Review with Checklist of Fabaceae in the Herbarium of Iraq Natural History Museum
Review with checklist of Fabaceae in the herbarium of Iraq natural history museum Khansaa Rasheed Al-Joboury * Iraq Natural History Research Center and Museum, University of Baghdad, Baghdad, Iraq. GSC Biological and Pharmaceutical Sciences, 2021, 14(03), 137–142 Publication history: Received on 08 February 2021; revised on 10 March 2021; accepted on 12 March 2021 Article DOI: https://doi.org/10.30574/gscbps.2021.14.3.0074 Abstract This study aimed to make an inventory of leguminous plants for the purpose of identifying the plants that were collected over long periods and stored in the herbarium of Iraq Natural History Museum. It was found that the herbarium contains a large and varied number of plants from different parts of Iraq and in different and varied environments. It was collected and arranged according to a specific system in the herbarium to remain an important source for all graduate students and researchers to take advantage of these plants. Also, the flowering and fruiting periods of these plants in Iraq were recorded for different regions. Most of these plants begin to flower in the spring and thrive in fields and farms. Keywords: Fabaceae; Herbarium; Iraq; Natural; History; Museum 1. Introduction Leguminosae, Fabaceae or Papilionaceae, which was called as legume, pea, or bean Family, belong to the Order of Fabales [1]. The Fabaceae family have 727 genera also 19,325 species, which contents herbs, shrubs, trees, and climbers [2]. The distribution of fabaceae family was variety especially in cold mountainous regions for Europe, Asia and North America, It is also abundant in Central Asia and is characterized by great economic importance. -
Specificity in Legume-Rhizobia Symbioses
International Journal of Molecular Sciences Review Specificity in Legume-Rhizobia Symbioses Mitchell Andrews * and Morag E. Andrews Faculty of Agriculture and Life Sciences, Lincoln University, PO Box 84, Lincoln 7647, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +64-3-423-0692 Academic Editors: Peter M. Gresshoff and Brett Ferguson Received: 12 February 2017; Accepted: 21 March 2017; Published: 26 March 2017 Abstract: Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N2) via symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia symbioses in field soils was reviewed and genotypically characterised rhizobia related to the taxonomy of the legumes from which they were isolated. The Leguminosae was divided into three sub-families, the Caesalpinioideae, Mimosoideae and Papilionoideae. Bradyrhizobium spp. were the exclusive rhizobial symbionts of species in the Caesalpinioideae, but data are limited. Generally, a range of rhizobia genera nodulated legume species across the two Mimosoideae tribes Ingeae and Mimoseae, but Mimosa spp. show specificity towards Burkholderia in central and southern Brazil, Rhizobium/Ensifer in central Mexico and Cupriavidus in southern Uruguay. These specific symbioses are likely to be at least in part related to the relative occurrence of the potential symbionts in soils of the different regions. Generally, Papilionoideae species were promiscuous in relation to rhizobial symbionts, but specificity for rhizobial genus appears to hold at the tribe level for the Fabeae (Rhizobium), the genus level for Cytisus (Bradyrhizobium), Lupinus (Bradyrhizobium) and the New Zealand native Sophora spp. (Mesorhizobium) and species level for Cicer arietinum (Mesorhizobium), Listia bainesii (Methylobacterium) and Listia angolensis (Microvirga). -

Sesbania Punicea (Cav.) Benth
A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Sesbania punicea (Cav.) Benth. Red sesbania Family: Fabaceae Range: Not widespread in the western United States. Occurs throughout the southeast from Virginia to eastern Texas and a few localities in California. Habitat: Riparian corridors, coastal plains and disturbed sites such as roadsides, ditches, canals and areas adjacent to ornamental plantings. In regions with long, dry summers, red sesbania invades moist areas. Survives occasional freezes but not harsh winters. It is most likely to spread to wildlands adjacent to or downstream from ornamental plantings. Origin: Native to South America (Argentina, Brazil, Paraguay, and Uruguay). Introduced to the United States as an ornamental. Impacts: Red sesbania grows rapidly and forms dense stands so thick that access to riparian areas becomes difficult to impossible. It displaces native vegetation used by wildlife and contributes to bank erosion and flooding. Large infestations can decrease water flow and reduce recreational uses. Sesbania can fix nitrogen, which enables the plant to colonize and dominate areas with poor soil. Increased soil nitrogen fertility gives a competitive advantage to other non-native weeds that thrive on high nitrogen levels. -

DECLARATION I declare that this thesis is my own original work and has not been submitted for any other unit for academic credit. William Michael Fowler Soil seed bank dynamics of transferred topsoil: evaluating restoration potentials ABSTRACT Global change, increasing human population growth and urbanisation represent increasing pressures on biodiversity and ecosystem function. It is now widely recognised that conservation of existing natural fragments will not be sufficient to maintain extant biodiversity or meet conservation goals. Thus there is a major and rapidly expanding need for the practice of ecological restoration whereby degraded lands are managed to increase and maintain indigenous species. A soil seed bank germination experiment was conducted over a period of 13 weeks. -

The effects of dry-storage on dormancy and germination were studied in seven desert legumes. Mature seeds were collected in summer 2017 and germinated within one week of collection (fresh) and after six months (dry-storage) under two temperature and two light regimes. Seed weight of two species increased 22-55% within 24 hours of water imbibition but others increased ≤ 7%. Germination ranged from 0-32% in fresh and 2-92% in dry-stored seeds, indicating a mix of non- and physically-dormant seeds at maturity. Dry-storage at ambient room temperature was effective at relieving dormancy, though the extent was species-dependent. Germination percentage increased in response to light exposure during incubation, while the effect of temperature was species-dependent. -

Ecological Applications 30(5):e02096. 10.1002/eap.2096 Abstract. Plant community responses to global environmental change focus primarily on aboveground vegetation; however, the important role of the seed bank is frequently neglected. Specifically, the direct and indirect effects of changes in temperature and precipitation on seed banks remain poorly understood, yet seed banks provide a vital source of ecosystem resilience to global environmental change. We used a structural equation model to explore the direct and indirect effects of temperature, precipitation, and other biotic and abiotic factors on soil seed bank community composition using 1,026 soil seed bank samples from 57 sites along an eleva- tion gradient that served as a space-for-time substitution for changing climate in the Tibetan Plateau. Seed bank richness was negatively correlated with both precipitation and temperature, but neither climate factor affected seed bank density. Temperature was also negatively corre- lated with vegetation species richness, which was positively correlated with seed bank richness and density. Both precipitation and temperature were positively correlated with soil total N, and total N was negatively correlated with vegetation richness. -
