“…Starch phosphorylase (STP) activity was measured according to the Wang et al (2019) method. To extract the enzyme, 1 g of fresh shoot was added to 2 ml of extraction buffer (precooled to 4°C), which contained 5 mmol L −1 MgCl 2 , 1 mmol L −1 EDTA, 2% PVP, 0.1% BSA (bovine serum albumin), and 5 mmol L −1 DTT, and the mixture was homogenized for 1 min.…”

“…Li et al (2019b) considered lignification a typical senescence characteristic in bamboo shoots during storage. Accumulated evidence demonstrates that PAL and POD have fundamental roles in lignification (Yang et al, 2010;Luo et al, 2012b;Wang et al, 2019). The lignification of plants involves the polymerization of monolignols primarily derived from the phenylpropanoid pathway.…”

“…The optimum temperature and packaging conditions for bamboo shoot storage are recommended at 1°C for semipermeable materials, which can extend the shelf life beyond 28 d (Kleinhenz and Midmore, 2002). Moreover, nitric oxide (NO) and gamma irradiation techniques have been applied to the postharvest storage of fresh shoots, achieving some good results (Yang et al, 2010;Wang et al, 2019).…”

The mechanisms for physiological senescence in bamboo shoots after harvest remain unclear. This study investigated physiological changes in Fargesia yunnanensis shoots during storage at different temperatures. The relationship between morphological and physiological changes in bamboo shoots during storage was also analyzed. The results show that cold storage can reduce weight loss, browning, respiration rates, and sugar degradation in bamboo shoots; decrease related enzymatic activities; and inhibit the increase in lignin and cellulose content. The quality of bamboo shoots declines more during the first 3d after harvesting than it does during subsequent periods. The increase in the degree of lignification and fibrosis is the main reason for senescence and for the decline in quality of bamboo shoots after harvest. The bamboo shoots under RT conditions began browning during the third 3d of storage, with a browning rate of 688gkg−1 even in the upper parts; the increase in shoot browning degrees significantly decreased the quality. Low temperatures had better inhibitory effects on browning than they did on lignification and fibrosis. Nonstructural carbohydrates in bamboo shoots are degraded and flow into sheath and shoot respiration, phenols, and shoot fibrosis and lignification at room temperature, but only flow into sheath respiration, shoot fibrosis, and lignification at cold temperature. Soluble protein and free amino acids are primarily distributed into shoot and sheath respiration and into phenols at room temperature, but that process is well inhibited at cold temperature. Bamboo shoots, once removed from cold storage, should be consumed rapidly because enzyme activity recovers quickly. This research provides new theoretical information on the preservation of bamboo shoots.

“…Despite the fact that there are many reports on the application of gamma irradiation on the onion commercial quality traits, however, the effect of gamma irradiation on PAL, POD and protein content has not been investigated. While the germicidal impact of gamma irradiation in more than 70 crops and in many countries has been widely studied for disinfection (Steele 2000;Jeong et al 2016;Jeong et al 2017;Wang et al 2019). The present study aimed to evaluate: 1) the effects of different doses of gamma radiation on POD, protein content, dry matter and phenylalanine ammonia lyase (PAL) during storage life of four onion genotypes, and 2) the expression of PAL gene in the best interaction of gamma irradiation dose and onion genotype treatment.…”

The present study aimed to evaluate the effects of different doses of gamma radiation on some physiological characters of onion genotypes and the expression of PAL gene in the best interaction of gamma irradiation dose and onion genotype treatment. To this aim, four onion genotypes (White-Qom, White-Neyshabour, Red-Ridge-Lump, and Red-Ray-Corrugated) irradiated at 0, 30, 60, 90, 120, and 150 Gy. After four months of storage (at 10-15 °C and 70% relative humidity), the effects of gamma rays on the dry matter (DM), protein content, phenylalanine ammonia lyase (PAL) and peroxidase (POD) were investigated. In addition, the expression of PAL gene in the best interaction of gamma irradiation dose and onion genotype treatment was assessed. The result indicated that POD activity was increased by most of the gamma irradiation levels; however, the protein content and PAL activity were decreased. Moreover, dry matter content was found to be highly genotype-dependent. A linear regression (R 2 = 0.82) between PAL activity and gamma irradiation levels, was observed. PAL activity decreased with increasing in gamma irradiation level, while the expression rate of PAL gene was not significantly changed between irradiated and non-irradiated control, indicating that the radiation might not have direct effects on the gene regulatory elements. These results suggest that gamma irradiation could reduce the PAL activity possibly by controlling abiotic stress sources such as fungal and bacterial stresses.
