The International Oryza Map Alignment Project: development of a genus-wide comparative genomics platform to help solve the 9 billion-people question

Genomes of 13 domesticated and wild rice relatives highlight genetic conservation, turnover and innovation across the genus Oryza

“…IOMAP began with the generation of genomic tools (BAC libraries and physical maps) derived from wild accessions that have been actively used in breeding programs to introgress new traits into cultivated rice 88 . N 22)) and the closely related outgroup species L. perrieri.…”

Cold Tolerance in Rice Plants: Phenotyping Procedures for Physiological Breeding

“…Although is unclear the impacts of these changes on agricultural sustainability, in the current year the CO 2 concentration reached unprecedented registered levels on earth surface (about 403 ppm) (Olivier et al, 2017). In this way, add to challenges associated to feed more than nine billions people in the next decades (Jacquemin et al, 2013;Fan et al, 2014), an additional question is related to how to supply the food crescent demand for world growth population in face of increasingly uncertainties about climate stability; which could lead to change of rain regime, besides of increases in frequency of heat and cold waves as predicted to be increasingly common in next decades. In this sense, abiotic and biotic stresses are the major constraints for agricultural productivity on the global scale and projected climate changes could increase their negative effects in the future (Brito et al, 2010Diola et al, 2011;Diola et al, 2013;Weber et al, 2014;Brito et al, 2016;Guimarães et al, 2017;Lisei-de-Sa et al, 2017;Moura et al, 2017a;Moura et al, 2017b) and its increasingly frequency of occurrence will probably influence the plant species distributions, productivity, carbon balance and negatively impacting on physiological resilience capacity of plants in a specific environment.…”

Global Genomic Diversity of Oryza sativa Varieties Revealed by Comparative Physical Mapping

“…The genus Oryza contains 21 wild and 2 cultivated species (Oryza sativa and O. glaberrima) with 10 genome types (Ammiraju et al 2006;Jacquemin et al 2013). O. sativa is composed of two subspecies: japonica and indica (Han and Xue 2003).…”

“…Whole-genome sequences of japonica variety Nipponbare and indica variety 93-11 have been released and updated (Yu et al 2002 International Rice Genome Sequencing Project 2005;Gao et al 2013;Kawahara et al 2013), and massive comparisons between these two genomes have been carried out to reveal the genetic variations (Han and Xue 2003;Feltus et al 2004;Ma and Bennetzen 2004;Yu et al 2005;Ding et al 2007;Huang et al 2008). The Oryza Map Alignment Project (OMAP) has constructed bacterial artificial chromosome (BAC) libraries and BAC-based physical maps for 17 of 23 Oryza species representing all the 10 genome types (Ammiraju et al 2006(Ammiraju et al , 2010bKim et al 2008;Jacquemin et al 2013). These BAC-based resources make whole or targeted genomic comparisons available and shed light on the genomic variation and evolution (Kim et al 2007;Zhang et al 2007;Ammiraju et al 2008;Feng et al 2009;Lu et al 2009;Ammiraju et al 2010a;Hurwitz et al 2010).…”
