Varieties Grown in South-western Nigeria <p>Maize, a highly cultivated multipurpose cereal has different varieties grown globally. Six majorly known varieties (Hybrid red solo- V1, Red solo- V2, Solo- V3, Popcorn- V4, Small white- V5 and Big white- V6) found in south-western Nigeria were purposefully selected because of their abundance across the region and were analyzed for their proximate composition. Their composition of different nutrients varied; % crude fat was significantly higher in V5 (4.25%), V4 had a significantly higher % ash content of 1.93%, % crude protein ranged from 9.32% 15.75%, V2 had a significantly low % crude fibre of 0.86%, while V1 had a significantly higher % carbohydrate content of 74.40%. Knowledge of the levels of nutrients present in the different varieties will help in choosing the variety that can suit any intended purpose. V6 (Big white) seems to be the most preferable for human and animal consumption because of its significantly high content in protein and crude fibre coupled with a considerably high fat content.</p> Olufunso Omowunmi Adeniyi Oluwole Sesan Ariwoola ##submission.copyrightStatement## 2019-01-27 2019-01-27 7 1 1 5 10.21467/ias.7.1.1-5 Physiochemical Analysis of Sandalwood (Santalum Album) Leaf Litters Degraded by Eisenia foetida and Eudrilus eugenia <p>The decay of leaf litter by microflora and fauna furnish nutrient supply to the soil and also uphold ecological sustainability. Applying of proper technique and exploring of result provides information for the betterment of agricultural system. Vermicomposting of Sandalwood <strong>(</strong><em>Santalum album</em>) leaf litters were studied with an emphasis of physio-chemical deviation during the process and also compared with 100 % cattle dung. Obtained result explore that temperate of 50 % leaf litter (LL) and 100 % cattle dung (CD) was slightly elevated (37ºC ±1 ºC and 35ºC ±1 ºC respectively) at beginning phase and later came down to ambient level (20ºC±1 ºC). The total organic carbon (TOC) exhausted 44 % in 50 % LL Vermicomposting mixture while 70 % in 100 % CD during the process. At the final stage, TOC found more in 50% LL as compared to 100% CD. Nitrogen content was found 1.02<strong>±</strong>0.1 in 50 % LL and 0.88<strong>±</strong>0.1 in 100 % CD at the initial phase but after completion of Vermicomposting, their level was increased up to 40 to 44 %.&nbsp; pH was also measured during vermicomposting and found 7.2<strong>±</strong>0.1 in 50% LL while 8.4<strong>±</strong>0.1 in 100% CD at the initial phase. The at the end of process pH raised and set up to 8.2 <strong>±</strong>0.1 in 50% LL while in 100% CD it was found 8.0 <strong>±</strong>0.1.</p> Praveesh Bhati Ritu Nagar Anurag Titov ##submission.copyrightStatement## 2019-02-10 2019-02-10 7 1 6 11 10.21467/ias.7.1.6-11 Symptom Severity of Nicotiana benthamiana Plants Inoculated with Agrobacterium Containing Infectious DNA-A Clones of Honeysuckle Yellow Vein Virus (HYVV) <p>To investigate the pathogenicity and virulence of the <em>Honeysuckle yellow vein virus </em>(HYVV) lacking betasatellites, PCR amplified unit-lengths of DNA-A genome of HYVV-[DJ] were cloned into binary vector pRI101-AN, and generated HYVV-[DJ]-1mer, -1.3mer and -2mer genomes. Each construct was transformed into <em>Agrobacterium </em>cells and agro-inoculated into young leaves of <em>Nicotiana benthamiana</em>. Except for the HYVV-[DJ]-<em>1mer, </em>HYVV-[DJ]-<em>1.3mer and -2mer </em>clones caused pronounced disease symptoms in <em>N. benthamiana.</em> HYVV-[DJ]-2mer agro-inoculated plants showed more severe plant stunting with downward leaf curling and crinkling than those of HYVV-[DJ]-1.3mer agro-inoculated plants. To discriminate the clone’s virulence quantitatively, SYBR Green-based real-time PCR was performed for the quantification of the target virulence gene DNA in agro-inoculated plants that were collected at weekly intervals for 4 weeks. Regression analysis obtained the standard curves by plotting Ct values over the logarithm of the amount of V1 protein gene DNA present in a dilution series of plasmid containing the full-length HYVV-[DJ] genome. Equation of the HYVV <em>V1</em> DNA standard curve was used to quantify <em>V1</em> gene DNA concentration in agro-inoculated plants with each clone. The accumulation of <em>V1</em> gene DNA in HYVV-[DJ]-1.3mer agro-inoculated plants reached the peak level at 4 weeks post inoculation, while the accumulation of <em>V1</em> gene DNA in HYVV-[DJ]-2mer agro-inoculated plants reached the peak level at 3 weeks post inoculation. The amount of <em>V1</em> DNA in HYVV-[DJ]-1.3mer agro-inoculated plants was significantly more than that in HYVV-[DJ]-2mer agro-inoculated plants. Considering the results, there was a difference between the accumulation of virus DNA and the symptom severity of the analyzed plants agro-inoculated with each clone. It suggested that the infectious clones’ virulence is not necessarily correlated with the symptom severity.</p> Sung Oh Chang Won Choi ##submission.copyrightStatement## 2019-04-17 2019-04-17 7 1 12 20
