Proline and ROS: A Unified Mechanism in Plant Development and Stress Response?

Plants
The proteinogenic amino acid proline plays crucial roles in both plant development and stress responses, far exceeding its role in protein synthesis. However, the molecular mechanisms and the relative importance of these additional functions of proline ...

Abscisic acid mediated proline biosynthesis and antioxidant ability in roots of two different rice genotypes under hypoxic stress

BMC Plant Biology, 2020
Background Abscisic acid (ABA) and proline play important roles in rice acclimation to different stress conditions. To study whether cross-talk exists between ABA and proline, their roles in rice acclimation to hypoxia, rice growth, root oxidative damage

Accumulation of Proline in Plants under Contaminated Soils—Are We on the Same Page?

Antioxidants, 2023
Agricultural soil degradation is occurring at unprecedented rates, not only as an indirect effect of climate change (CC) but also due to intensified agricultural practices which affect soil properties and biodiversity.

Combined Effect of Salicylic Acid and Proline Mitigates Drought Stress in Rice (Oryza sativa L.) through the Modulation of Physiological Attributes and Antioxidant Enzymes

Antioxidants, 2023
Salicylic acid (SA) and proline exhibit protective effects against a wide range of stresses. However, the combined impact of SA and proline on rice under drought stress is still unknown.

Cancer-associated fibroblasts require proline synthesis by PYCR1 for the deposition of pro-tumorigenic extracellular matrix

Nature Metabolism, 2022
Elevated production of collagen-rich extracellular matrix is a hallmark of cancer-associated fibroblasts (CAFs) and a central driver of cancer aggressiveness.

Mitochondrial NADP(H) generation is essential for proline biosynthesis

Science, 2021
Providing for protein synthesis Compartmentalization of metabolic processes into organelles can have important consequences. Zhu et al. examined the role of the coenzyme nicotinamide adenine dinucleotide phosphate (NADP+) and its reduced form (NADPH) in ...

Intriguing Role of Proline in Redox Potential Conferring High Temperature Stress Tolerance

Frontiers in Plant Science, 2022
Proline is a proteinogenic amino acid synthesized from glutamate and ornithine. Pyrroline-5-carboxylate synthetase and pyrroline-5-carboxylate reductase are the two key enzymes involved in proline synthesis from glutamate.

Evaluation of Silicon and Proline Application on the Oxidative Machinery in Drought-Stressed Sugar Beet

Antioxidants, 2021
Drought stress deleteriously affects growth, development and productivity in plants. So, we examined the silicon effect (2 mmol) and proline (10 mmol) individually or the combination (Si + proline) in alleviating the harmful effect of drought on total ...
