ISSR Analysis of Genetic Diversity of Hovenia acerba from Fujian HUANG Wen, LI A-chi, HU Ying-ping, YANG Zhi-jian, MING Yan-lin, CHEN Hui 2019, 48(04): 314-320.  DOI: 10.3969/j.issn.1009-7791.2019.04.002 Abstract ( )   PDF (4177KB) ( )   In this study, ISSR molecular marker techniques were used to study genetic diversity and the genetic relationship of 35 Hovenia acerba germplasms from 12 provenances in Fujian. The reaction system of ISSR for analyzing the genetic diversity of H. acerba was established and optimized. The best one was shown as follows: total reaction volume 25 μL, 10×Ex Taq Buffer (Mg2+ plus) 2.5 μL, dNTP Mixture 375 μmol·L-1, primer 0.4 μmol·L-1, DNA template 75 ng, Ex Taq enzyme 1 U, ddH2O 14.55 μL. Procedures: pre-denaturation at 94 ℃ for 5 min, denaturation at 94 ℃ for 30 s, annealing at 50 ℃ for 1 min, extension to 72 ℃ for 90 s, a total of 35 cycles, final extension to 72 ℃ for 7 min. Finally, 175 locus of genomic DNA in total were detected from 10 ISSR primers and 155 were polymorphic locus, which covered 88.57%. The number of alleles(Na) was 1.8857 and the effective number of alleles(Ne) was 1.4300. Also, Nei’s gene diversity(H) was 0.2572 and Shannon’s information index(I) was 0.3959. UPGMA cluster analysis showed that according to the similarity coefficient of 0.74, the 35 copies of H. acerba germplasms could be classified into 4 groups. ISSR molecular marker techniques could well reveal genetic differences and the genetic diversity among H. acerba. The measured materials from 12 provenances of H. acerba showed abundant genetic diversity, which had great potential for exploitation and utilization. References | Related Articles | Metrics

Biological Activity of Ethanol Extract from Root of Zingiber striolatum BAI Ya-zhu, LIANG Shi, CHEN Liang-hua, HUANG Wen, XU Chuan-jun, TONG Qing-xuan, LIN He-tong, MING Yan-lin 2019, 48(04): 321-328.  DOI: 10.3969/j.issn.1009-7791.2019.04.003 Abstract ( )   PDF (3160KB) ( )   The biological activity of anti-oxidation, anti-nitrification and anti-liver cancer in vitro was determined by measuring the extracts of Zingiber striolatum root with 75% ethanol and samples eluted by five different concentrations of ethanol. The anti-oxidant activities of six test samples were compared by scavenging DPPH and ABTS free radicals in vitro. The inhibiting nitrosation ability of the six test samples was compared by in vitro nitrite removal and blocking nitrosamine synthesis. The relative survival rates of the six samples against human hepatoma cell lines HepG2 and SMMC7721 were compared by MTT assay. The results showed that the antioxidant activity of samples eluted with different ethanol concentration gradients was better than that of the total crude extract of 75% ethanol; the inhibition of nitrification of ZC-Ⅱ(75% ethanol crude extract washed with 25% ethanol) was the best, and of which the IC50 values ??for removing nitrite and blocking nitrosamine synthesis were 8.198 mg·mL-1 and 1.270 mg·mL-1, respectively. The MTT results showed that the anti-livers effect of ZC-Ⅴ, 75% ethanol crude extract washed with 95% ethanol, could reach upto 95.6%. There was a dose-dependent effect. It was concluded that the biological activity of the samples eluted with different ethanol concentrations was higher than that of the total crude extracts, and the biological active sites were mainly concentrated in the small polar sites.

Ethanol was used to induce damage of HepG2 cells. The survival rate of HepG2 cells after treatment with C. indicum extract was used to evaluate the liver protective effect. The results showed that the antioxidant ability of ethanol extract was better than that of water extract. Ethanol extract of C. indicum had a good scavenging effect on ABTS. The cell viability assay of alcoholic liver injury showed that the survival rates of the 5, 10, 20 μg·mL-1 treatment groups of C. indicum aqueous extract and alcohol extract were all significantly higher than that of the ethanol injury group (eth). The survival rate exhibited dose dependence. The ethanol extract of C. indicum had a more significant liver protective effect. References | Related Articles | Metrics

The growth and development of red flesh pitaya flower and fruit was regulated by applying supplement light, increasing temperature and nutrition in the study. Four cultivars of red flesh pitaya were induced three batches winter-spring flowers. The growth conditions of red flesh pitaya flower and fruit during growing period were observed. The results showed that the flower and fruit growing period of red pitaya was affected significantly by temperature, and there was a significantly negative correlation between growing period and temperature. The results also showed that the red flesh pitaya growing periods of three batches were obvious difference. The growing period of flower and fruit was shortest while the temperature was highest in the shed. The minimum critical temperature was great different between flower-bud growth and fruit growth, which were 9 ℃ and 15 ℃ respectively. References | Related Articles | Metrics

The results showed that different types of fruit bags had significant effect on inner temperature and light of bagging A. ×atemoya, which also had obvious effects on fruit appearances and solid contents. The single-layer black inner and yellow outer bag was light tight, while the inner temperature was highest at night, in which the fruit solid contents were higher than those in single-layer white bag and single-layer half lucency half white bag, but the fruit color was yellowish-white and worst. The single-layer white bag had transmission of light, and the inner temperature was higher than single-layer black inner brown outer bag at day. The fruit color in single-layer white bags were better than others, its fruit was light green. The light intensity in single-layer half lucency half white bag was biggest, but the difference of fruit color and solid contents was not obvious compared with single-layer white bag. The differences of fruit size, weight of singe fruit, length and roughness of carpopodium in different types of fruit bags were not obvious. References | Related Articles | Metrics

Progress of Betalains Biology XU Su-xia, HUANG Qing-yun, LIN Chun-song, HE En-ming 2019, 48(04): 378-383.  DOI: 10.3969/j.issn.1009-7791.2019.04.014 Abstract ( )   PDF (904KB) ( )   Betalains are water-soluble nitrogen-containing pigments, which accumulate in flowers, fruits and occasionally in vegetative tissues of plants, belonging to most families in Caryophyllales, and fungi. Betalains comprise the red-violet betacyanins and the yellow betaxanthins. There are about 75 betalains structurally and unambiguously identified from plants. Besides roles similar to anthocyanins in plants, betalains are pigments exerting antioxidant and radical scavenging activities. Betalains biosynthesis begins with tyrosine, including four or five enzymatic reactions and spontaneous reactions. In this paper, new advances of betalains biology are reviewed.
