Guar [Cyamopsis tetragonoloba （l.） Taub.] is one of the most important industrial crops due to its richness in gum. Understanding the inheritance of gum content is a key to its successful genetic improvement. Gum content expression is reported to be controlled by additive, dominant, and epistatic effects, and modified by the environment, fg%, a relative gum content calculated by comparing with the gum content of Kinman was used as gum content （%） in this experiment. Reciprocal crosses of two lines of guar, PI 217923 and lewis, were made to study the heritability of gum content （fg%）. fg% of four plant introductions and four commercial varieties were studied in lubbock in 1999-2002. Estimates of broadsense heritability （h^2 b,s.） of fg% in lewis x PI 217923 and PI 217923 x lewis were 75.53 and 52.74%, respectively. Estimates of narrow-sense heritability （h2 n.s.） of fg% were 40.00 and 29.00% thr lewis x PI 217923 and PI 217923 x lewis, respectively. At least one pair of genes were estimated to control the fg% expression in these two crosses, Significant differences of fg% were found among these eight entries. PI 217923 was found to have the highest fg% among the eight entries.

The main goals of the study were to elucidate the mechanism of Al-induced behavioral toxicity and to explore the possible link between the changes in the metabolism of monoaminergic or cholinergic transmitters and neurobehavioral *** groups (12 rats in each group) were fed with aluminum chloride in drinking water (1600 mg/l) ad libitum through a 90-day exposure Period. The controls were fed with distilled water. From the 60th to 90th day of treatment, two of the three Al-treated groups were administered with l-dopa (220 mg/kg. bw) and eserine (0. 4 mg/kg. bw)by gavage, respectively. A twcritem neurobehavioral test battery consisting of step down test and Morris water maze task was used for rats after three months treatment. In thestepdown test, markedly shortened the step-down latency (SDl) and the number of step-down (NSD) were observed in the Al-treated group (P l). On the contrary, oniy slight changes were found in the rats treated with aluminum combined with l-dopa or eserine (P > 0. 05, vs control ). In eserine and l-dopa antagonized groups, the mean escape latencies of Morris water maze approached a level close to that of the controls (P >0. 05). The results showed that the Al-induced memory and learning impairment could be reduced by l-dopa or eserine. It is suggested that the depletion of dopaminergic and cholinergic transmitters in the central nervous system might play an important role in Al-induced neurotoxicty

Pepper flowers are hermaphroditic; the plant's male sterility trait is characterized by its inability to produce pollen grains. In the ABC model of flower development, B-function genes play roles in petal and stamen development in the angiosperm. In this study, a B-class gene designated as PAP3 (Gen Bank accession no. HM104635) was isolated in pepper. The gene encoded 226 amino acids and shared high similarity with the MADS-box protein family, with a conservative MADS domain and semiconservative K domain. Furthermore, the expression of PAP3 was abundant only in petals and anthers but not in leaves. A functional study employing virus-induced gene silencing(VIGS) showed that knockdown of PAP3 led to the shriveling of pollen grains and male sterility; however, it did not affect petal development. These results suggest an essential role for PAP3 in the development of the pepper stamen and in contributing to the variation of floral traits.

We study the ll-error of a Hamiltonian-preserving scheme, developed in [19], for the liouville equation with a piecewise constant potential in one space dimension when the initial data is given with perturbation errors. We extend the l1-stability analysis in [46] and apply the ll-error estimates with exact initial data established in [45] for the same scheme. We prove that the scheme with the Dirichlet incoming boundary conditions and for a class of bounded initial data is ll-convergent when the initial data is given with a wide class of perturbation errors, and derive the ll-error bounds with explicit coefficients. The convergence rate of the scheme is shown to be less than the order of the initial perturbation error, matching with the fact that the perturbation solution can be l1-unstable.

We study the l^l-error estimates for the upwind scheme to the linear advection equations with a piecewise constant coefficients modeling linear waves crossing interfaces. Here the interface condition is immersed into the upwind scheme. We prove that, for initial data with a bounded variation, the numerical solution of the immersed interface upwind scheme converges in l^l-norm to the differential equation with the corresponding interface condition. We derive the one-halfth order l^l-error bounds with explicit coefficients following a technique used in [25]. We also use some inequalities on binomial coefficients proved in a consecutive paper [32].
