The study indicated that, solarization treatment receiving mulching with thin polythene sheet (0.03 mm) recorded significantly higher soil temperature at all stages. Soil temperature recorded in treatments with thin (0.03 mm), 0 medium (0.06 mm) and thick polythene sheet (0.12 mm) was 56.0, 54.4 and 53.7°C respectively. Soil temperature in primary nursery bed was significantly higher with longer duration of solarization than with short or medium duration 0 54.3, 54.4 and 55.3°C respectively. Thin (G ) or medium (G ) polythene sheet in combination with longer duration of 1 2 0 solarization (D ) significantly increased the soil temperature at all the intervals of study (57.3°C).Keywords

The study was conducted to explore the growth performance of different clones of Populus deltoides under farm forestry. The experiment was established during February, 2006 with six poplar clones under two environments i.e. pure poplar plantation and agroforestry plantation (poplar with wheat and mung) and laid out in Split Plot Design with three replications. Results of the studies revealed that all growth parameters of poplar clones i.e. DBH, height and crown spread exhibited better performance under agroforestry plantation. Overall, clone SWL 22 showed best performance under both the environments.Keywords

Sequence assembly is a difficult problem whose importance is continuously growing even recently the cost of sequencing has dramatically decreased. The computer simulation for the evolution of sequence assembly of linear sequences have demonstrated the importance of recombination of blocks of sequences. Repeated cycles of point mutagenesis, recombination and selection should allow in "in vitro" molecular evolution of complex sequences, such as proteins. A method for the reassembly of genes from their random DNA fragments, resulting in "in vitro" recombination is reported by Stemmer and there are some laboratory techniques also available that results in reliable sequencing of approximately 500 nucleotides (500-mers). If we have lots and lots of 500-mers than the original genome (from which these 500-mers may be obtained) sequence will be assembled. All such methods are based on image fragmentation reassembly. In this paper we are proposing a technique that is based on tabular form. In the proposed technique we develop a table, which has four rows and two columns and contained information about the base character and position of the base character in the DNA sequence.Keywords

Genome may contain several copies of the same gene. Although human genome contains about 3 billion base pairs, only 3% of it encodes protein. There are only about 25000 genes in human genome which encode about 100000 proteins by alternative splicing. Biological sequences are commonly of two types - unique and repeated. We are utilizing these properties of the sequences. The earlier algorithms either work on unique repeat or repeated repeat sequence. We are merging both methodologies to develop a new algorithm which collectively compress both type of sequences, i.e. we can apply the same compression algorithm on all types of sequences. This will definitely reduce our effort for developing different algorithm and it will be easier to apply one single algorithm rather using different algorithm. In this paper, a Biological sequence compression is proposed to compress both unique sequences, which are repeated in one area, and repeated sequences that are interspersed throughout the genome. The algorithm is also compared with existing ones and it is found to achieve better compression ratio than other.Keywords

The study was undertaken with the objectives to characterize and identify single nucleotide polymorphisms in exons 9 and 10 of lactoferrin gene in Murrah buffalo. Genomic DNA was isolated from 200 lactating Murrah buffaloes and exons 9 and 10 of lactoferrin gene were amplified using specific sets of primers, which resulted in amplicons of 332 and 209 bp respectively. Comparison of nucleotide sequence of exonic region of lactoferrin gene in Murrah buffalo with that of Bos taurus cattle revealed a total of 16 mutations comprising of 11 transition and 5 transversion type. Conceptualized translation of nucleotide sequence of exonic region revealed six amino acid changes (five in exon 9 and one in exon 10). The BLAST analysis revealed that exons 9 and 10 of lactoferrin gene in Murrah buffalo were 94 to 99 % identical with other species. The identified SNPs may serve as marker for selection of Murrah buffaloes for improved resistance to mastitis.Keywords

Carbon sequestration potential of eight recommended land-use systems of arid western Rajasthan was compared. Biomass C stock was maximum in farm forestry of Acacia tortilis (31.4 Mg C ha–1) followed by Prosopis cineraria and Hardwickia binata based silvoarable systems (8.8 and 10.6 Mg C ha–1). Soil C stock was also maximum in farm forestry (47.6 Mg C ha–1) followed by Ziziphus based systems (32.5–33.9 Mg C ha–1). About 50–78% of additional soil C stock was in the form of soil inorganic carbon. The total C sequestered (biomass + soil) over a period of nineteen years was in the order: farm forestry (49.80) > silvoarable systems (11.0–13.3) > hortipasture system (8.3) > agri-horti (5.5), silvopasture (5.4) and sole pasture (5.3) compared to –1.0 Mg C ha–1 in sole cropping.Keywords
