Research Advances in Metabolic Regulation, Storage and Transport of Carotenoids in Plants YU Yin-feng, LIU Qing-qing, LIU Xiao-chun, ZHANG Da-sheng, CUI Li-jie Subtropical Plant Science    2024, 53 (1): 80-88.   DOI: 10.3969/j.issn.1009-7791.2024.01.012 Abstract （86）      PDF（pc） （367KB）（6660）       Knowledge map    Save Carotenoids are a group of natural pigments widely found in plants, which are generally composed of C40 terpenoids and their derivatives, which are connected from end to end of 8 isoprene units. In plants, carotenoids not only make plant organs appear color, but also perform important biological functions. In recent years, although the biosynthesis pathway of carotenoids is relatively clear, the mechanisms of metabolic regulation, including storage and transport of carotenoids in vivo are not yet understood. This paper briefly summarized the research progress of the biosynthesis, storage localization of carotenoids and terpenoid transporters, and focused on the potential substances that mediate carotenoid transport and the methods of identifying carotenoid transporters, in order to provide a better understanding of carotenoid synthesis and transportation.

A Review of Ethylene Signal Transduction Pathway in Rice WANG Jia,FANG Jun,YI Wen-kai,TIAN Yun,LU Xiang-yang, Subtropical Plant Science    2011, 40 (02): 72-78.   DOI: 10.3969/j.issn.1009-7791.2011.02.022 Abstract （1850）      PDF（pc） （358KB）（6002）       Knowledge map    Save The ethylene signal components identi?ed so far in rice include receptors, EIN2 and EIN3 homologues, and CTR1, RTE1, EBF1/2 and EIN5 homologues that are reversely conservative in dicotyledon Arabidopsis and monocotledon rice. But based on the observation of ein2 and eil1 mutants of rice that there is not strong phenotypic difference between the two mutants and wild type, we conclude that ethylene signal in rice might be more intricate than in Arabidopsis. Given that rice uses ethylene to control many processes that do not exist in Arabidopsis, it seems that new mechanisms may exist in rice ethylene signal pathway. This article reviewed ethylene signal pathways, regulation of ethylene signal, and ethylene responses in rice plants. Reference | Related Articles | Metrics | Comments（0）

Visual Analysis of Effects of Nutrients on Plant Drought Responses Based on Bibliometrics ZHAO Yong-ju, OUYANG Sheng-nan, TIE Lie-hua, CUI Yong, DUAN Hong-lang Subtropical Plant Science    2022, 51 (5): 405-416.   DOI: 10.3969/j.issn.1009-7791.2022.05.012 Abstract （107）      PDF（pc） （409KB）（1934）       Knowledge map    Save Under global climate change, increasing number of studies indicate that the intensity and frequency of drought will continue to increase globally in the future, becoming the main factor restricting plant growth and leading to plant death. Many studies had found that nutrient addition could affect plant responses to drought stress, but there was a lack of literature tracking and visualization studies. Therefore, we conducted a comprehensive analysis on relevant research papers searched in Web of Science, mainly using bibliometric methods and R bibliometric packages. The results showed that the number of published papers on the effects of fertilization on plant drought responses continued to increase from 2008 to 2021, with the most rapid increase since 2018. Northwest A&F University had the largest number of publications in this field (43), and there was a close cooperative relationship among various institutions. Most of the research papers were published in agricultural and forestry journals, among which Agronomy-Basel had the largest number of papers and Global Change Biology had the highest H-index. The most frequent keywords during the 14 years included drought, climate change, fertilization, nitrogen, yield and water use efficiency. The results of cluster analysis showed that in a series of studies on the effects of nutrient addition on plant response to drought, researchers focused on the water use efficiency, plant yield and plant physiological dynamics. Based on the background of global climate change, we predicted that the mechanism of nutrient addition affecting plant drought response would be an important research direction in this field in the future.

Chloroplast Genome Characteristics and Phylogeny of the Genus Lycoris (Amaryllidaceae) FU Wen-fo, XIAO Tao, ZHANG Yong-hong Subtropical Plant Science    2023, 52 (4): 271-286.   DOI: 10.3969/j.issn.1009-7791.2023.04.001 Abstract （144）      PDF（pc） （6727KB）（1899）       Knowledge map    Save In this study, the basic characteristics and phylogenetic relationship of chloroplast genome sequences from 17 species of Lycoris were analyzed. The results showed that the chloroplast genomes of Lycoris had a typical quadripartite circle structure with a total length of 158 335–158 761 bp and a total GC content of 37.7%–37.8%. The number of genes was 133–137, and the number of protein-coding genes, rRNA genes, and tRNA genes were identical in different species. There were 41–57 interspersed repeats and 66–74 SSR loci detected, among which single nucleotide A/T repeats were the most frequent. Codon preference analysis showed that the number of coding codons ranged from 26 448 to 26 740. The RSCU values of 31 codons were greater than 1 and the third base of 29 codons were A or U, which indicated that Lycoris plant preferred codons ended with A or U. The results of chloroplast genome alignment and collinearity analysis exhibited highly conservative with no rearrangement and inversion observed. Higher variation frequency of non-coding regions versus coding regions was detected. The IR boundary analysis showed that rpl22, rps19 and ndhF genes in some species crossed the JLB or JSB boundary due to the contraction and expansion of the IR region. Nucleotide polymorphism analysis detected 7 highly variable genes or intergenic regions, trnG-UCC, atpF-atpH, psbC-trnS-UGA-psbZ, trnG-GCC-psbZ, rpl32, trnL-UAG- rpl32-ccsA, rps15-ycf1, which could be used as molecular markers for phylogenetic analysis. The molecular phylogenetic tree showed that all Lycoris species clustered closely and formed a monophyly, which supported the independent taxonomic status of the genus. Two traditional subgenera, Symmanthus and Lycoris, didn’t form monophyly separately, although distinguished in stamen and corolla. And it was still doubtable on the intrageneric circumscription based on the relative position of stamens and perianth. In addition, the phylogenetic analysis supported the perspective of the hybrid origin of L. anhuiensis, L. houdyshelii, L. straminea and L. rosea, with potential maternal species recommended.
