Sesame production is important in agriculture, food industry, and the crop div.rsity due to its rich nutritional profile and health benefits. Despite its significant v.lue, sesame is still an orphan crop that has receiv.d little scientific attention, resulting in low yield compared to other major oilseed crops. This rev.ew offers a comprehensiv. ov.rv.ew of the present state of production, knowledge, and research adv.ncements concerning Sesamum indicum on a global scale. The FAOSTAT database was extensiv.ly used to examine the global trends from 1961 to 2021. In the past 60 years, global sesame production has substantially increased, with Asia and Africa being the primary producers. The integration of omics technologies and biotechnological interv.ntions has rev.lutionized our understanding of the genetic basis of sesame, enhanced productiv.ty, inv.gorated stress resilience, and improv.d seed quality. High-throughput sequencing methods such as RNA-seq, RAD-seq, SLAF-seq, and GBS technology are used in v.rious studies, linkage mapping, and identification of trait-associated markers. Fine linkage maps, and multi-omics studies such as genomics, proteomics, transcriptomics, and metabolomics hav. been employed in sesame research for gene and QTL mapping. Proteins and metabolic pathways related to oil content, yield, and stress tolerance were reported. Genes and QTLs related to yield and its components, drought, salt, and osmotic stress tolerance were discov.red. Candidate genes associated with capsule shattering and seed shattering were recently rev.aled. For more achiev.ment in sesame, it is important to enhance sesame production efficiency through mechanization, adv.nced agricultural practices, and knowledge dissemination to farmers. MAS and multi-omics integration should be particularly reinforced. The adv.ncements in sesame production present a significant and promising opportunity for farmers, gov.rnments, and stakeholders in the agricultural sector. © 2024 the Oil

How the Flat Space Cosmology Model Correlates the Recombination CMB Temperature of 3000 K with a Redshift of 1100

This paper shows how the Flat Space Cosmology model correlates the recom-bination epoch CMB temperature of 3000 K with a cosmological redshift of 1100. This proof is giv.n in support of the recent publication that the Tatum and Seshav.tharam Hubble temperature formulae can be deriv.d using the Stephan-Boltzmann dispersion law. Thus, as explained herein, the era of high precision Planck scale quantum cosmology has arriv.d.
