“…The ability of AMF to improve plant nutrition, promote growth and enhance host plant resistance has remarkable effects, in tea plant as well as in others (Shao et al, 2018). Under natural and cultivated conditions, a highly diverse array of AMF is ubiquitous in root systems of tea bushes (Nepolean et al, 2012;Shao et al, 2018;Wu et al, 2019;Singh et al, 2010). The mainly AMF species forming symbiosis with tea roots are Acaulospora, Claroideoglomus, Gigaspora, Glomus and Scutellospora (Singh et al, 2008;Wu et al, 2019).…”

A pot experiment was carried out to evaluate the response of leaf antioxidant enzyme systems to inoculation with arbuscular mycorrhizal fungus (AMF) Clariodeoglomus etunicatum in tea (Camellia sinensis cv. ‘Fuding Dabaicha’) seedlings under drought stress (DS). Root AMF colonization was significantly decreased after an eight-week soil drought treatment. Plant growth performance (plant height, stem diameter, leaf number and root biomass), leaf relative water content, and leaf water potential were notably decreased under DS conditions, whereas these variables exhibited significantly higher responses in mycorrhizal seedlings than in non-mycorrhizal seedlings. The DS treatment markedly increased leaf superoxide anion concentration but did not affect malondialdehyde content, whereas both were reasonably decreased by AMF colonization regardless of water status. The seedlings colonized by AMF showed substantially higher antioxidant enzyme activities including superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase, and ascorbate peroxidase than the non-AMF colonized seedlings under both well-watered and DS conditions. DS markedly upregulated the relative expression of CsSOD in both AMF and non-AMF seedlings and the relative expression of CsCAT in AMF seedlings. Meanwhile, AMF-colonized seedlings represent markedly higher relative expressions of CsSOD and CsCAT than non-AMF seedlings, irrespective of water status. It concludes that mycorrhizal tea plants had higher antioxidant enzyme activity and corresponding gene expression under DS, indicating a stronger ability to alleviate the oxidative damage of drought.

“…Similarly, previous studies have shown that PGPR application causes a significant increase in the growth and yield of young tea bushes (Sharma et al, 2002;Chakraborty et al, 2006;Saravanakumar et al, 2007;Çakmakçı et al, 2014), and help in the reduction of the use of chemicals, N and P fertilizers in tea plantations (Chakraborty et al, 2009;Saikia et al, 2011;Princy et al, 2015). Although beneficial bacteria can reduce excessive use of chemical fertilizers without compromising plant growth and productivity, scientific knowledge on regarding the further development, improvement and use of such biofertilizer technology for a perennial crop such as tea is limited to a few studies (Nepolean et al, 2012;Chakraborty et al, 2012;Tennakoon et al, 2019). However, in processes combining indigenous beneficial PGPR with ¾ of the recommended N and P fertilizers (Saikia et al, 2011), or with 50% of synthetic fertilizers (Princy et al, 2015), a significantly sustainable higher yield was observed in tea compared to the recommended chemical fertilizer alone.…”

Bu araştırma mineral gübre, ticari mikrobiyal gübre ve azot fikseri, fosfat çözücü ve ACC deaminaze aktivitesine sahip bakteri esaslı üçlü kombinasyonlar halinde uygulanan üç farklı mikrobiyal gübre formülasyonunun (BF9: Bacillus megaterium 47/9 + Paenibacillus macquariensis RC696 + Pseudomonas fluorescens 9/7; BF10: Bacillus megaterium RC665 + Paenibacillus macquariensis RC382 + Pseudomonas fluorescens 9/7; BF11: Bacillus simplex RC64 + Pseudomonas putida 3/10 + Burkholderia pyrrocinia RC134) asidik tarla koşullarında üç yıllık sürede çay gelişim ve enzim aktiviteleri üzerine etkisinin belirlenmesi amacıyla yürütülmüştür. Deneme tesadüf bloklarında altı uygulama ve dört tekerrürlü (her bir tekerrürde beş çay öbeği) olarak kurulmuştur. Uygulanan bakteri formülasyonları yaprak alanı, yeşil yaprak verimi, klorofil içeriği ve bitki gelişimini teşvik etmiştir. Ayrıca, bakteri formülasyonu aşılamaları yaprakta; glutatyon redüktaz (GR), glutatyon S-transferaz (GST), glukoz 6-fosfat dehidrogenaz (G6PD), 6-fosfoglukonat dehidrogenaz (6PGD), polifenol oksidaz (PPO), peroksidaz (POD), 5-dehidroksişikimat redüktaz (DHSK) ve alkol dehidrogenaz (ADH), enzim aktivitelerini değiştirebilmiştir. Seçilen etkin, aside toleranslı ve çoklu özelliklere sahip bakteri esaslı biyoformülasyonlar, strese karşı bitki toleransı ve adaptasyonunu artırabilir, çay işleme teknolojisinde önemli bir rol oynayabilir ve çay ürünlerinin kalite konseptine katkıda bulunabilir. Bu çalışma, bu yerli faydalı rizobakteri izolatlarının, çay mahsulünün büyümesini teşvik etmek için mikrobiyal aşılama veya biyogübre olarak kullanılma potansiyeline sahip olduğunu ve sürdürülebilir çay yetiştiriciliği için umut verici olduğunu göstermektedir.

Understanding Camellia sinensis using Omics Technologies along with Endophytic Bacteria and Environmental Roles on Metabolism: A Review

et al. 2019

Camellia sinensis is the most consumed beverage worldwide. It contains a wide variety of secondary metabolites, such as alkaloids, saponins, tannins, catechins, and polyphenols, generated through a condensation reaction of cinnamic acid with three malonyl-CoA groups. In addition to the metabolic processes occurring within this plant, there are also some plant-associated bacterial endophytes. These bacteria reside in the living tissues of the host plants without causing any harmful effect to them, thereby stimulating secondary metabolite production with a diverse range of biological effects. Omics technologies reveal understanding of the biological phenomena of transcriptomics, proteomics, and metabolomics. In this sense, the present review aims to provide a comprehensive review of various methods used to identify distinct plant compounds, namely transcriptomic, proteomic, and metabolomic analysis. The role of endophytic bacteria in C. sinensis metabolism, and C. sinensis antioxidant and antimicrobial effects, are also carefully highlighted.
