Endogenous nitric oxide and hydrogen peroxide detection in indole-3-butyric acid-induced adventitious root formation in Camellia sinensis

Journal of Integrative Agriculture (2018)

Kang Wei Liyuan Wang Li Ruan Chengcai Zhang Liyun Wu

Nitric oxide (NO) and hydrogen peroxide (H2O2) are essential signaling molecules with key roles in auxin induced adventitious root formation in many plants. However, whether they are the sole determinants for adventitious root formation is worth further study. In this study, endogenous NO and H2O2 were monitored in tea cutting with or without indole-3-butyric acid (IBA) treatment by using the fluorescent probes diaminofluorescein diacetate (DAF-2DA) and 2',7'-dichlorodihydrofluorescein diacetate (DCF-DA), respectively. The overproduction of NO and H2O2 was detected in the rooting parts of tea cuttings treated with or without IBA. But little NO and H2O2 was detected before the initiation phase of tea cuttings even with IBA treatment indicating that they might be not directly induced by IBA. Further carbon and nitrogen analysis found that the overproduction of NO and H2O2 were coincident with the consumption of soluble sugars and the assimilation of nitrogen. These results suggest that rooting phases should be taken into consideration with the hypothesis that auxin induces adventitious root formation via NO- and H2O2-dependent pathways and sink establishment might be a prerequisite for NO and H2O2 mediated adventitious root formation.

Floral Transcriptome Sequencing for SSR Marker Development and Linkage Map Construction in the Tea Plant (Camellia sinensis)

PLoS ONE (2013)

Liqiang Tan Liyuan Wang Kang Wei Chengcai Zhang Liyun Wu

Despite the worldwide consumption and high economic importance of tea, the plant (Camellia sinensis) is not well studied in molecular biology. Under the few circumstances in which the plant is studied, C. sinensis flowers, which are important for reproduction and cross-breeding, receive less emphasis than investigation of its leaves or roots. Using high-throughput Illumina RNA sequencing, we analyzed a C. sinensis floral transcriptome, and 26.9 million clean reads were assembled into 75,531 unigenes averaging 402 bp. Among them, 50,792 (67.2%) unigenes were annotated with a BLAST search against the NCBI Non-Redundant (NR) database and 10,290 (16.67%) were detected that contained one or more simple sequence repeats (SSRs). From these SSR-containing sequences, 2,439 candidate SSR markers were developed and 720 were experimentally tested, validating 431 (59.9%) novel polymorphic SSR markers for C. sinensis. Then, a consensus SSR-based linkage map was constructed that covered 1,156.9 cM with 237 SSR markers distributed in 15 linkage groups. Both transcriptome information and the genetic map of C. sinensis presented here offer a valuable foundation for molecular biology investigations such as functional gene isolation, quantitative trait loci mapping, and marker-assisted selection breeding in this important species.

Effect of thermal treatments on volatile profiles and fatty acid composition in sweet corn (Zea mays L.)

Food Chemistry X (2023)

Bing Zhang Kun Li Hao Cheng Jianguang Hu Xitao Qi

This study analyzed the effects of thermal processing on volatiles and fatty acids in sweet corn. There were 27 volatiles measured in fresh samples, and 33, 21, and 19 volatiles identified in the steaming, blanching, and roasting groups, respectively. Relative odor activity values (ROAVs) showed that characteristic aroma-active volatiles of sweet corn after thermal treatments included: (E)-2-nonenal, 1-octen-3-ol, beta-myrcene, dimethyl trisulfide, 1-(4,5-dihydro-2-thiazolyl)-ethanone, and d-limonene. Thermal treatments significantly increased the unsaturated fatty acids (oleic acid and linolenic acid) of sweet corn by 110 to 183% compared to fresh samples. Meanwhile, many characteristic volatiles were found that derived from the oxidative cleavage of fatty acids. The sweet corn aroma obtained by steaming for 5 min was considered the closest to fresh corn. Our research provided insight into aroma composition of different thermally processed sweet corn and laid the foundation for further exploring the sources of aroma compounds in thermally processed sweet corn.

Study of Developmental Pattern of Tea Shoot Tenderness on the Base of Texture Analyser

Chaye kexue (2012)

Yan Huang Wei Kang Liyuan Wang Hao Cheng Wei He

Texture analyser was utilized to study shoot tenderness in tea cultivar Longjing 43 and Zhongcha 108.The evaluation method was established by taking maximum shearing force to determine shoot tenderness.Low maximum shearing force represents high shoot tenderness.The results showed that it is feasible to use texture analyser to determine shoot tenderness.There was a sharp decrease of shoot tenderness from the third to fifth node.Furthermore,the tenderness of the first and second nodes was relatively high.The shoot tenderness was correlated with maturity,spatial location,plucking time and variety.Pruning significantly increased the tenderness of the third and fourth nodes.A consistently changing pattern of tea shoot tenderness was found by texture analyser in this study,which provided a useful method to evaluate shoot tenderness and its keeping ability in tea plant.

Accumulation of catechins and expression of catechin synthetic genes in Camellia sinensis at different developmental stages

Botanical studies (2016)

Liqun Zhang Kang Wei Hao Cheng Liyuan Wang Chengcai Zhang

Catechins are the main polyphenol compounds in tea (Camellia sinensis). To understand the relationship between gene expression and product accumulation, the levels of catechins and relative expressions of key genes in tea leaves of different developmental stages were analyzed. The amounts of catechins differed significantly in leaves of different stages, except for gallocatechin gallate. Close correlations between the expression of synthesis genes and the accumulation of catechins were identified. Correlation analysis showed that the expressions of chalcone synthase 1, chalcone synthase 3, anthocyanidin reductase 1, anthocyanidin reductase 2 and leucoanthocyanidin reductase genes were significantly and positively correlated with total catechin contents, suggesting their expression may largely affect total catechin accumulation. Anthocyanidin synthase was significantly correlated with catechin. While both ANRs and LAR were significantly and positively correlated with the contents of (−)-epigallocatechin gallate and (−)-epicatechin gallate. Our results suggest synergistic changes between the expression of synthetic genes and the accumulation of catechins. Based on our findings, anthocyanidin synthase may regulate earlier steps in the conversion of catechin, while the anthocyanidin reductase and leucoanthocyanidin reductase genes may both play important roles in the biosynthesis of galloylated catechins.
