The induction efficiency was approximately 9.1% when meiotic stages of megasporogenesis from the diplotene stage to the diakinesis stage were exposed to a high temperature of 44掳C for 4h. Simple sequence repeat (SSR) markers revealed that the 2n gametes were derived from the RRIM 600 female...
aExpression pattern ofGCR1. The promoter ofGCR1fused with NLS-Staygold and stable transformed into wild type tomato. Leaves of ten-day-old seedlings were used for analysis. Propidium Iodide (PIE) staining was used to show the cell edge. Chloroplast auto-fluorescence is shown in blue. All im...
Vasa (Ddx4, DEAD box polypeptide 4), an extremely specific marker of germ cells in vivo, is an ATP-dependent RNA helicase that plays an essential role in germ cell development and gametogenesis. However, the expression and function information about this
Megasporogenesis is a key step during ovule development in angiosperms, but the small number and inaccessibility of these cells have hampered molecular and genome-wide studies. Thus, many questions remain regarding the molecular basis of cell specification, differentiation, and development in the ...
first-trimester ultrasound screeningprenatal diagnosisA pregnant woman was revealed to have fetal univentricular heart and megacystis by a routine first-trimester ultrasound. Chorionic villus sampling with the use of karyotyping and microarray found no causative etiologies. A further investigation with ...
