Title: Excess Zn-induced changes in physiological parameters and expression levels of TaZips in two wheat genotypes

In this study, the whole genome DNA of sorghum apomixes line SSA-1 (Shanxi sorghum apomict-1) was injected into two rice varieties of &lsquo;Liaoyan&nbsp;28&rsquo; and &lsquo;Liaoyan&nbsp;6&rsquo; using the pollen tube pathway method. The genetic characters of the progeny changed obviously. By self-selection and identification, 27 phenotypic stable D 4 &nbsp;generation lines were obtained. Through field planting, the phenotypes of agronomic traits such as heading date, tiller number, plant height, and 1 000-grain weight of the introduced lines were statistically analyzed. The results showed that the agronomic traits of the D 4 &nbsp;generation lines were widely varied, some D 4 &nbsp;generation lines were more inclined to donor sorghum in culm and panicle&nbsp;color, which indicated that the whole genome DNA of sorghum was successfully introduced into the receptor cells, and the expression of the receptor gene was affected. Compared with the recipient parents, the introduced lines showed significant variations in the main traits such as heading date, tiller number, plant height, grain number per ear, grain weight per ear, ear length, and thousand grain weights. Further analysis and selection of mutant lines is helpful to discover new germplasm materials and provide abundant germplasm resources for breeding new rice varieties. 

Analysis of Main Characters of Rice Progenies by Injecting Sorghum DNA into Rice

Selenium (Se) deficiency causes a series of health disorders in humans, and Se concentrations in the edible parts of crops can be improved by altering exogenous Se species. However, the uptake, transport, subcellular distribution and metabolism of selenite, selenate and SeMet (selenomethionine) under the influence of phosphorus (P) has not been well characterized.The results showed that increasing the P application rate enhanced photosynthesis and then increased the dry matter weight of shoots with selenite and SeMet treatment, and an appropriate amount of P combined with selenite treatment increased the dry matter weight of roots by enhancing root growth. With selenite treatment, increasing the P application rate significantly decreased the concentration and accumulation of Se in roots and shoots. P1 decreased the Se migration coefficient, which could be attributed to the inhibited distribution of Se in the root cell wall, but increased distribution of Se in the root soluble fraction, as well as the promoted proportion of SeMet and MeSeCys (Se-methyl-selenocysteine) in roots. With selenate treatment, P0.1 and P1 significantly increased the Se concentration and distribution in shoots and the Se migration coefficient, which could be attributed to the enhanced proportion of Se (IV) in roots but decreased proportion of SeMet in roots. With SeMet treatment, increasing the P application rate significantly decreased the Se concentration in shoots and roots but increased the proportion of SeCys2 (selenocystine) in roots.Compared with selenate or SeMet treatment, treatment with an appropriate amount of P combined with selenite could promote plant growth, reduce Se uptake, alter Se subcellular distribution and speciation, and affect Se bioavailability in wheat.
