“…Presently, there are more than 100 extant varieties of soybean cultivated in India. Nevertheless, the success of these high yielding and improved varieties largely relies on the availability of quality seed with greater genetic purity standards [ 29 , 30 ]. The genetic purity of commercial seed lots is traditionally assayed by performing Grow Out Tests (GOT) based on morphological characters that is not only time taking and quite laborious, but also highly environmental responsive [ 24 ].…”

Background The genetic base of soybean cultivars in India has been reported to be extremely narrow, due to repeated use of few selected and elite genotypes as parents in the breeding programmes. This ultimately led to the reduction of genetic variability among existing soybean cultivars and stagnation in crop yield. Thus in order to enhance production and productivity of soybean, broadening of genetic base and exploring untapped valuable genetic diversity has become quite indispensable. This could be successfully accomplished through molecular characterization of soybean genotypes using various DNA based markers. Hence, an attempt was made to study the molecular divergence and relatedness among 29 genotypes of soybean using SSR markers. Methods and results A total of 35 SSR primers were deployed to study the genetic divergence among 29 genotypes of soybean. Among them, 14 primer pairs were found to be polymorphic producing a total of 34 polymorphic alleles; and the allele number for each locus ranged from two to four with an average of 2.43 alleles per primer pair. Polymorphic information content (PIC) values of SSRs ranged from 0.064 to 0.689 with an average of 0.331. The dendrogram constructed based on dissimilarity indices clustered the 29 genotypes into two major groups and four sub-groups. Similarly, principal coordinate analysis grouped the genotypes into four major groups that exactly corresponded to the clustering of genotypes among four sub-groups of dendrogram. Besides, the study has reported eight unique and two rare alleles that could be potentially utilized for genetic purity analysis and cultivar identification in soybean. Conclusion In the present investigation, two major clusters were reported and grouping of large number of genotypes in each cluster indicated high degree of genetic resemblance and narrow genetic base among the genotypes used in the study. With respect to the primers used in the study, the values of PIC and other related parameters revealed that the selected SSR markers are moderately informative and could be potentially utilized for diversity analysis of soybean. The clustering pattern of dendrogram constructed based on SSR loci profile displayed good agreement with the cultivar’s pedigree information. High level of genetic similarity observed among the genotypes from the present study necessitates the inclusion of wild relatives, land races and traditional cultivars in future soybean breeding programmes to widen the crop gene pool. Thus, hybridization among diverse gene pool could result in more heterotic combinations ultimately enhancing genetic gain, crop yield and resistance to various stress factors.

“…It has been reported that nitrogen‐doped CDs can produce reactive nitrogen species. Nitrogen groups can easily convert to toxic nitric oxide (NOx), which can cause oxidative stress to cells [64–68] . This leads to higher cytotoxicity of nitrogen‐doped CDs than other CDs.…”

Carbon dots (CDs) are fascinating nanomaterials with technologically relevant properties; however, the effects of heteroatom doping on several properties of CDs have not been studied. In this work, a facile method for the synthesis and heteroatom doping of carbon dots from table sugar was developed using nitric acid, phosphoric acid, and sulfuric acid as simultaneous catalysts and dopants. The optical properties, phenolic content, antioxidant activity, photostability, and cytotoxicity of the CDs were measured and compared. Lascorbic acid, a well-known antioxidant, and avobenzone and oxybenzone, common UV absorbers in sunscreens, were used for comparison. Interestingly, heteroatom doping has adverse effects on several properties of the CDs as the undoped CDs yielded the highest UV-vis absorption, phenolic content, antioxidant activity, photostability, and biocompatibility. Only fluorescence quantum yields were improved by heteroatom doping. These findings will be crucial for choosing precursors for the synthesis of CDs because heteroatoms inherently present in precursors can have negative effects on the properties of the resulting CDs.

“…The reactivation of metabolism following seed imbibition may provide an important source of ROS. For instance, H 2 O 2 production has been observed during the transition from a dormant state to a metabolically active state in jasmine rice garden pea, sunflower seeds, soybean, maize, wheat, and radish [192]. The production of ROS by germinating seeds has typically been regarded as a cause of stress that may affect the success of germination, and antioxidant compounds and enzymes have been widely considered to be of particular importance to the completion of germination [181].…”

The growing demand for food represents an enormous problem for agri-food industries. It is driven by global population growth on the one hand and constrained by greenhouse gas reduction targets on the other. Accordingly, the implementation of new energy-efficient, low-carbon, and biodiversitypreserving technologies has become an absolute priority. In this work, the basic processes and requirements for the successful implementation of low-temperature atmospheric-pressure plasmas generated in air are considered in the various steps of the agricultural food production chain. This paper briefly reviews the history of plasma science in agriculture as well as discusses the pros and cons of low-pressure plasma versus atmospheric-pressure plasma. Particular attention is focused on plasmas generated using low-cost gases, such as synthetic or ambient air. The influence of various plasma components is discussed. These include electromagnetic fields (specifically ultraviolet-visible near-infrared radiation) and reactive oxygen and nitrogen species in the typical pre-harvest and post-harvest processing in the agri-food value chain. Finally, state-of-the-art cold air plasma generation and its potential deployment at the laboratory scale and under real farming conditions for industrial-scale production are examined.
