Diversity Analysis and Identification of RAPD Markers in Relation to Sugar Accumulation in Sugarcane

The genomic DNA of six high sugar varieties (CoC 671, CoM 0254, Co 94012, MS 202, CoM 9908 and Q 63) and a low sugar variety CoM 0251 were amplified using 20 RAPD primers in order to identify their diversity. The result showed that all the primers produced polymorphic bands. However, based on percent polymorphism eleven primers (OPB-01, OPB-02, OPB03, OPB-04, OPB 07, OPB 09, OPB-11, OPB-12, OPB-13, OPB-14, OPB-16, OPB-18 and OPB-20) were found to be most informative. In the present investigation, eight amplified products were obtained using primers OPB 02 (1827, 1524, 883 bp); OPB 03 (1456 bp); OPB 04 (881 bp); OPB 07 (1889 bp, 946 bp) and OPB 09 (2001 bp) which were consistently present in six high sugar varieties and found to be absent in low sugar variety. A variety, Q 63 is quite often used as a parent in sugarcane breeding programme aimed at evolving high sugar varieties. Primer OPB-08 and OPB-03 showed a distinct band of ∼550 bp and ∼750 bp, respectively, in CoC 671, Co 94012 and Q 63. Q 63 is one of the parents of CoC 671 and Co 94012 is a somaclonal variety of CoC 671. Dice Similarity Coefficient revealed similarity index range from 0.513 to 0.710. Consensus tree indicates that the seven sugarcane varieties studied fall into three clusters. The low sugar content variety CoM 0251 was found to be most distinct and formed an independent cluster. The study suggest that converting the sequence information of these amplified products into SCAR marker can definitely help in reliable screening of sugarcane genotypes.

UPAYA PENINGKATAN PRESTASI BELAJAR SISWA MATA PELAJARAN EKONOMI DENGAN MENGGUNAKAN MODEL PEMBELAJARAN KOOPERATIF TIPE TSTS (TWO STAY TWO STRAY) PADA SISWA KELAS X A SMA PGRI 1 MAOSPATI MAGETAN TAHUN PELAJARAN 2012/2013

Based on initial observations and interviews with high school Economics teacher PGRI 1 Maospati Magetan note that the average value of the cognitive aspects of students in the class XA is 62. These results indicate that the numbers are still low com- pared to other classes. The learning process is commonly carried out using a model of discourse as a whole, namely the delivery of content to students and interspersed ques- tions and answers. This leads to learning as students tend to be passive and less meaning- fullearning for students. Students gain experience less direct, and less teacher provides opportunities as well as self- confidence in the students to be active in learning. It also adversely affects the affective aspects of students. Based on these problems researchers to make improvements by implementing cooperative learning model of two stay two stray ( TSTS ). The learning model involves students actively in learning activities. Pakok mind model of cooperative learning are two stay two stray provide an opportunity for groups to share results and information to other groups. The approach used in this study is a qualitative approach to classroom action research that consists of 2 cycles. Research subject is class XA SMA PGRI 1 Maospati Magetan , the number of 32 stu- dents. Data collection methods used in this study is a test of the cognitive aspects of economic subjects in the form of daily tests at the end of the cycle, and affective aspects of the observation sheets during the learning process. The results of observations of stu- dents' learning in classroom situations XA SMA PGRI 1 Maospati Magetan increased, namely: ( 1 ) The interest and attention of students in the learning process from 67.25% to 84.60% increased 17.35% ( 2 ) The active participation of students in asking from 54.10% to 68.25% an increase of 14.15% ( 3 ) the active participation of students in answering / expression from 52.22% to 69.45% increased 17.23% ( 4 ) the level of stu- dent discipline in the process of learning from 60.500/0 to 78.13% 17.63% an increase. The results of observations III group activities has increased, namely: ( 1 ) The active participation of students in an opinion from 51.58% to 68.75% increased 17.17% (2) The active participation of students in asking from 50.60% to 66.68% increased 16.08% (3)the active participation of students in answering questions from 53.12% to 71.88% increased18.76% (4) Respect tile opinion of friends from 55.50% to 74.850/0 increased 19,35% (5) Cooperation in completing a task group from 60.35% to 78.25% 17.90% an increase. Another thing shown by the increased learning outcomes from 65.63 % to 84.38%. Thus there is an increase of 18.75% .While the average value of learning outcomes in the first cycle is 71 increased to 82 in the second cycle. Learning model two stay two stray ( TSTS ) can improve cognitive and affective aspects of students by providing a learning environment that is fun discussions, opportunities for students to learn actively exchange information with peers and materials, conveying the idea to friends, submit answers and questions discussion of the problem, and it requires cooperation within the group.

Minimum-cost planning of the multimodal transport of pipes with evolutionary computation

Every day many kilometres of European highways are blocked by traffic jams. Congestion on roads and at air- ports adds the EU's fuel bill with a corresponding rise in pollution levels. In short, our present patterns of transport growth are unsustainable. One way of easing road congestion is to develop the efficient end-to-end movement of goods using two or more forms of transport in an integrated transport chain. We will focus on the multimodal transport problem that in- volves finding the most economical route in the distribution of cast iron ductile piping with or without mortar joint, both of different diameters and from different possible supply points to different points of destination over three transport net- works, road, rail and sea, which may have routes in common. The orders are made for quantities in linear metres of pipes. The economic cost of the transport on the various routes is dependent on the number of lorries, freight wagons and plat- forms required, and as these quantities must be obviously integer numbers. In practical applications the search space is di- mensionally very high, often there exist attractors into the search space due to the existence of multiple global optimum so- lutions, the cost function has discontinuities, many constraints, etc. The problem that has to be resolved is of great com- plexity, even using evolutionary algorithms. Our experience gained working several years in this optimization problem is described in this paper, to highlight that there is a need using evolutionary algorithms with certain learning ingredients and using strategies that progressively impose with more and more severity in the evolutionary optimization process the real scenario of the complex problem to get convergence to the global optimal solutions and simultaneously to obtain low com- putational cost total.

Drought Stress Induces Changes in the Non-Structural Carbohydrate Composition of Wheat Stems

The effect of drought stress on the non-structural carbohydrate (NSC) composition and water relations of the wheat (Triticum aestivum L.) stem has been investigated. Five separate parts of the stem were sampled: the unsheathed portion of the peduncle (Stem 1a), the sheathed portion of the peduncle (Stem 1b), the penultimate internode (Stem 2), the lower internodes (Stem 3+4) and the flag-leaf-pulvinus (pulvinus). The NSC was analysed as two fractions, an ethanol-soluble carbohydrate (ESC) fraction containing mono- and di-saccharides and some low molecular weight oligosaccharides, and a water-soluble carbohydrate (WSC) fraction containing mostly fructans and some high molecular weight oligosaccharides. In Stems 1b, 2 and 3 +4, the imposition of drought midway through grain filling resulted in a shift in soluble carbohydrate from the WSC to the ESC fraction indicating hydrolysis of fructans. In Stem 2 on day 29 of grain filling, the WSC/ESC ratio was 7.6 � 1.5 in well watered plants in contrast to 0.5 � 0.1 in droughted plants on day 30, even though NSC concentration did not differ. The NSC content of Stem la and the pulvinus increased threefold under drought, although levels were significantly lower than in the rest of the stem. The WSC/ESC ratio in these tissues was low com- pared to the rest of the stem but still declined noticeably under drought stress. Turgor (P) was fully maintained in Stem 2 and the pulvinus of droughted plants. Under drought, P in the pulvinus was maintained at higher levels (1.9-2.4 MPa) than in Stem 2 (0.8-1.2 MPa).
