Genetic imprints of domestication for disease resistance, oil quality, and yield component traits in groundnut (Arachis hypogaea L.)
Ploidy difference between wild Arachis species and cultivated genotypes hinder transfer of useful alleles for agronomically important traits. To overcome this genetic barrier, two synthetic tetraploids, viz., ISATGR 1212 (A. duranensis ICG 8123 × A. ipaensis ICG 8206) and ISATGR 265-5A (A. kempff-mercadoi ICG 8164 × A. hoehnei ICG 8190), were used to generate two advanced backcross (AB) populations. The AB-populations, namely, AB-pop1 (ICGV 91114 × ISATGR 1212) and AB-pop2, (ICGV 87846 × ISATGR 265-5A) were genotyped with DArT and SSR markers. Genetic maps were constructed for AB-pop1 and AB-pop2 populations with 258 loci (1415.7 cM map length and map density of 5.5 cM/loci) and 1043 loci (1500.8 cM map length with map density of 1.4 cM/loci), respectively. Genetic analysis identified large number of wild segments in the population and provided a good source of diversity in these populations. Phenotyping of these two populations identified several introgression lines with good agronomic, oil quality, and disease resistance traits. Quantitative trait locus (QTL) analysis showed that the wild genomic segments contributed favourable alleles for foliar disease resistance while cultivated genomic segments mostly contributed favourable alleles for oil quality and yield component traits. These populations, after achieving higher stability, will be useful resource for genetic mapping and QTL discovery for wild species segments in addition to using population progenies in breeding program for diversifying the gene pool of cultivated groundnut
Groundnut
Groundnut, a crop rich in nutrients, originated in South America and
spread to the rest of the world. Cultivated groundnut contains a fraction of
the genetic diversity present in their closely related wild relatives, which is
not more than 13 %, due to domestication bottleneck. Closely related ones
are placed in section Arachis , which have not been extensively utilized
until now due to ploidy differences between the cultivated and wild relatives.
In order to overcome Arachis species utilization bottleneck, a large
number of tetraploid synthetics were developed at the Legume Cell
Biology Unit of Grain Legumes Program, ICRISAT, India. Evaluation of
synthetics for some of the constraints showed that these were good sources
of multiple disease and pest resistances. Some of the synthetics were utilized
by developing ABQTL mapping populations, which were screened
for some biotic and abiotic constraints. Phenotyping experiments showed
ABQTL progeny lines with traits of interest necessary for the improvement
of groundnut
A survey of payment challenges in fraud detection in digital transactions methodologies
Any theft of the real card (Credit) or the arrangement of the card data, or potentially cardholder data, is the start of a Visa fraud. A vendor store agent duplicating deal receipts is one example of a tradeoff that can occur in a variety of ways. Because of the wide geographic reach that security lapses on databases holding MasterCard data might have, security lapses on databases including MasterCard data can be particularly large and costly. In one example in 2005, 40 million Visa customer accounts were stolen as a result of a single trade off of a massive database including charge card information. This had global consequences since fresh cards had to be issued to a huge number of cardholders all over the world. There are mays of credit card fraud, in this paper I concentrate some of them. Now a days we are facing a risk in payment of card, everyday payment for the exchange has been increasing as a result of the rising technique of instalment type and the introduction of new channels for the exchange.
