Alleviation of NaCl Stress on Growth and Biochemical Traits of L. via Arbuscular Mycorrhizal Fungi Symbiosis.

Soil salinization, especially in arid and semi-arid regions, is one of the major abiotic stresses that affect plant growth. To mediate and boost plant tolerance against this abiotic stress, arbuscular mycorrhizal fungi (AMF) symbiosis is commonly thought to be an effective tool. So, the main purpose of this study was to estimate the role of AMF (applied as a consortium of , , , and species) symbiosis in mitigating deleterious salt stress effects on the growth parameters (shoot length (SL), root length (RL), shoot dry weight (SDW), root dry weight (RDW), root surface area (RSA), total root length (TRL), root volume (RV), root diameter (RD), number of nodes and leaves) of L.

Phenotypic Plasticity Strategy of Grass in Response to Heterogenous Saline Habitats.

Understanding the response variation of morphological parameters and biomass allocation of plants in heterogeneous saline environments is helpful in evaluating the internal correlation between plant phenotypic plasticity mechanism and biomass allocation. The plasticity of plants alters the interaction among individuals and their environment and consequently affects the population dynamics and aspects of community and ecosystem functioning. The current study aimed to assess the plasticity of traits with variation in saline habitats.

Volatile Oils Discrepancy between Male and Female and Their Allelopathic Activity on .

Volatile oils (VOs) composition of plants is affected by several exogenous and endogenous factors. Male and female plants of the dioecious species exhibit variation in the bioactive constituents' allocation. The chemical variation in the VOs between male and female plants is not well studied.

Vegetation Composition of the Halophytic Grass Communities within Coastal and Inland Sabkhas of Saudi Arabia.

Sabkhas are unique, highly saline ecosystems, where specially adapted plants can grow. (L.) Thwaites is a halophytic forage plant growing in salt marsh habitats of inland and coastal sabkhas of Saudi Arabia.

Essential Oil of : Comparative Chemical Profiles, Antimicrobial Activity, and Allelopathic Potential on Weeds.

Plants are considered green resources for thousands of bioactive compounds. Essential oils (EOs) are an important class of secondary compounds with various biological activities, including allelopathic and antimicrobial activities. Herein, the present study aimed to compare the chemical profiles of the EOs of the widely distributed medicinal plant collected from Saudi Arabia and Egypt.

Functional Traits Plasticity of the Invasive Herb Sweet in Different Arid Habitats.

Understanding the strategies and mechanisms of invasive species could guide their control and management especially in arid ecosystems. This study compares the vegetative and reproductive functional traits of the invasive Mexican poppy (), in seven habitat types, in southwestern Saudi Arabia. The results showed that the aboveground phenological attributes such as plant height, leaf area, and leaf dry mass attained the highest values in the wadi channels, whereas these attributes attained the lowest values in the mountain ranges.

Euphosantianane E-G: Three New Premyrsinane Type Diterpenoids from with Contribution to Chemotaxonomy.

species were widely used in traditional medicines for the treatment of several diseases. From the aerial parts of Egyptian endemic plant, , three new premyrsinane diterpenoids, namely, euphosantianane E-G (-), alongside four known triterpenes, 9,19-cyclolanostane-3β,24-diol (), 25-methoxycycloartane-3β,24-diol (), 25-methylenecycloartan-3β,24-diol (), and 25-methylenecycloartan-3β,24-diol (), were isolated and identified. The chemical structures were proven depending upon spectroscopic analysis, including FTIR, HRFABMS, and 1D/2D-NMR.
