At present, the identifying of rice nitrogen stress by the chemical analysis is time-consuming and laborious. Machine vision technology can be used to non-destructively and rapidly identify rice nitrogen status, but image acquisition via digital camera is vulnerable to external conditions, and the images are of poor quality. In this research static scanning technology was used to collect images...

Using subtractive hybridization a submergence-induced gene was identified from deepwater rice, OsUsp1, that encodes a homologue of the bacterial universal stress protein family. Sequence analysis revealed that OsUSP1 is most closely related to the bacterial MJ0577-type of ATP-binding USP proteins which have been suggested to act as a molecular switch. USP protein homologues appear to be ubiquit...

The recursion theorem in the weak form {e}(z) = x(e, z) (universal function not needed) and in Rogers form φφf(n)(z) = φn(z), and Rice theorem are proved a first time using programs in C, and a second time with scripts in Bash.

UNLABELLED Designed degenerate primers unlike conventional primers are superior in matching and amplification of large number of genes, from related gene families. DPPrimer tool was designed to predict primers for PCR amplification of homologous gene from related or diverse plant species. The key features of this tool include platform independence and user friendliness in primer design. Embedde...

The phenology of butterflies was analyzed in the Calakmul Region (CR) in the state of Campeche, México, over the course of 3 years. Altogether, 60,662 individuals were recorded, consisting of 359 species in 207 genera, 18 subfamilies, 5 families, and 2 superfamilies. Greatest species diversity was recorded during Oct and Nov. Monthly fluctuation in diversity was defined by rare species. Hesperi...

Observations are presented of nonlinear internal waves on the outer New England continental shelf during the summer Shelfbreak Primer study conducted between July 26 and August 5, 1996. Current and temperature measurements were made with an upward looking acoustic Doppler current profiler (ADCP) located on the 147 m isobath near the shelfbreak and three vertical thermistor moorings located upsh...

Name of Sequence. Chicken prolactin (PRL) gene. Genus and Species. Gallus gallus (chicken). Origin of Clones. Genomic DNA from Xing Hua Chinese native chickens was used as a template. Primers were designed based on exon/intron junctions of the genomic turkey PRL gene sequence (Kurima et al., 1995). Polymerase chain reaction (PCR) amplifications of the PRL gene were performed by using the follow...

The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable microorganisms in virtually any environmental source and has thus been used extensively in the assessment of environmental microbial diversity. This technique relies on the assumption that the gene sequences present in the environment are complementary to the "universal" primers used in their amplification. The re...
