Explain: Corn is a C4 plant because it is a plant that needs and produces CO2 into four sugar compounds that enter the Calvin cycle.

The general population of New Guinea were most likely the first to cultivate sugarcane, at some point around 8,000 BC. After cultivation, its development spread quickly to Southeast Asia and southern China. India, where the procedure of refining cane juice into granulated precious crystals was produced, was regularly gone to by imperial escorts, for instance, those from China to assimilate about development and sugar refining. By the 6th century AD, sugar development and processing had achieved to reach to Persia; and, from that point that assimilation was brought into the Mediterranean by the Arab expansion.

Two NADPH are added to 1,3-Bisphophoglycerate creating Glyceraldehyde 3-phosphate which plant can convert it to glucose, cellulose, and starch with hexose monophosphate pool. With the conversion of six molecules of carbon we get fructose 6-phosphate that produce hexose sugars. Three molecules of carbon into one molecule of dihydroxyacetone phosphate. Due to that the cycle happens twice, which needs assist regenerating by a transketolase and an aldolase which interchange the carbon atoms. Starch and sucrose are carbohydrates bonded together for stored energy.

Ethanol is a green renewable energy that produces from lignocellulosic materials. In the process, rice straw and corn straw required the physical pretreatment, chemical pretreatment at 100oC for 2 hours, and consequently with cellulase hydrolysis at pH 4.8, 42oC. Therefore, the concentration of 2 - 4 %(v/v) of HCl and H2SO4 were applied. Moreover, the 4 %(v/v) of HCl solution released the highest amounts of total sugar, glucose, and xylose. The corn straw produced the total sugar at 61.43 g/L while rice straw generated 27.36 g/L. The HCl pretreatment released a higher amount of xylose than glucose, In the corn straws, the HCl pretreatment produced the 14.59 g/L of xylose and 7.46 g/L of glucose whereas, in the rice straw pretreatment, the process

Since "ATP from the light responses impacts parts of the Calvin cycle, it is the Calvin cycle that makes sugar, with the guide of ATP and NADPH from the light response" (The Calvin cycle The Nonlight Requiring Reaction, 2013) . The metabolic periods of the Calvin cycle are now and again alluded to as the light-free responses, since none of the strides needs light specifically. The crude materials for anabolic pathways and fuel for breath is given when Carbohydrates takes type of disaccharide sucrose set out through the veins to non-photosynthetic cells (Simon, Reece, and Dickey, 2013), and development of the extracellular polysaccharide cellulose. Cellulose is the most extreme ample natural atom and maybe the planet, and in addition the fundamental element of cell dividers in plants.

The sugar beets and sugar cane are very good examples of these feed stocks that contain the sugar. Corn contains starch that can easily be converted into the sugar that is needed. Even most of the trees and grasses have cellulose that can be easily turned into sugar and then used in the making of ethanol (Mukherjee 1 para 2).The ethanol process always starts by grinding up the feedstock which makes it more quickly and easily processed.

The structural carbon that dominates the tissues of many higher plants is comprised in large part of lignins and cellulose (Meyers & Ishiwatari, 1993). Lignocellulose degradation in terrestrial soil systems plays a central role in the global carbon budget, but currently the fundamental understanding of the degradation of these compounds is only rudimentary (Benner et al., 1988; Lynd et al., 2002; Martinez et al., 2005). Cellulose is the most prevalent component of plant tissue comprising 35-50% of dry weight, and is generally embedded in a biopolymer structural matrix including hemicelluloses (20-35% of dry wt.) and lignin (5-30% of dry wt.) (Lynd et al., 2002), with other biochemicals such as carbohydrates, lipids and proteins comprising a much smaller portion of plant tissues (Martinez et al., 2005). The lignocellulosic component of the plant undergoes self-assembly at the site of biosynthesis and is composed of randomly polymerized polyphenolics intertwined with hemicellulose, resulting in a hydrophobic crystalline or complex amorphous structure, which protects against biodegradation. Collectively these physical properties of lignocellulose do not present well-defined enzymatic targets, making it difficult for enzymes to bind to susceptible sites and thereby conferring considerable resistance to microbial degradation (e.g., Moran & Hodson, 1989). These characteristics of higher plant structural material have been

The results will provide strong evidence into the role and evolutionary history of Thioredoxin genes, and will help further investigation of the molecular and biological functions of Thioredoxin protein family in cotton.

Another study reported the fermentation of its hydrolysate yielded a maximum ethanol concentration of 10.44 g/l using Pichia stipitis, followed by 8.24 and 6.76 g/l for Candida shehatae and Saccharomyces cerevisiae (Das et al., 2015). Malveaux (1995) reported that at biomass production rate of 0.26 metric tons of dry biomass/ hectare/day under proven growing conditions in Louisiana yielded 9.62 metric tons of dry biomass per day thus producing 2020.2 kg of sugar for an experimental yield of 1131.3 liters of ethanol per day.

Primary hurdle in using lignocelluloses (component of biomass) for ethanol production is location of entrapped sugars necessary for fermentation. Other hindrances are physiochemical, structural and compositional factors [25]. To overcome these problems, pretreatment is necessary before fermentation so that cellulose becomes accessible in the plant fiber. This can be done through breakage of (β-1, 4) - glycosidic linkages between its monosaccharide sugar units [26]. However, the major challenge behind pre- treatment is its cost effectiveness. A number of agricultural crops like rice straw, wheat, cotton stalk, sugarcane bagasse are being used these days for bioethanol production [21]. Enzyme hydrolysis is widely used pretreatment method but there are chances of incomplete hydrolysis, therefore other ways are being tried at the same time. Alvira [27] explained fractionation of

Dry corn straws were ground and sieved using a 40-mesh sieve. Then, the resulting corn straw crash was made alkaline with 15% NaOH solution at 55 °C in a water bath for 2.5 h. The resulting solution was oxidized and bleached by H2O2, dried, and ground to get cellulose.

The greater the variation in DNA sequence, the easier it is to generate polymorphic markers. Therefore the plant species used for SCAR development should have sufficient variation for te traits of interest at both the DNA sequence and phenotypic levels. Researchers over the years have employed various non-sequence primed PCR markers to develop SCAR markers for the identification of sex in dioecious species of crop plants.

2011). Furthermore, population genomic tools have helped improve our understanding of phenotypic evolution in crop species like maize (Ducrocq et al. 2008; Hufford et al. 2012; van Heerwaarden et al. 2012), rice (Olsen et al. 2006), and sorghum (Morris et al. 2013; Lasky et al. 2015; Zhang et al. 2015).
