Plant development is a process from germination of seed to vegetative growth, flower initiation and development, fertilization and finally to the next generation seed formation. A lot of achievements have been obtained in plant developmental biology in China. Since the 1990's, those young generation scientists returned to China from abroad to use molecular and genetic techniques to study morphological, physiological and biochemical process of plant development. The present paper reviews the progress in some research area of plant developmental biology in the past decades and also prospects the chance and future of plant developmental studies, due to the recent advances of plant genome sequencing and functional genomics in China under the international research background. 展开更多

It has benefited greatly from the recent technological advances in the field of systems biology. DNA microarray, phenome, interactome and transcriptome mapping, the new generation of deep sequencing technologies, and faster and better computational and modeling approaches have opened new frontiers for both systems biologists and developmental biologists to reexamine the old developmental biology questions, such as pattern formation, and to tackle new problems, such as stem cell reprogramming. As showcased in the International Developmental Systems Biology Symposium organized by Chinese Academy of Sciences, developmental systems biology is flourishing in many perspectives, from the evolution of developmental systems, to the underlying genetic and molecular pathways and networks, to the genomic, epigenomic and noncoding levels, to the computational analysis and modeling. We believe that the field will continue to reap rewards into the future with these new approaches. 展开更多

The process of double fertilization and the characters of embryo and endosperm development in an autotetraploid polyembryonic mutant rice IR36-Shuang were studied with a laser scanning confocal microscopy. Some abnormalities including degenerated ovary, abortive embryo sac, single fertilization, double-ovule and double-embryo and so on. were found dudng double fertilization and embryo development in IR36-Shuang. The rate of the abnormalities was 46.67% in IR36-Shuang, significantly higher than that in the control, an autotetraploid rice line IR36-4X (33.00%). Cytological and embryonic evidences were provided for seed setting decline and the initiation of additional embryo in IR36-Shuang. 展开更多

Background: In recent decades, there has been a growing interest in the impact of insults during pregnancy on postnatal health and disease. It is known that changes in placental development can impact fetal growth and subsequent susceptibility to adult onset diseases;however, a method to collect sufficient placental tissues for both histological and gene expression analyses during gestation without compromising the pregnancy has not been described. The ewe is an established biomedical model for the study of fetal development. Due to its cotyledonary placental type, the sheep has potential for surgical removal of materno-fetal exchange tissues, i.e., placentomes. A novel surgical procedure was developed in well-fed control ewes to excise a single placentome at mid-gestation.Results: A follow-up study was performed in a cohort of nutrient-restricted ewes to investigate rapid placental changes in response to undernutrition. The surgery averaged 19 min, and there were no viability differences between control and sham ewes. Nutrient restricted fetuses were smaller than controls(4.7 ± 0.1 kg vs. 5.6 ± 0.2 kg;P < 0.05), with greater dam weight loss(-32.4 ± 1.3 kg vs. 14.2 ± 2.2 kg;P < 0.01), and smaller placentomes at necropsy(5.7 ± 0.3 g vs. 7.2 ± 0.9 g;P < 0.05). Weight of sampled placentomes and placentome numbers did not differ.Conclusions: With this technique, gestational studies in the sheep model will provide insight into the onset and complexity of changes in gene expression in placentomes resulting from undernutrition(as described in our study),overnutrition, alcohol or substance abuse, and environmental or disease factors of relevance and concern regarding the reproductive health and developmental origins of health and disease in humans and in animals. 展开更多

Functional analysis of control genes is playing an important role in animal development.The research is mainly focused on developing a method of estimating the gene's effect or function in the development of animals.In this article,the gene's expression and control are described by models of quantitative genetics,which include the genetic models about the genes with no interaction and interaction effect.On this basis,a method analyzing the functions of control genes in batches is advanced,the method includes three steps as follows: Firstly,describe the gene's expression and control with multiple regression models in statistic method in different conditions.Secondly,collect the material of gene's polymorphism related to the gene's expression and control.Because,gene's polymorphism or the codominant molecular marker electropherogram in a gene locus present 3 states,and can be expressed with -1,0 and 1 respectively.The author thinks it can be regarded as levels in orthogonal layout.Discard the materials of gene's polymorphism not fitting the orthogonal layout,and use the materials of gene's polymorphism fitting the orthogonal layout as the data to estimate the gene's effects.Thirdly,analyze the gene's effect or function with equations as follows:suppose that a quantitative trait is controlled by N gene loci,in each locus there are two alleles,the alleles' effects are A GM1 ?a GM1 ;A GM2 ? a GM2 ;...;A GMi ?a GMi ;...;A GMN ;a GMN units respectively.When the genotype in a locus is heterozygous A GMi a GMi ,the interaction coefficient of alleles in a locus is K units.If there is no interaction among different gene loci,the author thinks,the gene's effects and gene's type can be estimated by using such equation: P GM =2∑Ni=1(A i-a i+K i)+∑Ni=1(A i-a i)M GMi -∑Ni=1K GMi M GMi 2 If there are interactions among different gene loci,and the effect of the x th gene's state combined with the y th gene's state in the k th gene group is defined as Y xyr ,and let gene group electropherogram states be r (where r∈ ),the author thinks,the gene group's effects can be estimated by the equation: Y xyr = K PCxy0 +K PCxy r+K PCxy' r 2+K PCxy'' 3+K PCxy(3') r 4+K PCxy(4') r 5+K PCxy(5') r 6+K PCxy(6') r 7+K PCxy(7') r 8 If there are interactions among more genes,the analogous method can also be used. In this way,be using the gene's codominent marker materials fitting the orthogonal layout,the gene's expression and control can be researched by the method of multiple regression,the gene's relative effect can be estimated,the overdominant gene's overdominant coefficient can be assessed,the gene's type can be identified,the interaction gene group's relative effect and the interaction gene's relation can be estimated as well,and furthermore,the gene's relation can be expressed in equations.For the sake of understanding the method used in this paper,the rout to prove it is given as well.Finally,the author thinks,this method is very useful to research the gene's function in molecular developmental biology. 展开更多

In celebration of JIPB's 60th anniversary, this paper summarizes and reviews the development process of the journal. To start, we offer our heartfelt thanks to JIPB's pioneer Editors-in-Chief who helped get the journal off the ground and make it successful. Academic achievement is the soul of academic journals, and this paper summarizes JIPB's course of academic development by analyzing it in four stages: the first two stages are mostly qualitative analyses, and the latter two stages are dedicated to quantitative analyses. Most-cited papers were statistically analyzed. Improvements in editing, pub- lication, distribution and online accessibility--which are detailed in this paper--contribute to JIPB's sustainable development. In addition, JIPB's evaluation index and awards are provided with accompany- ing pictures. At the end of the paper, JIPB's milestones are listed chronologically. We believe that JIPB's development, from a national journal to an international one, parallels the development of the Chinese plant sciences. 展开更多
