“…However, some other studies on saline soil found that the effect of salt washing by irrigation and drainage of rice cultivation is very limited (Huang et al, 2016). The inconsistent result might attribute to different cultivation years, soil texture and soil management (Joseph et al, 2016; Moharana et al, 2018). At present, studies on soil properties of rice cultivation mainly focus on topsoil.…”

Rice cultivation has been found to be an effective and feasible approach for improving saline soils and increasing food production. Most studies on the improvement of rice cultivation on saline soil have focused on the several individual soil properties in the topsoil, and we know little about the importance of rice cultivation for improving multifunctionality in coastal saline soils. We investigated basic soil properties (soil physical sand content, soil physical clay content, pH, EC, soil organic carbon, total nitrogen, alkaline hydrolysis nitrogen, available potassium, available phosphorus), enzyme activities (urease, catalase, protease) and soil multifunctionality (SMF) in 0–20 cm, 20–40 cm, 40–60 cm, 60–80 cm and 80–100 cm soil layers with rice cultivated for 0 (tidal flat; CK), 20 (R20), 44 (R44) and 70 years (R70). We found that soil EC was alleviated markedly in the first 20 years after rice cultivation. Soil physical sand content, pH, EC and available potassium (AK) decreased while total nitrogen (TN), alkaline hydrolysis nitrogen (AN), urease (URE), catalase (CAT) activities and SMF increased with the increase in rice cultivation years. The highest soil total organic carbon (SOC) was shown in R44. Soil pH, EC, AK and physical sand content increased while SOC, TN, AN, enzyme activities decreased with the increase in soil depth. Redundancy (RDA) analysis showed soil physicochemical properties explained 97.53% of the variation in soil enzyme activities. Soil CAT, URE and protease (PRO) had a positive correlation with soil physical clay content, SOC, TN, AN and AP while negatively correlated with pH and AK. The increased SOC and clay content by rice cultivation might be the main reasons stimulating soil enzyme activities. In summary, long‐term rice cultivation could alleviate soil salinity, increased SMF down to 1 m, implying that rice cultivation effectively improved coastal saline soil, and the improvement could last for 70 years.

Biotechnology methods particularly tissue culture techniques offer new approaches for the in vitro production of valuable plant nutraceuticals. The large-scale production of secondary metabolites in a year-round system without seasonal constraints is one of the advantages of plant tissue culture techniques. Furthermore, enhancement of in vitro nutraceuticals production can be realized by a selection of high-producing cell lines and medium optimization. In this respect, several techniques have been adopted to improve the production of plant-derived nutraceuticals such as mutation, elicitation, precursor feeding, genetic transformation and metabolic engineering. In vitro mutagenesis of cultured cells and tissues by irradiation or chemical mutagens represents a feasible method for the improvement of nutraceuticals production. Likewise, transformation is another strategy that is used to enhance nutraceuticals in plant cells or organ tissues. At this point, hairy root culture induced by Agrobacterium rhizogenes is the most promising transformation technique used for in vitro production of valuable plant compounds. The benefits of hairy roots are high metabolite productivity, high growth rates and inherent genetic stability. On the other hand, due to its effectiveness and practical feasibility, elicitation is considered the most applied strategy for enhancing the production of desired compounds in plant biotechnology. Biotic (biological origin) and abiotic (non-biological origin) elicitors are used to increase the production of plant metabolites by different effects on the cellular processes in the plant system. Furthermore, bioreactors developed for in vitro industrial-scale production of desired compounds can be used for continuous and scaling-up plant nutraceuticals production. This article discusses different aspects of biotechnology used for the selection and enhancement production of nutraceuticals from plant cultures grown cells, in vitro.
