Seventy two Black Bengal goats on road side grass based diet were fed on 0, 20, 40, 80, 100 or 120 g of fish meal (FM)/goat/day with or without ad libitum access to urea molasses block(UMB). The purpose was to assess the interaction of undegradable protein (UDP) and fermentable nitrogen(N) supplementation on feed intake, nutrient digestibility and growth of goats. Live weight gain of goats increased linearly with the increasing of dietary fish meal as an undegradable protein source. With the increasing level of fish meal the live weight gain(g/day) was 17, 23, 46, 48, 48 and 52 with urea molasses block and 12, 21, 31, 49, 47 and 47 without urea molasses block. It was concluded that the beneficial effects of urea molasses feeding to accelerate the dry matter intake, TDN intake and nutrient digestibility observed could not be exploited in terms of live weight gain.

Single nucleotide polymorphism (SNP) is an abundant form of genetic variation within individuals of species. DNA polymorphism can arise throughout the whole genome at different frequencies in different species. SNP may cause phenotypic diversity among individuals, such as individuals with different color of plants or fruits, fruit size, ripening, flowering time adaptation, quality of crops, grain yields, or tolerance to various abiotic and biotic factors. SNP may result in changes in amino acids in the exon of a gene (asynonymous). SNP can also be silent (present in coding region but synonymous). It may simply occur in the noncoding regions without having any effect. SNP may influence the promoter activity for gene expression and finally produce functional protein through transcription. Therefore, the identification of functional SNP in genes and analysis of their effects on phenotype may lead to better understanding of their impact on gene function for varietal improvement. In this mini-review, we focused on evidences revealing the role of functional SNPs in genes and their phenotypic effects for the purpose of crop improvements.
Genome Sequencing, a Milestone for Genomic Research and Plant Breeding

Plant breeding programs are often used to improve varieties through creating diverse agronomic traits. During a breeding program, a lot of genetic diversities are created in the genome after different generations through homologous recombination. Genome sequencing technology has revolutionized the discovery of genes and molecular markers associated with diverse agronomic traits in crop improvement programs. Genomic research is now in the peak of success, thus creating new opportunities for crop improvement modern sequencing technology is now capable of sequencing thousands to millions of bases per run. Modern sequencing technologies enable the sequencing of different cultivars with small to complex genomes at a reasonable time and cost. These massive data can be used to identify important agronomic traits of crops such as fruit color, size, ripening, flowering time adaptation, grain yield, and quality maintenance. In addition, they can be used to develop crop varieties. This mini-review is focused on the role of genome sequencing in genomic research and plant breeding for crop improvements.
