“…Over one‐third of the total food produced (1.3 billion tons) in the world is lost due to spoilage, mismanagement, and faulty packaging. [ 121 ] Food quality and safety are essential to minimize food waste and food‐borne diseases, given the current global situation. Gases such as ammonia and ethylene,VOCs such as basic amines, and total volatile basic nitrogen (TVBN) compounds (e.g., trimethylamine (TMA)) are indicators used to assess food quality and safety.…”

Gas detection and monitoring are essential due to their direct impact on human health, environment, and ecosystem. Chemiresistive sensors are one of the most used classes of sensors for monitoring and measurement of gases thanks to their ease of fabrication, customizability, mechanical flexibility, and fast response time. While chemiresistive sensors can offer good sensitivity and selectivity to a particular gas in a controlled environment with known interferences, they may not be able to differentiate between various gases having similar physiochemical properties under uncontrolled conditions. To address this shortcoming of chemiresistive gas sensors, sensor arrays have been the subject of recent studies. Gas sensor arrays are a group of individual gas sensors that are arranged to simultaneously detect and differentiate multiple cross‐reactive gases. In this regard, various sensor array technologies have been developed to differentiate a given set of gases using multivariate algorithms. This review provides an insight into the different algorithms that are used to extract the data from the sensor arrays, highlighting the fabrication techniques used for developing the sensor array prototypes, and different applications in which these arrays are used.

Glaucium belongs to the Papaveraceae family. Glaucium is a genus of annual, biennial, and perennial herbaceous plants that thrive on salty soils and near the sea.Glaucium is represented by a total of 10 taxa in Iran. Sequence-related amplified polymorphism was used to estimate genetic diversity. A combination of morphological and genomic data was used to identify genetic diversity and species features in Glaucium species. In eight provinces, 65 people connected to five Glaucium were gathered. Through polymerase chain reaction (PCR) amplification of five Glaucium species, a total of 144 (Number of total loci) (NTL) DNA bands were obtained. These bands were created by combining 10 different selective primers. The total number of amplified fragments varied from seven to twenty-six. The expected unbiased heterozygozity (H) ranged from 0.19 (G. grandiflorum subsp. grandiflorum var. grandiflorum) to 0.33 (G. grandiflorum subsp. grandiflorum var. grandiflorum) (G. oxylobum var. oxylobum). The genetic similarities between five species range from 0.63 to 0.88. The findings of clustering revealed two large groupings. The SRAP (Sequence-related amplified polymorphism) markers study revealed that G. grandiflorum and G. oxylobum var. oxylobum had the least similarity. This investigation also discovered a substantial indication of distance isolation (Mantel test results). The current findings indicate that sequence-related amplified polymorphism can discover and understand genetic affinity in Glaucium species. The current findings have consequences for biodiversity and conservation efforts. Aside from that, the current findings may pave the way for identifying acceptable ecotypes for grazing and pasture uses in Iran.

The increase in dryland agriculture elicits the need to develop sustainable practices that improve crop yield and protect soil fertility. The use of biofertilisers adapted to nutrient deficient soils and arid climates would help achieve this. In this review, the use of plant growth-promoting bacteria is explored as a possible solution to the current state of dryland agriculture and climate change threats to agriculture. Plant microbe interactions form the basis of this review as evidence has shown that these interactions often exist to improve the health of plants. This is achieved by the production of important biochemicals and enzymes like indole acetic acid and amino cyclopropane-1-carboxylate deaminase while also actively protecting plants from pathogens including fungal pathogens. Research, therefore, has shown that these plant-growth promoting bacteria may be exploited and developed into biofertilisers. These biofertilisers are both economically and environmentally sustainable while improving soil quality and crop yield. The literature presented in this review is in context of the Namibian climate and soil profiles.
