“…A shorter duration of grain filling and a greater number of days above 25 °C resulted in a decline in linoleic acid content [ 176 ]. More recently, water-deficit stress was shown to increase oleic and linoleic acid content in C. sativa seeds, whereas linolenic acid content decreases, being dependent upon genotype, as one accession showed an increase in a-linolenic content following drought treatment [ 177 ]. Importantly, various environmental stress factors including heat, drought, salinity, high light, low oxygen, and high nitrogen can lead to decreases in overall seed oil content and changes in fatty acid composition [ 162 ].…”

Camelina sativa (L.) Crantz. is an annual oilseed crop within the Brassicaceae family. C. sativa has been grown since as early as 4000 BCE. In recent years, C. sativa received increased attention as a climate-resilient oilseed, seed meal, and biofuel (biodiesel and renewable or green diesel) crop. This renewed interest is reflected in the rapid rise in the number of peer-reviewed publications (>2300) containing “camelina” from 1997 to 2021. An overview of the origins of this ancient crop and its genetic diversity and its yield potential under hot and dry growing conditions is provided. The major biotic barriers that limit C. sativa production are summarized, including weed control, insect pests, and fungal, bacterial, and viral pathogens. Ecosystem services provided by C. sativa are also discussed. The profiles of seed oil and fatty acid composition and the many uses of seed meal and oil are discussed, including food, fodder, fuel, industrial, and medical benefits. Lastly, we outline strategies for improving this important and versatile crop to enhance its production globally in the face of a rapidly changing climate using molecular breeding, rhizosphere microbiota, genetic engineering, and genome editing approaches.

“…Furthermore, it is related that plants associated with PGPR display better relative water content, especially in abiotic stress situations (Borzoo et al, 2021). In this research, rice cultivar inoculated with B. subtilis showed highest relative water content than non-inoculated plants under water stress (Figure 5).…”

Multiple factors are threatening food security through climate change. Potential effect of this is seen in the variability of rainfall received with drought as the most critical factor that is affecting the growth and yield of plants. Plant growth promoting bacteria (PGPB) are taunted as one of the most promising organisms to counter the drastic effect of climate change especially in drought condition. They facilitate the growth of plants and helps alleviate the stresses brought by abiotic stress conditions. Three previously isolated Bacillus species labeled (SA1 (Bacillus subtilis), SA3 (Bacillus niacini) and SB1 (Bacillus cereus)) were tested for plants growth promoting enhancement in rice under water stress condition. Growth parameters; Root length, shoot length, fresh of root and dry weight of root were all tested using standard techniques. Chlorophyll content was measured using SPAD chlorophyll meter while relative water content of the leaves was calculated using a standard formula. Among all the three Bacillus species tested, Bacillus subtilis (SA1) was found to enhance all the measured growth parameters, relative water content and chlorophyll content in the rice under water stress condition to a significant extent when compared with other Bacillus species. Therefore, Bacillus subtilis (OM184294) could be a potential candidate as PGPB especially under drought conditions.

“…The compounds in the substances left by the roots, by acidifying or changing the redox conditions in the rhizosphere or directly chelating the elements, help to provide nutrients such as nitrogen, phosphorus, iron, etc. As the soil dries, the hydraulic potential decreases, after which the root seepage begins to return water to the soil, increasing the degree of stability of the rhizosphere (39)(40)(41)(42)(43)(44)(45)(46)(47)(48).…”

Worldwide biodiversity is impacted strikingly by global environmental change, and thus its impact is reflected in all life aspects. Identifying microorganisms in environmental samples, particularly soil could be a valuable interest to study their effect on soil quality and plant growth. Through this study, we conducted a molecular characterization of bacteria found in the rhizosphere of Medicago sativa plants grown in Hai'l soil and we highlighted their main properties. The analysis of sequences revealed that the main bacterial isolates were Pseudarthrobacter, Metabacillus, Priestia, and Massilia species. According to the sequence analyses and the phylogeny tree results, some of the identified bacteria were classified at the species level: one of the pseudarthrobacter isolates was identified clearly as Pseudarthrobacter phenanthrenivorans; Metabacillus isolates grouped with Metabacillus sediminilitoris and the two Priestia isolates closely related to Priestia aryabhattai. We concluded that Hai'l soil is a niche of diverse bacteria with a high interest in soil environment and ecosystems. Further studies are required for further classification of all identified bacteria and to define their specific role in the environment.
