“…CA proved to be effective in preventing the loss of other types of molecules, namely indole acetic acid and benzoic acid derivatives, which are interesting due to their an-tioxidant power [31]. Indole compounds have also relevance in the modulation of plant growth [32], with IAA (indole-3-acetic acid a phytohormone of the auxin class) being an emblematic example: auxin is crucial for root development, and the presence of an auxin gradient is important in root development and in the establishment of a root stem cell niche [33]. Benzoic acid confers tolerance to multiple stress in plants [34] and is thus important post-germination to have more resilient plants to environmental constraints.…”

Cicer arietinum L. (chickpea, or garbanzo bean) is one of the most consumed legumes worldwide. It is a rich source of carbohydrates, proteins, fibers, minerals and vitamins with very low cholesterol. From a nutritional point of view, despite the low content of fats, the seeds contain various unsaturated acids, such as linoleic and oleic acids, as well as bioactive compounds, like antioxidants, with reactive oxygen species-scavenging activities. It is known that long periods of storage can drastically affect the preservation of these compounds in seeds. For this reason, in the last few years, different methods have been tested with the aim of increasing the shelf life of economically relevant beans, seeds and cereals. A promising and eco-friendly alternative to traditional storage is the use of a controlled atmosphere, represented by N2-pressurized silos. The present study aims at evaluating the content of different compounds, e.g., fatty acids, proteins, vitamins, and molecules of nutraceutical interest, in chickpeas stored at ambient temperature in N2-pressurized silos (98.5 ± 0.5% (v/v)) and control ones (standard storage) in long-term kinetics (1 year). The results show the stable content of most compounds during the kinetics. However, vitamin E decreased in samples stored under both standard and controlled atmosphere conditions, with a more pronounced and significant decrease under standard conditions as compared to the controlled atmosphere. Additionally, samples stored under a controlled atmosphere show a total higher content of quinic, indole butyric and benzoic acid, as well as their derivates.

Dark septate endophytes (DSE) are widespread colonizers of plant roots and have important ecological functions such as the regulation of plant growth and nutrient uptake. The mechanisms by which DSE mycelium and its extracellular metabolites promote plant growth have not yet been determined. Here, the growth‐promoting effects of DSE mycelium (H) and extracellular metabolites (M) on alfalfa (Medicago sativa L.) were investigated. Treatments H, M and HM increased the total biomass of alfalfa by 23.9%, 47.2% and 47.1%, respectively. H and M modified root structure by increasing root volume and reducing root tissue density, and promoting nutrient uptake. Metabolomic analysis indicates that alfalfa root exudates contained 204 metabolites of different types, mainly lipids and lipid‐like molecules, organic acids and derivatives, benzenoids. There were more organoheterocyclic compounds and fewer organic acids and derivatives in root exudates in treatment H than in treatment M. Pathway analysis shows that DSE and its extracellular metabolites had greater effects on glycerophospholipid metabolism and N‐glycan biosynthesis pathway. The results provide information on the mechanisms involved in the metabolic regulation of plant growth promotion by DSE.

“…Agrochemicals, the result of interdisciplinary collaboration between chemists and biologists, have played a crucial role in enhancing crop productivity. Exogenous phytohormones and their related chemicals offer distinct advantages over other agrochemical agents by improving crop resistance against biotic and abiotic stresses, enhancing crop morphology, and increasing crop yield. − Phytohormones, as highly conserved chemical signals, govern essential functions in coordinating plant growth and development at both tissue and organ levels. , The nine molecules that have been defined as phytohormones are auxin (AUX), gibberellin (GA), ethylene (ETH), cytokinin (CTK), abscisic acid (ABA), brassinosteroid (BR), salicylic acid (SA), jasmonate (JA), and strigolactone (SL) . For the complex activities of plant life, the functions of phytohormones are not limited to a certain fixed role.…”

Chemicals that modulate phytohormones serve as a research tool in plant science and as products to improve crop productivity. Subtype selectivity refers to a ligand to selectively bind to specific subtypes of a receptor rather than binding to all possible subtypes indiscriminately. It allows for precise and specific control of cellular functions and is widely used in medicine. However, subtype selectivity is rarely mentioned in the realm of plant science, and it requires integrated knowledge from chemistry and biology, including structural features of small molecules as ligands, the redundancy of target proteins, and the response of signaling factors. Here, we present a comprehensive review and evaluation of phytohormone receptor subtype selectivity, leveraging the chemical characteristics of phytohormones and their analogues as clues. This work endeavors to provide a valuable research strategy that integrates knowledge from chemistry and biology to advance research efforts geared toward enhancing crop productivity.
