2050 yılında nüfusun 9.2 milyara ulaşacağı ve dünya genelinde eşit insani temel ihtiyaçlara olan taleplerin karşılanması gerektiği öngörülmektedir. Günümüze kadar, tarımsal üretimin arttırılmasına yönelik çeşitli çalışmalar gerçekleştirilmiştir. Bununla birlikte birim alandan daha yüksek verim alınmasını sağlayan yeni teknoloji yöntemlerin geliştirilip bitki ıslah programlarına entegre edilmesi...

Polyploidization is a major evolutionary process. Approximately 70-75% species of Triticeae (Poaceae) are polyploids, involving 23 genomes. To investigate intergenomic rearrangements after polyploidization of Triticeae species and to determine the effects of environmental factors on them, nine populations of a typical polyploid Triticeae species, Kengyilia thoroldiana (Keng) J.L.Yang et al. (2n...

We have determined the relationship between overall nuclear architecture, chromosome territories, and transcription sites within the nucleus, using three-dimensional confocal microscopy of well preserved tissue sections of wheat roots. Chromosome territories were visualized by GISH using rye genomic probe in wheat/rye translocation and addition lines. The chromosomes appeared as elongated regio...

In her article "Perspectives of Ethical Identity in Ng's Steer toward Rock and Jen's Mona in the Promised Land" Hui Su examines Fae Myenne Ng's and Gish Jen's novels. In the novels, the protagonists make different decisions: in Steer Toward Rock Jack after displacement in China adopts US-American identity and in Mona in the Promised Land Mona, a second generation Chinese American, selects Jewis...

The independent evolution of heteromorphic sex chromosomes in 19 species from 4 families of flowering plants permits studying X/Y divergence after the initial recombination suppression. Here, we document autosome/Y divergence in the tropical Cucurbitaceae Coccinia grandis, which is ca. 3 myr old. Karyotyping and C-value measurements show that the C. grandis Y chromosome has twice the size of an...
