Article
Full-text available
Otostegia fruticosa (Forssk.) Schweinf. ex Penz. plant is native to eastern Africa and the Middle East. This study is the first work for barcoding of Otostegia fruticosa subsp. fruticosa in Saudi Arabia with six specific primers (ITS, ITS2, matK, rbcL, TrnH-trnH2 and TrnH-GUG) and evaluating which one of these primers is more efficient than the oth...

Garden pea (Pisum sativum L.), a member of the Fabaceae family, is one of the most important self-pollinating legume crops. Globally, the pea is an economic crop, utilized as food, feed and industrial uses. Garden pea is an annual winter-season crop grown around the world from winter to early summer depending on the country. Gene banks have conserv...

Wheat is a major nutritional cereal crop that has economic and strategic value worldwide. The sustainability of this extraordinary crop is facing critical challenges globally, particularly leaf rust disease, which causes endless problems for wheat farmers and countries and negatively affects humanity’s food security. Developing effective marker-ass...

Full-text available
Tomato (Solanum lycopersicum L.) is one of the most popular vegetable species grown worldwide. Functional genomic analysis of genes in the early flower and fruit stages are the key factors for genetic enhancement of tomato fruits for increased yield and quality. In the current study, RNA-Seq datasets were generated for the Chico cultivar at six gro...

Mesembryanthemum forskalii, commonly called Forskal Fig-marigold and locally, Samh, is a wild plant, grown naturally in Saudi and Egyptian deserts and in many countries around the world. However, nutrition value, especially its protein content, has not been studied until now. Here, we explored this plant as a new source of protein, particularly in...
Article
Full-text available
Climate change has increasing effects on horticultural crops. To investigate the impact of CO2 and temperature at elevated levels on tomato production and quality of fruits an experiment was conducted by growing plants in open top chambers. The tomato plants were raised at EC550 (elevated CO2 at 550 ppm) and EC700 (elevated CO2 at 700 ppm) alone an...
Article
Full-text available
The molecular identification of different taxa of genus Acacia plays a critical role to understand the evolutionary history of this important plant that has many medicinal and ecological benefits and distributed in many regions around the world (Africa, Asia, Australia and the Americas). This is the first study that used DNA barcoding (rbcL and mat...
Article
Full-text available
A resemble in Acacia s.l. spp. morphology causes a great confusion about its identification. So, the current study's objectives are using morphological and molecular traits for accurate identification of Acacia s.l. taxa, assess the discrimination of the newly proposed genera of Vachellia and Senegalia and detect the genetic variations between stud...

Phoenix dactylifera L. (Date palm) is the most important crop in several drought regions of North Africa, the Middle East and Arabian Peninsula.Salinity is one of the main problems that can severely affect the production of Date palm.So, the objective of this study was to investigate biochemical and physiological basis for date palm salinity tolera...
Article
Severe water shortage limits horticultural crop growth and development, thereby compromising plant quality. Novel tools to enhance stress tolerance in medicinal horticultural crops are crucial to cope with growing environmental challenges to world crop performance. In this study, water solutions of robinin (25, 100, and 200 ppm) and/or foliar spray...
Article
Full-text available
Food borne pathogens cause serious human illnesses and diseases and their control using natural bioactive compounds becomes essential for the progress of agricultural and food industries. Developing novel tools to enhance the medicinal values of traditional horticultural medicinal crops is one of the promising methods for achieving food borne patho...
Article
Full-text available
Salinity stress as a major agricultural limiting factor may influence the chemical composition and bioactivity of Rosmarinus officinallis L. essential oils and leaf extracts. The application of salicylic acid (SA) hormone may alleviate salinity stress by modifying the chemical composition, gene expression and bioactivity of plant secondary metaboli...
Article
Full-text available
The negative effects of the ongoing climate change include unusual prolonged droughts and increased salinity pressures on the agricultural lands. Consequently, crops are facing unprecedented environmental pressure, and this calls for more research toward controlling such major stresses. The current study investigates the effects of seaweed extract...
Article
Full-text available
Amplified length polymorphism (AFLP) technique was used to characterize and detect molecular genetic markers for four Salsola species collected from Al Jouf region in the northern of Saudi Arabia and to shed light on their genetic relationships. Three primer combinations were used for AFLP analysis of the four Salsola species, they generated a tota...

The present investigation was carried out to detect physiological and molecular markers for salt tolerance in barley. Four cultivars of barley were screened for their tolerance against salt stress (9000 ppm). with respect to the performance of some physiological parameters such as germination percentage and abscisic acid (ABA) content and develop R...
Article
Full-text available
The impact of heat stress on the morphological, biochemical and molecular studies was examined in four cotton genotypes (Gossypium hirsutum L.) grown at control (30°C) and heat stress (40°C). Significant reduction appeared in morphological criteria (shoot length, root length, fresh and dry weight of seedlings), photosynthetic pigments, proline and...

In the present work, olive plant (Olea europaea L.) was used as a biological indicator for pollution in which, molecular and physiological parameters were studied. Olive plants were collected from polluted and non-polluted areas in Jeddah - Saudi Arabia, traffic area as an air polluted area, sewage treatment station as water polluted area, industri...

The genus Alkanna is a member of the family Boraginaceae and is found throughout temperate and subtropical areas of the world, with a major centre of distribution in the Mediterranean region. Two subspecies of Alkanna tinctoria L. (Alkanna tinctoria tripolitana and Alkanna tinctoria tinctoria) are endemic to Libya. Flower size and flower colour wer...
