“…Proline, an amino acid, is highly beneficial in plants exposed to various stress conditions. Besides acting as an excellent osmolyte, proline plays three significant roles during stress, i.e., as a metal chelator, an antioxidative defense molecule and a signaling molecule 15,16 .…”

The experiment was carried out in the winter of season 2021-2022 in the research field of the College of Agriculture - University of Basra (latitude 30.57° North and longitude 47.80°) to study the effect of foliar spraying of silicon, humic acid, and proline on the endurance of safflower (Carthamus tinctorius L.) to salt stress. The experiment was carried out by distributing eight treatments of foliar spraying. Silicon (Si) was sprayed at a concentration of 800 ppm, humic acid (H) at a concentration of 80 ppm, and proline (P) at a concentration of 100 ppm. The studied treatments included control (C), Si, H, P, SiH, SiP, HP, and SiHP) on two soils with salinity (7.63 and 14.24 ds m-1) randomized complete block design with three replicates. The seeds of safflower (Cv. Gila) were planted in the two soils. The results showed significant superiority of the triple treatment (SiHP) in all studied traits, as it recorded the highest mean of height (156.3 cm), number of bells in the plant 59.11, number of seeds in the bell (59.17), weight of 500 seeds (24.30 g), seeds yield (10549 kg seeds ha-1) and biological yield (27582 kg ha-1) with a significant increase over the control treatment, which amounted to 64.2 cm, 26.08 bell plant-1, 24.90 seed bell-1, 14.03 g, 1725 kg seeds ha-1 and 6594 kg.ha-1 respectively—superiority of the proline treatment in all studied traits. Salinity decreased the number of seeds in the plant, the weight of 500 seeds, and seed yield. The foliar spray with the above treatments has proven its effectiveness and efficiency in growth and yield and increased salinity tolerance, in addition to the fact that these materials are environmentally friendly.

Caged Proline in Photoinitiated Organocatalysis

et al. 2019

Organocatalysis is an emerging field in which small metal-free organic structures catalyze a diversity of reactions with remarkable stereoselectivity. The ability to selectively switch on such pathways upon demand has proven to be a valuable tool in biological systems. Light as a trigger provides the ultimate spatial and temporal control of activation. However, there have been limited examples of photo triggered catalytic systems. Herein, we describe the synthesis and application of a caged proline system that can initiate organocatalysis upon irradiation. The caged proline was generated using the highly efficient 4-carboxy-5,7-dinitroindolinyl (CDNI) photocleavable protecting group in a 4-step synthesis. Advantages of this system include water solubility, biocompatibility, high quantum yield for catalyst release, and responsiveness to two-photon excitation. We showed the light triggered catalysis of a crossed aldol, a Mannich, and a self-aldol condensation reaction. We also demonstrated light initiated catalysis leading to the formation of a biocide in situ, which resulted in the growth inhibition of E. coli, with as little as 3 minutes of irradiation. This technique can be broadly applied to other systems by which the formation of active forms of drugs can be catalytically assembled remotely via two-photon irradiation.

“…The accumulation of Na+ in the vacuole stimulates the synthesis of osmoprotective solutes to balance the osmotic potential of the cytoplasm with that of the vacuole [80][81][82][83]. In olive, the accumulation of osmolytes in the cytoplasm has been shown to be an adaptive mechanism against salt stress.…”

Tolerance Mechanisms of Olive Tree (<em>Olea europaea</em>) Under Saline Conditions

The olive tree (Olea europaea L.) is an evergreen tree that occupies 19% of the woody crop area and is cultivated in 67 countries on five continents. The largest olive production is concentrated in the Mediterranean basin, where the olive tree has had an enormous economic, cultural and environmental impact since the 7th century BC. In the Mediterranean region, salinity stands out as one of the main abiotic stress factors significantly affecting agricultural production. Moreover, climate change is expected to lead to increased salinisation in this region, threatening olive productivity. Salt stress causes combined damage by osmotic stress and ionic toxicity, restricting olive growth and interfering with multiple metabolic processes. A large variability in salinity tolerance among olive cultivars has been described. This paper aims to synthesize information from the published literature on olive adaptations to salt stress and its importance in salinity tolerance. The morphological, physiological, biochemical, and molecular mechanisms of olive tolerance to salt stress are reviewed.
