“…Notably, chitosan is a low-cost biopolymer mainly derived from the waste exoskeletons of edible crustaceans (Hadwiger, 2013). Moreover, chitosan is well documented as an effective "plant defense booster'' that can trigger various physiological and biochemical reactions, in which the stimulation of phytoalexin biosynthesis is flagged as a characteristic event (Katiyar et al, 2015). More importantly, chitosan is a natural biopolymer with excellent biocompatibility and biodegradability (Sathiyabama et al, 2016).…”

Elicitation for phytochemical enhancement via cost-effective elicitors can overcome the limitation of commercial application faced by plant cell and organ culture technology. Chitosan is a natural, low-cost, and nontoxic elicitor that can trigger plant defense responses with the concomitant enhancement in phytochemical biosynthesis. In this work, the elicitation of Isatis tinctoria L. hairy root cultures by chitosan was conducted to enhance the production of pharmacologically active flavonoids. In comparison with control (2.31 ± 0.29 mg/g DW), a 7.08-fold enhancement of total flavonoids (16.35 ± 0.88 mg/g DW) was achieved in 24 day-old I. tinctoria hairy root cultures elicited by 150 mg/L chitosan for 36 h. Interestingly, the multiple hydroxyl-substituted flavonoids (rutin, quercetin, isorhamnetin, and isoliquiritigenin) were noticed to increase significantly in chitosan-elicited I. tinctoria hairy root cultures. Moreover, the transcription of associated genes involved in flavonoid biosynthesis pathway was significantly up-regulated underlying chitosan elicitation, among which chalcone synthase and flavonoid 3′-hydroxylase might play an important role in flavonoid enhancement. Additionally, extracts from chitosan-elicited I. tinctoria hairy root cultures exhibited higher antioxidant activities with lower IC 50 values as compared with control. Overall, a cost-effective strategy via the simple chitosan elicitation is provided here to enhance the production of high-added value flavonoids in I. tinctoria hairy root cultures, which paves the way toward the successful commercialization of this in vitro culture system in the future.

“…Therefore, the shrimp extract is a low-cost and environmentally-friendly resource. The chitosan compounds deacetylated from chitin that are extracted from shrimp are effective in promoting seed germination, and root and shoot growth, and can induce resistance to abiotic stresses, as well as acting as biopesticides [14,22,[49][50][51]. Therefore, the positive effect of L1 may be partly due to the presence of chitosan.…”

Abstract:Organic fertilizers are generally thought to be an effective way to sustain soil fertility and plant growth. To promote the productivity of chrysanthemum, five sources of liquid organic fertilizers (L1-L5), as well as a chemical fertilizer, were applied at an early stage of the growth cycle to investigate their effects on plant growth. In the short-term pot experiment, the liquid organic fertilizers significantly promoted root and aboveground growth by 10.2-77.8% and 10.7-33.3%, respectively, compared with the chemical fertilizer. The order of growth promotion was: L1 (shrimp extracts) > L2 (plant decomposition) > L4 (seaweed extracts)/L5 (fish extracts) > L3 (vermicompost). Morphological and chemical analyses indicated that, compared with other organic fertilizers, the treatment with shrimp extract (L1) produced the greatest increases in root dry weight, total length, surface area, volume, tips, and thick root length, respectively. Furthermore, the shrimp extract treatment significantly increased the nutrient contents and altered the soil's functional microbial community at the rhizospheric level compared with the chemical fertilizer treatment. Thus, the shrimp extract liquid organic fertilizer could be part of an effective alternative to chemical fertilization during the early stage of chrysanthemum growth.

“…When chitosan with elevated ozone were combined, the photosynthesis increased due to the sensitive response of rice to chitosan, while ozone penetrated to stomata and created reactive oxygen species (ROS), further affecting photosynthetic cells, resulting in the cellular component injury, like proteins, nucleic acids and membrane lipids (Katiyar et al, 2015). Moreover, ozone could reduce stomatal conductance, inhibit carbon dioxide fixation in carboxylation process and reduce the quantities and efficiency of rubisco enzymes in Calvin cycle (Ainsworth et al, 2012).…”

This research aimed to study the effects of chitosan on physiology, photosynthesis and biomass of rice cultivar RD47 under elevated ozone. Rice samples were grown at indoor climate controlled chambers, allowing the inlet air to pass through charcoal filters. For combined effects of chitosan and ozone, rice was soaked and sprayed with chitosan 0.05% (W/V) under elevated ozone concentration at 40 ppb (Chi+EO 3 40) and 70 ppb (Chi+EO 3 70). Control groups (CF) with no additional ozone were also studied. Samples were analyzed weekly for tiller number per plants, leaf area, leaf chlorophyll, photosynthesis, shoot biomass, root biomass and total biomass. The results obviously showed that ozone at the concentration of both 40 and 70 ppb caused negative effects on rice physiology, photosynthesis and biomass. The 70 ppb concentration, particularly, caused sever damage. Whilst soaking and spraying with chitosan could significantly reduce the harmful effects of ozone compared with the control group. For the samples soaked and sprayed with chitosan under elevated ozone for 21 days, Chi+EO 3 40 and Chi+EO 3 70 significantly performed more photosynthesis and contained more leaf chlorophyll than EO 3 40 and EO 3 70, respectively (p ≤ 0.05). In addition, chitosan could reduce the ozone negative effects and increased higher physiology and photosynthesis rate. However, there was no significant difference in biomass compared with the control group. Even through, ozone has been gradually increasing which made plants at risk, chitosan treatment could significantly ameliorate the effect of ozone and serve as a plant growth promoter with no harmful to human being.
