Green light for gene targeting in plants.
P recision engineering of eukaryotic organisms requires efficient techniques for homology-based replacement of an endogenous gene by an introduced gene, a process termed gene targeting (GT). Because foreign DNA is preferentially integrated by nonhomologous recombination in plants and animals, special strategies are needed to increase the frequency and facilitate the detection of GT. Developing ...
متن کاملDiscovery of second gene for solid dark green versus light green rind pattern in watermelon.
The watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus) has high variability for fruit size, shape, rind pattern, and flesh color. This study was designed to measure the qualitative inheritance of rind phenotypes (solid dark green vs. light green). For each of the 2 families, "Mountain Hoosier" × "Minilee" and "Early Arizona" × "Minilee," 6 generations (P(a)S(1), P(b)S(1), F(1)...
متن کاملProkaryotic evolution in light of gene transfer.
Accumulating prokaryotic gene and genome sequences reveal that the exchange of genetic information through both homology-dependent recombination and horizontal (lateral) gene transfer (HGT) is far more important, in quantity and quality, than hitherto imagined. The traditional view, that prokaryotic evolution can be understood primarily in terms of clonal divergence and periodic selection, must...
متن کاملGreen light for selected baby
Zain Hashmi is a three-year-old little boy from northern England with big brown eyes and a fatal disease, beta thalassaemia major. As his bone marrow is unable to produce sufficient numbers of red blood cells, he needs regular transfusions and is unlikely to survive for long unless transplanted with suitable stem cells. These could come from the bone marrow of a donor with matching tissue type,...
متن کاملA green light for new research.
water on culture medium, let it incubate, and see if any bacterial colonies develop. But that technique demands lots of waiting, and you might prefer a quicker technique-say, one that allows you to watch the bacteria grow in real time. Laura Leff of the department of biological sciences at Kent State University in Ohio does just that-watches bacteria grow right before her eyes-by labeling them ...
