“…In addition, the BC2F 2 seeds had seed coats similar to those of wild soybeans (Supplementary Figure 5C). The seed coat is thought to be a major determinant of dormancy (Moïse et al 2005), and some loci controlling seed coat color have been shown to be associated with hard seededness in wild soybean (Sakamoto et al 2004). Zhou et al (2010) suggested that a major phenolic in the seed coat was functionally related to coat-imposed hard seededness in wild soybean.…”

With the first approval of a genetically modified (GM) soybean for uncontained use in Japan, information about hybrids of wild and GM or non-GM soybeans has become increasingly important. Therefore, we generated and characterized various hybrids between wild and GM or non-GM soybeans in a containment greenhouse, and investigated the inheritance of the cp4 epsps transgene and its effects on the hybrids. The hybrids inherited the cp4 epsps gene in a Mendelian fashion. The gene was stably expressed and produced functional protein, conferring glyphosate tolerance to the hybrids. We also examined the germination and survival rates of the second filial (F 2 ) seeds and those of hybrids backcrossed twice (BC2F 2 ) after a 3-month treatment at 4°C. Hybrids displayed similar germination characteristics as wild soybean after cold treatment. The majority of the BC2F 2 seeds survived as dormant seeds. There was no effect of the cp4 epsps gene on the survival rate. Furthermore, we examined the morphology, anthesis, and fecundity of the hybrids. On the whole, the F 1 , F 2 , and F 3 hybrids exhibited morphology, anthesis, and fecundity phenotypes that were intermediate between wild and cultivated soybeans; those of BC2F 2 hybrids were similar to those of wild soybean. Comparisons between GM and the corresponding non-GM hybrids did not reveal significant differences in fecundity. We suggest that hybrids containing half of their genes from wild soybean and half from cultivated soybean display fitness that are intermediate between wild and cultivated soybeans, whereas BC2F 2 hybrids have fitness similar to that of wild soybean. We also suggest that, despite being stably inherited, the cp4 epsps gene does not affect fitness in the absence of glyphosate treatment.

“…The maternally derived seed coat differentiates from the ovule integuments that surround the embryo sac and plays a major role in protecting the embryo and transferring nutrients from the maternal plant to the developing embryo (Fig. 1, A and C;Murray, 1987;Borisjuk et al, 2004;Moise et al, 2005). By contrast, the embryo and endosperm are direct descendents of the fertilized egg and central cell, respectively.…”

“…The CCU content is a universal and integrated index of extract phytotoxicity which depends on acceptor species, TPC (r = 0.4 and r = 0.6 for rapeseed and ryegrass respectively) and acceptor germination rate (r = 0.8 and r = -0.7 for rapeseed and ryegrass respectively). As some researchers stated (Moise et al, 2005), the different response of acceptor species to TPC depends on different anatomy and permeability of their seed coats, and thus determines different phenolics through inside seeds and calculated CCU content. A slighter inhibition of rapeseed germination, if opposed to that of ryegrass, may be founded due to different seed coat anatomy and, thus, its permeability.…”

Response of allelochemical activity of “Solidago” to different acceptor species “ex situ” during vegetation stages

A b s t r a c tAllelopathy refers to the beneficial or harmful effects of one organism on another by the release of biochemical. In phytocommunities, the secondary plant metabolites have the allelochemical potential and supress both seed germination and seedling growth playing an important role in determining initial establishment and subsequent spread of invasive species.The content of phenolic compounds was estimated to be different in aqueous extracts of S. canadensis due to their dissimilar accumulation in plant parts (root and shoot), growth stage and leachate concentration. As phenolics affect various physiological processes, thus altering the physiological and growth patterns of plants, the revealed TPC exhibited different allelopathic potential of S. canadensis extracts. Thus, the TPC and CCU data for the researched acceptor species suggested that S. canadensis might provide the considerably allelopathic influence on the species diversity or local out-compete of the native plants in new habitats.
