Soybean [Glycine max (L.) Merr].
In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...
متن کاملPhysiological regulation of soybean (Glycine max L. Merr.) growth in response to drought under elevated CO2
To understand the physiological mechanism by which soybean (cultivar: Glycine max L. Merr. cv.JH13) regulates its growth in response to drought under elevated CO 2 concentration, a pot experiment with two levels of CO 2 (350 vs. 700 μmol·mol) and two levels of water (well irrigated vs. drought) was conducted. Plant relative growth rate (RGR), water potential (WP), photosynthetic pigment (chloro...
متن کاملAlcohol dehydrogenase (ADH) activity in soybean (Glycine max [L.] Merr.) under flooding stress
Sowing time of soybean (Glycine max [L.] Merr.) often coincides with the early onset of rainy season. Germinating seeds encounter a transient to prolonged period of water-logging that causes anoxia (absence of oxygen) and hypoxia (insufficient oxygen) resulting in poor germination. This reduces crop stability and yield. One of the factors responsible for flood tolerance is activity of alcohol d...
متن کاملEffect of Nitrate on Nodule and Root Growth of Soybean (Glycine max (L.) Merr.)
The application of combined nitrogen, especially nitrate, to soybean plants is known to strongly inhibit nodule formation, growth and nitrogen fixation. In the present study, we measured the effects of supplying 5 mM nitrate on the growth of nodules, primary root, and lateral roots under light at 28 °C or dark at 18 °C conditions. Photographs of the nodulated roots were periodically taken by a ...
