Late leaf spot (LLS) and rust have the greatest impact on yield losses worldwide in groundnut (Arachis hypogaea L.). With the objective of identifying tightly linked markers to these diseases, a total of 3,097 simple sequence repeats (SSRs) were screened on the parents of two recombinant inbred line (RIL) populations, namely TAG 24 × GPBD 4 (RIL-4) and TG 26 × GPBD 4 (RIL-5), and segregation data were obtained for 209 marker loci for each of the mapping populations.

With the aim of understanding the genetic basis and identification of quantitative trait loci (QTL) for drought tolerance, two new recombinant inbred line (RIL) mapping populations, namely ICGS 76 × CSMG 84-1 (RIL-2) and ICGS 44 × ICGS 76 (RIL-3), were used.

- - The study created a reference consensus genetic map for tetraploid groundnut using data from 10 recombinant inbred lines (RILs) and one backcross (BC) population, addressing the issue of insufficient marker density across its large genome.
- - This map features 897 marker loci (895 SSR and 2 CAPS) organized into 20 linkage groups, with an overall map distance of 3,863.6 cM and an average density of 4.4 cM, highlighting varying marker distributions across different linkage groups.
- - The map includes 203 BINs for better organization of marker loci and offers valuable polymorphism information content (PIC) for genetic analysis, making it essential for future genetic mapping,
Epigenetic events play a prominent role during cancer development. This is evident from the fact that almost all cancer types show aberrant DNA methylation. These abnormal DNA methylation levels are not restricted to just a few genes but affect the whole genome.
