The study was conducted to assess the socio-economic characteristics of camel marketers at Mai'adua livestock market in Katsina state. Random technique methods were used to select 45 marketers and an interview was used to generate the information. All the correspondents were males and married. Majority (46.67%) were between the age category of 35-40 years and only 11.11% were 55 years and above. Majority (75.56%) attended Qur'anic schools. Niger republic was the major source of the camels as indicated by 68.89% of the respondents while 17.78% and 11.11% indicated Katsina and Jigawa states respectively. Among the animal brought to the marker for sales males out-numbered the females while in the frequency of sales, females out-numbered the males because of variation in prices as indicated by 71.17% and 55.5% of the respondents respectively. Majority of the camels purchased were transported to Kano main abattoir for slaughter: There was variation in prices between males and females, stages of growth and development and physiological status. Camel calf (male) had a high price of N70,000 and above while that of female costs N60,000 and above, bull and heifer are sold at a minimum of N90,000 to N95,000 and N70.000 to N75,000 while old camel bull and cow were sold at medium price of between N160,000-N165,000 and N130,000-N135,000 respectively. However; (53.33%) of the respondents indicated lack of weighing devices as a major constraint and most (46.67%) indicated inconsistency in pricing among others. I seasonal variation was said to determine the demand. During early rain' season, farmers purchased male camel bulls for farming activities as indicated by the respondents (40.00%). Lack of awareness on the importance of camel meat also posed a constraint as camel meat was widely consumed (73.33%) in the area. Cost of camels increased during Eid-El-Kabir as indicated by 44.44%. The study reported information on marketing, sources, uses and destination of camels respectively.

Cell and tissue interactions are a basic aspect of eukaryotic growth and development. While cell-to-cell interactions involving recognition and incompatibility have been studied extensively in animals, there is no known antigen-antibody reaction in plants and the recognition mechanisms operating in plant grafts have been virtually neglected.An ultrastructural study of the Sedum telephoides/Solanum pennellii graft was undertaken to define possible mechanisms of plant graft incompatibility. Grafts were surgically dissected from greenhouse grown plants at various times over 1-4 weeks and prepared for EM employing variations in the standard fixation and embedding procedure. Stock and scion adhere within 6 days after grafting. Following progressive cell senescence in both Sedum and Solanum, the graft interface appears as a band of 8-11 crushed cells after 2 weeks (Fig. 1, I). Trapped between the buckled cell walls are densely staining cytoplasmic remnants and residual starch grains, an initial product of wound reactions in plants.

Calcium is an important element in the growth and development of plants and one form of calcium is calcium oxalate. Calcium oxalate has been found in leaf seed, stem material plant tissue culture, fungi and lichen using one or more of the following methods—polarized light microscopy (PLM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction.Two methods are presented here for qualitatively estimating calcium oxalate in dried or fixed tobacco (Nicotiana) leaf from different stalk positions using PLM. SEM, coupled with energy dispersive x-ray spectrometry (EDS), and powder x-ray diffraction were used to verify that the crystals observed in the dried leaf with PLM were calcium oxalate.

Cytokinins are plant hormones that play a large and incompletely understood role in the life-cycle of plants. The goal of this study was to determine what roles cytokinins play in the morphological development of wheat. To achieve any real success in altering the development and growth of wheat, the cytokinins must be applied directly to the apical meristem, or spike of the plant. It is in this region that the plant cells are actively undergoing mitosis. Kinetin and Zeatin were the two cytokinins chosen for this experiment. Kinetin is an artificial hormone that was originally extracted from old or heated DNA. Kinetin is easily made from the reaction of adenine and furfuryl alcohol. Zeatin is a naturally occurring hormone found in corn, wheat, and many other plants.Chinese Spring Wheat (Triticum aestivum L.) was used for this experiment. Prior to planting, the seeds were germinated in a moist environment for 72 hours.

Ethylene Signalling

Ethylene is the simplest unsaturated hydrocarbon, yet it has profound effects on plant growth and development, including many agriculturally important phenomena. Analysis of the mechanisms underlying ethylene biosynthesis and signalling have resulted in the elucidation of multistep mechanisms which at first glance appear simple, but in fact represent several levels of control to tightly regulate the level of production and response. Ethylene biosynthesis represents a two-step process that is regulated at both the transcriptional and post-translational levels, thus enabling plants to control the amount of ethylene produced with regard to promotion of responses such as climacteric flower senescence and fruit ripening. Ethylene production subsequently results in activation of the ethylene response, as ethylene accumulation will trigger the ethylene signalling pathway to activate ethylene-dependent transcription for promotion of the response and for resetting the pathway. A more detailed knowledge of the mechanisms underlying biosynthesis and the ethylene response will ultimately enable new approaches to be developed for control of the initiation and progression of ethylene-dependent developmental processes, many of which are of horticultural significance.
