Cannabaceae is a small family of flowering plants. As now circumscribed, the family includes about 170 species grouped in about 11 genera, including Cannabis (hemp, marijuana), Humulus (hops) and Celtis (hackberries). Celtis is by far the largest genus, containing about 100 species. Other than a shared evolutionary origin, members of the family have few common characteristics; some are trees (e.g. Celtis), others are herbaceous plants (e.g. Cannabis). Members of this family can be trees (e.g. Celtis), erect herbs (e.g. Cannabis), or twining herbs (e.g. Humulus). Leaves are often more or less palmately lobed or palmately compound and always bear stipules. Cystoliths are always present and some members of this family possess laticifers. Cannabaceae are often dioecious (distinct male and female plants). The flowers are actinomorphic (radially symmetrical) and not showy, as these plants are pollinated by the wind. As an adaptation to this kind of pollination, the calyx is short and there is no ...

Cannabis, the botanical name of a group of annual flowering plants belonging to the Cannabaceae family, comes in two species. These species are Indica or Sativa. Most sativa strains were originally grown strictly to smoke. Indica strains can be smoked or made into hash and kif. When consumed, an Indica plant will produce more of a body high than sativa and they are best for relaxation, stress reduction, body pain relief, and overall calmness. Sativas are better for daytime use and are known to induce more of a cerebral, or mind, high. They, like the Indica strains, can also alleviate pain ...

Humulus, hop, is a small genus of flowering plants in the family Cannabaceae. The hop is native to temperate regions of the Northern Hemisphere. Hops are the female flowers (seed cones, strobiles) of the hop species H. lupulus; as a main flavor ingredient in beer, H. lupulus is widely cultivated for use by the brewing industry. Although frequently referred to as the hops "vine", it is technically a bine; unlike vines, which use tendrils, suckers, and other appendages for attaching themselves, bines have stout stems with stiff hairs to aid in climbing. It is a perennial herbaceous plant which sends up new shoots in early spring and dies back to the cold-hardy rhizome in autumn. Hop shoots grow very rapidly, and at the peak of growth can grow 20 to 50 centimetres (8 to 20 in) per week. Hop bines climb by wrapping clockwise (except for Humulus japonicus) around anything within reach, and individual bines typically grow between 2 to 15 metres (7 to 50 ft) depending on what is available to grow on. ...

Rhizobia are composed of specific groups of bacteria that have the ability to induce symbiotic nitrogen-fixing nodules on the roots or stems of leguminous plants. Rhizobia have attracted a great attention for more than 4 decades because of their enormous agricultural and economic value in sustainable agriculture. Up to the present time, many legumes have been found to be nodulated by several rhizobial species in diverse taxonomic groups. An assessment of rhizobial diversity provides pivotal information in understanding the horizontal gene transfer among bacterial genera and species, the bacterial evolution and the symbiotic effectiveness. The classification of rhizobia is becoming increasingly complex and is revised periodically because of new findings that propose new genera and new species. Phenotypic and Genotypic Diversity of Rhizobia presents the application of conventional and molecular analyses, including numerical analysis, enzyme patterns, serological studies, plasmid profile, ...

The QpHb1 gene is the first nonsymbiotic Hb gene that has been isolated from oak roots and characterized. The QpHb1 deduced protein shows characteristic features of other plant Hbs (Fig. 1). These include the CD1 phenylalanine, C2 proline and F8 proximal histidine residues needed for heme binding, and the E7 distal histidine which is involved in ligand binding (Ota et al., 1997). A cysteine residue found in most known plant nonsymbiotic Hbs is also present in QpHb1. Sequence comparison also confirmed the presence of the plant Hbs signature (SN)-P-x-(LV)-x(2)-H-A-x(3)-F (Dickerson & Geis, 1983). Based on these structural features, QpHb1 can be categorized as a class 1 nonsymbiotic Hb. Furthermore, the phylogenic analysis of QpHb1 with other known Hb sequences available in public resources highlights the fact that QpHb1 forms a cluster together with other woody species (Trema tomentosa, Trema orientalis, Parasponia andersonii, Alnus firma, Malus domestica), indicating its close primary structural ...

Revised received July 12, 2010. Abstract. A major strategy towards addressing soil fertility depletion is the conservation and sustainable use of rhizobia that are able to fix nitrogen in the soil in association with legumes. The study assessed abundance and diversity of legume nodulating rhizobia (LNB) in soils collected from six different land use systems in Embu District, Kenya. The populations were estimated by the most-probable-number (MPN) plant infection technique using Macroptilium atropurpureum (DC.) Urban (Siratro) as the trap host species. Symbiotic effectiveness was measured for the isolates in association with Siratro. Isolated rhizobia were characterized morphologically and genetically by PCR-RFLP and partial sequencing of 16S rRNA genes.. The LNB populations in soils collected from the different land uses in Embu ranged from 0 to 2.3 x 102 cells g-1 soil. There was apparent land use effect on abundance of LNB with fallow system giving high abundance. A total of 250 pure isolates ...

Just wondered how to store these Celtis occidentalis seeds. Can I just let them dry and then put them through a stratification of some sort next spring? Whats the best way? I have some I picked a couple of weeks ago and they are already starting to wrinkle up. Are they goners?

Rhizobium fredii is a fast-growing rhizobium isolated from the primitive Chinese soybean cultivar Peking and from the wild soybean Glycine soja. This rhizobium harbors nif genes on 150- to 200-megadalton plasmids. By passage on acridine orange plates, we obtained a mutant of R. fredii USDA 206 cured of the 197-megadalton plasmid (USDA 206C) which carries both nif and nod genes. This strain, however, has retained its symbiotic effectiveness. Probing EcoRI digests of wild-type and cured plasmid DNA with a 2.2-kilobase nif DH fragment from Rhizobium meliloti has shown four homologous fragments in the wild-type strain (4.2, 4.9, 10, and 11 kilobases) and two fragments in the cured strain (4.2 and 10 kilobases). EcoRI digests of total DNA show four major bands of homology (4.2, 4.9, 5.8, and 13 kilobases) in both the wild-type and cured strains. The presence of major bands of homology in the total DNA not present in the plasmid DNA indicated chromosomal nif genes. Probing of HindIII digests of total and

We are amending the Asian longhorned beetle (ALB) regulations by removing plants of the genus Celtis (hackberry) from the list of regulated articles, which we have determined not to be a host plant of ALB. This action is necessary to relieve restrictions on the movement of regulated articles that are not hosts of ALB. As a result of this action, there are no longer any restrictions on the movement of Celtis spp. plants from areas quarantined for ALB. This interim rule is effective June 16. We will consider all comments that we receive on or before August 15 ...

Trees benefit from some pruning in the nursery and landscape. Often, there are only a small number of large-diameter branches in the crown, and these can develop embedded bark next to the trunk if they are allowed to become very large relative to the size of the trunk. This problem can be avoided by pruning back these branches to slow their growth so more, smaller-diameter dominant branches develop in the crown. Be sure that branches arise from the trunk at a wide angle, and slow the growth of these branches by pruning. This will help the tree develop a strong branch structure since hackberry appears to develop embedded bark on major branches more often than some other trees. But large-diameter surface roots can form (particularly in poorly-drained soil) raising sidewalks and making mowing grass difficult. Locate the tree 8-feet or more from a sidewalk or street to help keep them intact.. Hackberry has a reputation for internal trunk rot, particularly following mechanical injury to the trunk. ...
