Efficient Characterization of Tetraploid Watermelon [PDF]
Plants, 2019 Watermelon (Citrullus lanatus (Thunb.) Matsum. &Nakai) is an economic crop, which is widely cultivated around the world. The ploidy study of watermelon has an important role in field breeding and production, therefore, timely and convenient ploidy ...

Tetraploid development in the mouse [PDF]
Developmental Dynamics, 2003 AbstractSpontaneous duplication of the mammalian genome occurs in approximately 1% of fertilizations. Although one or more whole genome duplications are believed to have influenced vertebrate evolution, polyploidy of contemporary mammals is generally incompatible with normal development and function of all but a few tissues.

Introgression of A- and B-genome of tetraploid triticale chromatin into tetraploid rye [PDF]
Journal of Applied Genetics, 2013 An improvement of rye is one of the mainstream goals of current breeding. Our study is concerned with the introduction of the tetraploid triticale (ABRR) into the 4x rye (RRRR) using classical methods of distant crossing. One hundred fifty BC1F9 hybrid plants [(4x rye × 4x triticales) × 4x rye] obtained from a backcrossing program were studied.

In vivo polyploidy induction of Phalaenopsis amabilis in a bubble bioreactor system using colchicine
Ornamental Horticulture, 2021 Phalaenopsis amabilis Blume var. grandiflora Bateman is economically important as cut and pot flower. Polyploidy is considered as a valuable tool in improvement and evolution of ornamental plants. Protocorm-like bodies (PLBs) of P. amabilis were cultured

On the tetraploid origin of the maize genome [PDF]
Comparative and Functional Genomics, 2004 AbstractData from cytological and genetic mapping studies suggest that maize arose as a tetraploid. Two previous studies investigating the most likely mode of maize origin arrived at different conclusions. Gaut and Doebley proposed a segmental allotetraploid origin of the maize genome and estimated that the two maize progenitors diverged at 20.5 ...

Genome Size and Karyotype Studies in Five Species of Lantana (Verbenaceae)
HortScience, 2021 Lantana species are an important component of the U.S. environmental horticulture industry. The most commonly produced and used species are L. camara and, on a smaller scale, L. montevidensis. Both were introduced to the United States from Central and/or
