plant abiotic stress resistance. The maize varieties, Xinxin 2 (low temperature insensitive) and Damin 3307 (low temperature sensitive),

Resolving the Hydride Transfer Pathway in Oxidative Conversion of Proline to Pyrrole

open access: yes, 2022
Thiotemplated pyrrole is a prevailing intermediate in the synthesis of numerous natural products in which the pyrrole is tethered to a carrier protein (CP). Biosynthesis of the pyrrole requires oxidation of an l-proline side chain. Herein, we investigate

Exogenous Proline Enhances Systemic Defense against Salt Stress in Celery by Regulating Photosystem, Phenolic Compounds, and Antioxidant System

open access: yesPlants, 2023
This study aimed to explore how exogenous proline induces salinity tolerance in celery. We analyzed the effects of foliar spraying with 0.3 mM proline on celery growth, photosystem, phenolic compounds, and antioxidant system under salt stress (100 mM ...

Regulation of proline oxidase activity by lactate. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1977
We found that proline oxidase, the first enzyme of the proline degradative pathway, is inhibited by lactate. The Km of the enzyme for proline increases with increasing concentrations of lactate. Since proline can be a source for gluconeogenesis, regulation of proline degradation by lactate may serve as a mechanism for allocation of metabolic fuel ...

Application of sucrose modulates the expressions of genes involved in proline and polyamine metabolism in maize seedlings exposed to drought

open access: yesBiologia Plantarum, 2019
Sucrose, proline, and polyamines are compatible solutes accumulating in plant tissues and increasing cellular osmolarity under environmental stresses. These compatible solutes and hydrogen peroxide can function as signaling molecules in plants. There has
