BACKGROUND This study aimed to evaluate the possibility of cotton waste enrichment with glycine betaine (GB) for production of two strains (P9, P10) of king oyster (Pleurotus eryngii). Cotton waste was used as (100%) control (T0 = cotton waste) and augmented with various combinations of GB, (T1 = 2 mmol L−1, T2 = 4 mmol L−1, T3 = 6 mmol L−1, T4 = 8 mmol L−1 and T5 = 10 mmol L−1). The response of king oyster to GB was evaluated by earliness, yield, biological efficiency (BE), minerals (nitrogen, phosphorus, potassium, zinc (Zn), copper (Cu), magnesium (Mg), manganese (Mn), iron (Fe), sodium (Na), calcium (Ca)), total sugars, total soluble solids, reducing sugars, non‐reducing sugars, ascorbic acid, proximate (crude protein, carbohydrates, crude fibers, ash, fats) content of fruiting body and Fourier‐transform infrared (FTIR) spectroscopy analysis compared with the control substrate (cotton waste). RESULTS The earliness, yield, and BE were higher as compared to control substrate and increased with an augmentation in the concentration of GB within the cotton waste. Two strains showed (on dry weight basis) 33.9–54.9 mg g−1 nitrogen, 6.8–12.5 mg g−1 phosphorus, 16.9–25.1 mg g−1 potassium, 40.5–64.2 mg kg−1 Zn, 17.1–37.3 mg kg−1 Cu, 1174–1325 mg kg−1 Mg, 20.1–29.1 mg kg−1 Mn, 129–265 mg kg−1 Fe, 779–835 mg kg−1 Ca), 6.3%–11.3% total sugars, 7.3–14.9 °Brix total soluble solids, 2.1–7.3% reducing sugars, 10.4–18.1% crude protein, 3.6–4.4% crude fiber and 5.6–16.7 mg (100 g)‐1 on various concentration of GB enrich cotton waste. Cotton waste enriched with GB significantly affected nutritional profile of king oyster mushroom. CONCLUSION The results revealed that GB enriched cotton waste can be used as an innovative substrate to enhance the yield and quality of king oyster mushroom. © 2019 Society of Chemical Industry

“…Therefore, based on other studies (Gibon and Larher, 1997;Korkmaz et al, 2012), we concluded that GB is not an osmolyte, as reported by Asma et al (2006), who observed that the foliar application of GB to corn did not have the expected effect. Although it has been reported that GB acts as an osmoprotectant in some plant species, it is important to mention that these studies have only been performed in vitro (Saini et al, 2012).…”

Water stress is the main factor responsible for decreased productivity, which affects the growth and development of crops. Plants respond to stress by accumulating compatible solutes, which have a key role in osmotic adjustment, thereby resulting in osmoprotection of the plants. The loss of water can increase the concentration of compatible osmolytes and molecules that regulate the plant metabolism. These solutes can be metabolized as sugars (sucrose, fructose, trehalosa), amino acids (proline), an amphoteric quaternary amine (glycine betaine), and other low-molecular-weight metabolites. However, among all these compatible solutes, proline and glycine betaine occur the most. Proline is an amino acid that can accumulate in low concentrations under optimal conditions; however, stress conditions contribute to its increased content. Few data are available regarding the levels of endogenous glycine betaine on Solanaceae, which is considered a nonaccumulator under water deficit conditions. The objective of this research was to evaluate the role of compatible osmolytes, glycine betaine and proline, in Capsicum sp. plants under different water deficit conditions. In this study, the presence of endogenous levels of proline and glycine betaine in two species of pepper (Capsicum chinense var. Genesis and Rex and Capsicum annuum var. Padron) were found. The concentration levels of proline were 362, 292, and 246 mmol · g L1 DW for Genesis, Rex and Padron respectively, and irrigation conditions (rehydration) of proline levels increased to 381, 395, and 383 mmol · g L1 DW at 21 days. However, glycine betaine levels were 30-70 mmol · g L1 DW. The relative water content, electrolyte leakage, and soil water potential were also analyzed; therefore, the information suggests that proline contributes better to tolerance to water deficit in the genus Capsicum after 14 days of water deficit treatment. It seems that the contribution of glycine betaine is less effective than that of proline; therefore, it does not have an important role in osmotic adjustment.

Saini et al [24] reported the stimulatory effect of 125-1,000 mg/l GB on growth, shoot number and shoot multiplication rate in two commercially important UPASI (U-9 and U-10) cultivars of tea (Camellia sinensis L.

Despite being protected, the number of plants that belong to Sideritis genus has decreased in the last years due to the urbanization of its natural habitat. Sideritis raeseri Boiss and Heldr. subsp. raeseri known as mountain tea of Parnassus or Velouchi is a valuable genetic resource of the Greek flora because of its special characteristics, so, the development of a micropropagation protocol is crucial to its conservation and use in breeding programs. The objectives of the study were to evaluate the effects of glycine betaine (GB), polyvinylpyrrolidone (PVP-10) and D-mannitol applied in different concentrations in combination with auxins [α-naphthaleneacetic acid (NAA), indole-3-butyric acid (IBA)] on shoot proliferation and rooting of shoot-tip explants of the studied species. Better shoot proliferation results were obtained in the following two combination treatments: (1) 100 mg/l GB + 0.5 mg/l NAA (5.5 shoots/explant 2.34 cm long, 75% shoot multiplication), and (2) 2.5 g/l D-mannitol + 3 mg/l IBA (2.92 shoot/explant 83.33% shoot multiplication percentage). In relation to rooting, better results were performed only with PVP at 0.5 g/l applied simultaneously with 0.5 mg/l NAA (12 roots/rooted microcutting, 1.47 cm root length, 90% rooting). The ex vitro survival percentage of rooted microcuttings derived from all 5 experiments was ranged between 68% and 93%.
