“…Biotechnological interventions, including biofortification and enhanced nutrient uptake, can improve the nutrient efficiency of crops grown in oasis ecosystems. Genetically engineered crops with enhanced nutrient uptake mechanisms or increased nutrient content can address micronutrient deficiencies prevalent in oasis communities, thus improving food security and nutrition (Adhikari et al, 2023).…”

Revitalizing oasis agriculture, an age-old human endeavor, has historically played a crucial role in sustaining biodiversity and ecosystems in arid regions. Nevertheless, this enduring practice now faces contemporary challenges, including global warming, water scarcity, soil erosion, and negative human activities associated with urbanization. This comprehensive review delves into diverse literature across disciplines, covering topics such as water conservation, biodiversity restoration, agroforestry, and Oasis Holistic Management, with the aim of addressing these challenges. The analysis strongly advocates for the urgent adoption of sustainable practices, including precision irrigation, polyculture, organic farming, agroforestry, and community-based initiatives, to ensure the survival of oasis agriculture and foster long-term environmental and social responsibility. The study underscores the imperative need for the development of “comprehensive, flexible, and forward-looking management strategies” to guide the sustainable revival of oasis farming. By consolidating information from various studies, it lays the groundwork for informed decision-making and policy formulation. As part of revitalizing the oasis agricultural ecosystem and addressing the global climate crisis, we propose a noninvasive tool for assessing carbon sequestration effectiveness based on tree specifications. Recognizing the pivotal role of vegetation in mitigating the ecological impact and facing global crises, we explored parameters influencing plant carbon sequestration, including biomass production, growth rate, longevity, root structure, leaf structure, and average temperature tolerance.

“…The identified 77 K + -permeable channel genes in Arabidopsis were classified into two major groups: 15 genes of K + -selective channels (9 Shaker and 6 tandem-pore K + channels) and 62 genes of nonselective cation channels (NSCCs) which include 1 two-pore channel (TPC), 20 cyclic-nucleotide-gated channels (CNGCs), 20 ionotropic glutamate receptors (iGLRs), 10 mechanosensitive-like channels (MSLs), 2 “Mid1-Complementing Activity” channels (MCAs), 1 mechanosensitive Piezo channel, and 8 annexins [ 168 , 169 , 170 ]. This review examines how salt stress affects the functions of each K + channel.…”

High concentrations of sodium (Na+), chloride (Cl−), calcium (Ca2+), and sulphate (SO42−) are frequently found in saline soils. Crop plants cannot successfully develop and produce because salt stress impairs the uptake of Ca2+, potassium (K+), and water into plant cells. Different intracellular and extracellular ionic concentrations change with salinity, including those of Ca2+, K+, and protons. These cations serve as stress signaling molecules in addition to being essential for ionic homeostasis and nutrition. Maintaining an appropriate K+:Na+ ratio is one crucial plant mechanism for salt tolerance, which is a complicated trait. Another important mechanism is the ability for fast extrusion of Na+ from the cytosol. Ca2+ is established as a ubiquitous secondary messenger, which transmits various stress signals into metabolic alterations that cause adaptive responses. When plants are under stress, the cytosolic-free Ca2+ concentration can rise to 10 times or more from its resting level of 50–100 nanomolar. Reactive oxygen species (ROS) are linked to the Ca2+ alterations and are produced by stress. Depending on the type, frequency, and intensity of the stress, the cytosolic Ca2+ signals oscillate, are transient, or persist for a longer period and exhibit specific “signatures”. Both the influx and efflux of Ca2+ affect the length and amplitude of the signal. According to several reports, under stress Ca2+ alterations can occur not only in the cytoplasm of the cell but also in the cell walls, nucleus, and other cell organelles and the Ca2+ waves propagate through the whole plant. Here, we will focus on how wheat and other important crops absorb Na+, K+, and Cl− when plants are under salt stress, as well as how Ca2+, K+, and pH cause intracellular signaling and homeostasis. Similar mechanisms in the model plant Arabidopsis will also be considered. Knowledge of these processes is important for understanding how plants react to salinity stress and for the development of tolerant crops.

“…Micronutrients present in the soil are essential for plant physiological processes, contributing to hormonal metabolism, protein synthesis, improvement of plant defense mechanisms, and maintenance of biological membranes, among others [122][123][124]. Many chemical fertilizers have been administered to maintain nutrient supply for plant growth, but they often become unavailable due to complexation with soil particles.…”

Population growth and the need for increased agricultural productivity pose a global problem. Therefore, the development of green compounds to ensure agricultural sustainability becomes an urgent necessity. Surfactant compounds hold significant commercial importance due to their diverse industrial uses. However, the synthetic origin of these agents limits their commercial application due to their toxicity. As a result, extensive research has focused on the production of microbial-originated green surfactants, known as biosurfactants, over the past fifteen years. These biomolecules not only offer a green alternative for agriculture but also exhibit reduced toxicity and excellent stability under specific environmental conditions. Biosurfactants can lower surface tension more effectively than synthetic surfactants. With properties such as detergency and foam formation, biosurfactants are suitable for various agricultural applications, particularly in pesticide and agrochemical formulations. They can function as biopesticides to manage pests, pathogens, phytopathogenic fungi, and weeds due to their antimicrobial activity. Moreover, plants can benefit from biosurfactant molecules and the microorganisms as nutrients. They can also aid efficiently in the distribution of micronutrients and metals in the soil. They also stimulate plant immunity and are utilized for soil hydrophilization to ensure proper moisture levels and uniform fertilizer distribution. This review aims to provide valuable insights into the role and properties of biosurfactants as agricultural adjuvants, fostering the development of sustainable formulations to replace chemical surfactants used in pesticides.
