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.

The reform of teaching mode, arrangement of curriculum content and investigation for relevant theory can promote the development of the biology course, and can greatly improve the research value of developmental biology. Based on this, this paper will analyze the course content, the teaching mode and the content of multimedia courseware by combining with content of developmental biology.

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 ***: 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 developmental origins of health and disease in humans and in animals.

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.

In the current thesis, the developmental potency of murine cloned embryos that the enucleated oocytes and somatic cell nuclei came from the same or different individual donor (SID or DID) were evaluated. The nuclei from cumulus cells taken from adult B6D2FI strain were introduced into enucleated oocytes and the reconstructed embryos were activated by SrCI2 and cultured with CZB medium for development in vitro.

本项研究较系统地观察了温度对斑管巢蛛生长、发育、繁殖和寿命的影响,并在不同梯度的恒温条件下饲养和测定了斑管巢蛛的发育起点温度(C)和有效积温常数(K)。发育起点温度卵期为10.9℃,若蛛期为14.1℃,成蛛期为16.7℃,全世代为为14.9℃。有效积温卵期为105.8日度,若蛛期为833.4日度,成蛛期为196.2日度。完成一个世代需要有效积温1130.5日度。检验温度与斑和巢蛛生长发育的关系表现为逻辑斯缔曲线(logistic-curve)。根据试验结果还初步确定了斑管巢蛛的生存温度范围。
