Special Issue Information

Dear Colleagues,

Global climate change, shifting land-use, and the intensification of agriculture are increasing crop stress caused by drought, salinity, herbivores, and pathogens. Emerging social and regulatory factors have motivated interest in the development of sustainable agriculture, which can be obtained by the implementation of green technologies with the capacity to protect crops from exposure to potential damage caused by various abiotic and biotic stresses. For instance, this can be achieved by breeding plant genotypes with specific traits that can survive disease or terrible environmental conditions as well as applying soil amendments such as compost and seed meal to limit the proliferation of soil-borne disease and changing nutrient cycling in agro-ecosystems. Additionally, plant-associated microbial niches, especially rhizosphere microbiome possess members, that are able to stimulate plant hormone and immune responses, increase micronutrient availability and shield plants from diseases by producing secondary metabolites with antibiotic or antifungal properties.

Overall, the scope of this research welcomes submissions that advance recent biotechnological applications in the field of sustainable agriculture as well as the mechanisms behind them.

Suggested topics include but are not limit to:

  1. The applications and the mechanisms of beneficial micro-organisms (bacterial, fungal, algal, or integrated approaches) to ameliorate the abiotic and biotic sources of stress on plants.
  2. Molecular approaches such as metagenomics and metaproteomics to understand interactions during agricultural management.
  3. Genetic plant studies on stress resistance/tolerance and the interactions between plant host and its associated rhizosphere microbiome.
  4. The alteration of the soil microbial community and nutrient bioavailability upon the application of soil amendments.

Fusarium oxysporum f. sp. cubense (Foc) causes banana Fusarium wilt disease, which is a destructive soil-borne disease. Many plants can recruit rhizosphere microorganisms using their root exudates, thereby shaping the rhizosphere microbiome to resist pathogen infection. Therefore, this study was conducted to explore the role of root exudates in the process of biocontrol strain colonization and resistance to pathogens. In this study, the banana root exudates used as chemoattractants were obtained by hydroponics. Bacillus velezensis strain LG14-3 was isolated from the infected area of the root system of banana and showed significant chemotaxis to banana root exudates and strong inhibition of Fusarium oxysporum f. sp. cubense. Further analysis found that LG14-3 showed chemotaxis toward the components of banana root exudates, such as citric acid, succinic acid, glycine, D-galactose and D-maltose, and glycine and citric acid, which resulted in more significant chemotaxis of LG14-3. Moreover, banana root exudates enhanced the swarming motility and biofilm formation of LG14-3. Pot experiments showed that glycine and citric acid enhanced the colonization ability of Bacillus velezensis LG14-3 in the banana rhizosphere and reduced the disease severity index of banana fusarium wilt. Glycine and citric acid enhanced the growth-promoting ability of LG14-3 under pathogen stress. Our results showed that the addition of chemotactic substances enhanced the biocontrol potential of Bacillus velezensis LG14-3 to prevent banana Fusarium wilt. Full article

The potato (Solanum tuberosum L.) is an important cash crop with a complex genome and with features of aneuploidy with a high level of heterozygosity. It is a prerequisite for potato breeding to have knowledge of genetic diversity and population structure. To understand the genetic characteristics of potato cultivars in Pakistan, 25 potato varieties were characterized with simple sequence repeat (SSR) markers to distinguish closely related varieties. In total, 214 alleles were amplified with 35 SSR markers exhibiting 89.2% polymorphism. The maximum number of alleles and polymorphic alleles per locus were 20 and 14 for the markers S25 and S174, respectively. The polymorphic information content (PIC) extended from 0.00–0.87. The size of the amplified PCR product ranged between (30–1000 bp). A cluster analysis divided the 25 varieties into three clusters: cluster I revealed the most diversity, followed by cluster II with 11 varieties and cluster III with 13 varieties. Nei’s genetic diversity and minimum spanning network (MSN) depicted the Mozika variety as the most diverse compared to the rest of the varieties. Nei’s coefficient was found to vary from 0.53 to 0.95. Out of the 25 studied varieties, 16 were uniquely identified by 29 polymorphic SSR bands of different sizes with a maximum size amplified by S4026/4027 (800bp) and a minimum by S170 (90bp). The genetic diversity and varietal identification determined in the present study has molecular and breeding-related significance with respect to the utilization and protection of intellectual property rights of potato cultivars for sustainable potato production in Pakistan.
