Plant insect-resistantgenetic engineering hasopened a new way to prevent and cure against the insect pest incrop and wood productions. With the progresses instudies, many insect-resistantgeneswere cloned and characterized. The classification of most insect-resistantgenes from plant, the functionalmechanism and the applications of theplantinsect-resistantgenes, the problems and prospectsforusing the plant insect-resistant genes in genetic engineering was described.

Diffusion tensor imaging(DTI) is an efficient and noninvasive tool to investigate the characteristics and functions of white matter fiber tracts,and it can be used to study the relationship between the structure and function in the nervous system,the plasticity and damage repair of visual development,abnormalities of the white matters that relate to the visual pathways.Recently,the quantification of white matter fiber tracts from the lateral geniculate bodies to the occipital lobe visual cortex using DTI offers morphological information for the function and structure of the white matters during visual development.Some studies attempt to compare the DTI outcomes and tractography between amblyopic children and normal children so as to better display the variations of optic radiation in children with amblyopia,and to evaluate the relationship between structure and function of the white matters.DTI becomes an important supplementary research approach in these fields.This paper reviews the application of DTI in visual development and amblyopic eyes.

With development of wide-host-range vector systems,Tn5 transposon and its derivative vectors have been widely applied to genetic research of gram-negative bacteria.The applications of Tn5 transposon mutagenesis technology to genetic researches of bacteria were briefly discussed,including researches on biological control mechanisms of biocontrol bacteria,identification of bacterial essential genes,discovering virulence genes of bacterial pathogens,characterization of metabolism regulatory genes and genetic improvements of bacteria.
