Haploid plants produced by centromere-mediated genome elimination

M Ravi, SWL Chan - Nature, 2010 - nature.com
Production of haploid plants that inherit chromosomes from only one parent can greatly
accelerate plant breeding 1 , 2 , 3 . Haploids generated from a heterozygous individual and …

Gamete formation without meiosis in Arabidopsis

M Ravi, MPA Marimuthu, I Siddiqi - Nature, 2008 - nature.com
Apomixis, the formation of asexual seeds in plants, leads to populations that are genetically
uniform maternal clones. The transfer of apomixis to crop plants holds great promise in plant …

Synthetic clonal reproduction through seeds

MPA Marimuthu, S Jolivet, M Ravi, L Pereira, JN Davda… - Science, 2011 - science.org
Cloning through seeds has potential revolutionary applications in agriculture, because it would
allow vigorous hybrids to be propagated indefinitely. However, asexual seed formation or …

Epigenetically mismatched parental centromeres trigger genome elimination in hybrids

MPA Marimuthu, R Maruthachalam, R Bondada… - Science …, 2021 - science.org
Wide crosses result in postzygotic elimination of one parental chromosome set, but the
mechanisms that result in such differential fate are poorly understood. Here, we show that …

[HTML][HTML] Meiosis-Specific Loading of the Centromere-Specific Histone CENH3 in Arabidopsis thaliana

M Ravi, F Shibata, JS Ramahi, K Nagaki, C Chen… - PLoS …, 2011 - journals.plos.org
Centromere behavior is specialized in meiosis I, so that sister chromatids of homologous
chromosomes are pulled toward the same side of the spindle (through kinetochore mono-…

Reverse breeding in Arabidopsis thaliana generates homozygous parental lines from a heterozygous plant

…, CLC Lelivelt, JJB Keurentjes, NS Naharudin, M Ravi… - Nature …, 2012 - nature.com
Traditionally, hybrid seeds are produced by crossing selected inbred lines. Here we provide
a proof of concept for reverse breeding, a new approach that simplifies meiosis such that …

Catastrophic chromosomal restructuring during genome elimination in plants

EH Tan, IM Henry, M Ravi, KR Bradnam, T Mandakova… - Elife, 2015 - elifesciences.org
10.7554/eLife.06516.001 Genome instability is associated with mitotic errors and cancer. This
phenomenon can lead to deleterious rearrangements, but also genetic novelty, and many …

The Rapidly Evolving Centromere-Specific Histone Has Stringent Functional Requirements in Arabidopsis thaliana

M Ravi, PN Kwong, RMG Menorca, JT Valencia… - Genetics, 2010 - academic.oup.com
Centromeres control chromosome inheritance in eukaryotes, yet their DNA structure and
primary sequence are hypervariable. Most animals and plants have megabases of tandem …

[HTML][HTML] A haploid genetics toolbox for Arabidopsis thaliana

M Ravi, MPA Marimuthu, EH Tan, S Maheshwari… - Nature …, 2014 - nature.com
Genetic analysis in haploids provides unconventional yet powerful advantages not available
in diploid organisms. In Arabidopsis thaliana, haploids can be generated through seeds by …

Rapid creation of Arabidopsis doubled haploid lines for quantitative trait locus mapping

…, IM Henry, J Monson-Miller, M Ravi… - Proceedings of the …, 2012 - National Acad Sciences
Quantitative trait loci (QTL) mapping is a powerful tool for investigating the genetic basis of
natural variation. QTL can be mapped using a number of different population designs, but …
