Anatomical variations in wood among four native species of leguminosae grown in arid areas of China

Forestry Studies in China 2007年第1期9卷 39-44页

作者： Yang Shu-min Jiang Ze-hui Ren Hai-qing Ikuo Furukawa Research Institute of Wood Industry Chinese Academy of Forestry Beijing 100091 E R. China Faculty of Agriculture Tottori University Koyama Tottori 680-8553 Japan

Morphological features and anatomical variations are described and illustrated in detail for four native species of Legnminosae grown in arid sandy regions in China, which are Hedysarum scoparium *** Mey., Caragana korshiskii Kom., Lespedeza bicolor Turcz. and Ammopiptanthus mongolicus （Maxim. ex Kom.） Cheng f. All species showed similar morphological features： distinct growth ring boundaries, ring to semi-ring-porosity, simple perforation plates, alternate intervessel pitting, nonseptate fibers, paratracheal confluent axial parenchyma, helical thickenings and heterocellular rays. However, the vessel arrangement and their quantitative features were different. A. mongolicus had smaller vessel diameters and larger vessel fi＇equency, while the values in the other three species were similar, but bigger than those in A. mongolicus. The variation of vessel lengths and fiber lengths along a horizontal direction showed an irregular tendency. There were significant differences in both fiber lengths and vessel element lengths among trees and within trees, except for A. mongolicus. The relationships between anatomical features of secondary xylem and the adaptability of these species to desert environments are also discussed.

A Phylogenetic and Biogeographic Study of Cercis (leguminosae)

引用

Acta Botanica Sinica 2001年第12期43卷 1275-1278页

作者：郝刚张奠湘郭丽秀张明永邓云飞文香英中国科学院华南植物研究所广州510650

Cercis (L.) (leguminosae) consists of approximately 8 species, disjunctly distributed in eastern and western Asia, southern Europe, and North America. Phylogenetic analysis was performed using sequences of the internal transcribed spacer ( ITS) of the nuclear ribosomal DNA. The two North American and one Southern European and Western Asian species consistently form a clade, nesting within the eastern Asian species, suggesting a slightly closer relationship between the North American and Southern Europe-Western Asian species than each with the Eastern Asian species of Cercis. A close relationship between the eastern and western North American species is furthermore demonstrated, although with weaker support. The possibilities of migration via either the Bering land bridges or the North Atlantic land bridges could not be precluded; it suggests that the biogeographic patterns in the Northern Hemisphere are complex.

Comparative Analysis of EST Mining Reveals High Degree of Conservation among Eight leguminosae Species

Journal of Agricultural Science and Technology(B) 2013年第6期3卷 447-458页

Fabaceae is the third largest family of flowering plants and is unique among crops in their ability of fixing atmospheric nitrogen. Fabaceae is one of the few plant families with extensive genomic data available in multiple species. The unprecedented complexity and impending completeness of these data create opportunities for discovering new approaches. The Legume and Medicago share much-conserved colinearity between their genomes which can be exploited for the genomic research in leguminosae crops. In this study, 1,952,191 ESTs of 8 leguminosae species were clustered into unigenes contigs and compared with Medicago truncatula gene indices. Almost all the unigenes of leguminosae species showed high similarity with Medicago genes, except for those of Lens culinaris, where 95% of unigenes were found similar. A total of 10,874 SSRs were identified in the unigenes. Functional annotation of unigenes showed that the majority of the genes are present in metabolism and energy functional classes. It is expected that comparative genomic analysis between Medicago and related crop species will expedite research in other Legume species. This would be helpful for genomics as well as evolutionary studies, and the DNA markers developed can be used for mapping, tagging and cloning of specific important genes in leguminosae.

Pollen of Bauhinia *** Phanera Lour.(leguminosae-Caesalpinioideae)from the Brazilian Caatinga

引用

American Journal of Plant Sciences 2012年第7期3卷 909-920页

作者： Francisco de Assis Ribeiro dos Santos Danovan de Matos Novaes Luciano Paganucci de Queiroz Programa de Pós-Graduacao em Botanica Universidade Estadual de Feira de SantanaFeira de SantanaBahiaBrazil

A study of pollen morphology, in species of the genera Bauhinia and Phanera (leguminosae-Caesalpinioideae) which occur in the Brazilian caatinga, is presented. The pollen was examined using light and scanning electron microscopy. Samples were prepared by the KOH method;non-treated pollen grains were examined by scanning electron microscopy. Pollen grains in Bauhinia species (11) are colpate, but porate in B. cheilantha and B. subclavata. All four species of Phanera present colporate pollen grains;P. outimouta is the only to have syncolporate pollen grains. Species of both genera present heteromorphism in the number of apertures. Excepting P. outimouta whose pollen grains are psilate, all species in the two genera present supratectal processes (gemmae/clavae), however the exine in the two genera are dif- ferent–semitectate, reticulate in Bauhinia species, and tectate, rugulate (or psilate) in Phanera ones. Pollen characters support the segregation of Phanera from Bauhinia.

Effects of different rotation patterns on the occurrence of clubroot disease and diversity of rhizosphere microbes

引用

Journal of Integrative Agriculture 2020年第9期19卷 2265-2273页

作者： YANG Xiao-xiang HUANG Xiao-qin WU Wen-xian XIANG Yun-jia DU Lei ZHANG Lei LIU Yong Institute of Plant Protection Sichuan Academy of Agricultural SciencesChengdu 610066P.R.China Key Laboratory of Integrated Pest Management on Crops in Southwest Ministry of Agriculture and Rural AffairsChengdu 610066P.R.China

Clubroot disease, caused by Plasmodiophora brassicae, is one of the most destructive soil-borne diseases in cruciferous crops worldwide. New strategies are urgently needed to control this disease, as no effective disease-resistant varieties or chemical control agents exist. Previously, we found that the incidence rate and disease index of clubroot in oilseed rape decreased by 50 and 40%, respectively, when oilseed rape was planted after soybean. In order to understand how different rotation patterns affect the occurrence of clubroot in oilseed rape, high-throughput sequencing was used to analyze the rhizosphere microbial community of oilseed rape planted after leguminous (soybean, clover), gramineous (rice, maize) and cruciferous (oilseed rape, Chinese cabbage) crops. Results showed that planting soybeans before oilseed rape significantly increased the population density of microbes that could inhibit P. brassicae (e.g., Sphingomonas, Bacillus, Streptomyces and Trichoderma). Conversely, consecutive cultivation of cruciferous crops significantly accumulated plant pathogens, including P. brassicae, Olpidium and Colletotrichum (P<0.05). These results will help to develop the most effective rotation pattern for reducing clubroot damage.

Three new prenylated stilbenes, named as cajanusins A-C(1-3), and one new natural product cajanusin D(4), along with six known derivatives(5-10) were isolated from the leaves of Cajanus cajan. Their structures were fully elucidated by means of extensive spectroscopic methods and comparison with data in the reported literatures. The new compounds of 1 and 2 were evaluated for in vitro cytotoxic activities against a panel of human cancer cell lines.
