“…Noteworthily, the previous studies have shown that the nitrogen fixation ability and the changes of nitrogen in plants are also affected by soil fertility [51,52], soil microorganisms [53,54] or metal elements [55]. We studied the change of elevated CO 2 content as the main factor but did not verify or discuss the influence of other factors on nitrogen metabolism of Masson pine under the same condition.…”

To explore the response of nitrogen metabolism in Masson pine (Pinus massoniana) to high CO2 concentrations, needles from one-year-old seedlings were used as materials to detect key enzyme activities, gene expression and different forms of nitrogen metabolites after CO2 stress for different durations (0 h, 6 h, 12 h, 24 h). The results show that elevated CO2 affected the efficiency of nitrogen metabolism in Masson pine needles, inhibiting the expression of key genes involved in nitrogen metabolism, including glutamate synthase (GOGAT), nitrite reductase (NiR), glutamine synthase (GS), nitrate reductase (NR) and glutamate dehydrogenase (GDH), and decreasing the activities of GOGAT, NiR, and GS. The decrease in enzyme activities and gene expression caused a decrease in different forms of nitrogen metabolites, including total nitrogen, ammonium, nitrite and specific amino acids. With prolonged stress, the nitrate content increased first and then decreased. In this study, the response pattern of nitrogen metabolism to CO2 stress in Masson pine needles was described, which may aid future research on nitrogen utilization in Masson pine.

“…in Medicago truncatula and Mimosa pudica (Benezech et al, 2020b;Moura et al, 2020). Fungal species such as Cladosporium cladosporioides, Fusarium moniliforme, Fusarium oxysporum, Fusarium solani, Macrophominia phaseolina, and Rhizoctonia solani are known plant pathogens (Walker et al, 2016;Batnini et al, 2020;Chen et al, 2020;Lakhran and Ahir, 2020;Poveda et al, 2020). However, non-pathogenic strains of the previously mentioned fungi with plant growth promoting effects have been isolated from leguminous root nodules of faba bean (Vicia faba) (Omar and Abd-Alla, 2000).…”

Rhizobia are bacteria that exhibit both endophytic and free-living lifestyles. Endophytic rhizobial strains are widely known to infect leguminous host plants, while some do infect non-legumes. Infection of leguminous roots often results in the formation of root nodules. Associations between rhizobia and host plants may result in beneficial or non-beneficial effects. Such effects are linked to various biochemical changes that have far-reaching implications on relationships between host plants and the dependent multitrophic biodiversity. This paper explores relationships that exist between rhizobia and various plant species. Emphasis is on nutritional and phytochemical changes that occur in rhizobial host plants, and how such changes affect diverse consumers at different trophic levels. The purpose of this paper is to bring into context various aspects of such interactions that could improve knowledge on the application of rhizobia in different fields. The relevance of rhizobia in sustainable food systems is addressed in context.

“…The results showed that addition of cyanobacteria significantly reduced Fusarium infection, enhanced POD and PPO expressions, and also increased SA, indole-3-Acetic levels, while decreased ABA content in infected plants showing that use of foliar treatment of these bacteria can improve plant growth, metabolic characteristics, and defence responses against Fusarium wilt [94]. Likewise, the activities of SOD, POD, and CAT antioxidants were documented higher in Medicago truncatula plants when treated with Sinorhizobium meliloti and Sinorhizobium medicae, and these bacterial treatments also increased sucrose content and reduced oxidative stress due to fungal pathogen F. oxysporum [95]. Thus, it is confirmed from various reported studies that the plant antioxidant system is activated under Fusarium attack and plays its vital part by detoxifying excess ROS production and improving plant growth and development.…”

Fusarium pathogens are causal agents of several crop diseases and produce harmful mycotoxins resulting in crop and yield reduction worldwide. Among crop diseases, Fusarium wilt, Fusarium head blight, and root light are mostly reported diseases in numerous vegetables, crops, and fruits and have posed pressure on current food production and safety. In addition, the production of mycotoxins further aggravates plant health and causes serious health risks in humans and animals through food chain contamination. Different management practices have been enlisted in this chapter to reduce or eradicate Fusarium wilt in different crops. Interestingly, various mechanisms developed by plants have also been highlighted to fight against Fusarium pathogens and limit the growth of mycotoxins. One of defence mechanisms is plant antioxidant mechanisms to reduce oxidative stress by increasing enzymatic and non-enzymatic antioxidants to maintain cellular homeostasis under Fusarium infection. The other defence response is through hormonal signalling to combat fungal pathogens. Different phytohormones such as salicylic acid, ethylene, jasmonate, abscisic acid, cytokinin, auxin, and other plant secondary metabolites play a crucial part in the reduction of Fusarium growth and inhibit mycotoxin production through defence-related genes. Further, the use of different pre-harvest and post-harvest strategies has been elucidated to enhance plant resistance and growth by decreasing fungal pathogenicity and virulence.
