雄性核
英文
malepronucleus-
A total of 38 males and 24 females irradiated at the pronuclear stage survived and were available for testing.
在原核期受照中共有38隻雄性和24隻雌性存活下來，並可供試驗。Using the hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which sry transcription can be detected failed to yield any positive results of xist. female embryos at the pronucleus stage and 2 - cell failed to produce any positive result of sry and xist too. while since the 4 - cells period, xist is constantly transcribed until blastocyst stages
然後利用實驗一確定的pcr條件，以hprt為陽性對照，用巢式rt - pcr對小鼠早期胚胎進行xist基因的轉錄分析，結果發現，轉錄sry基因的睪丸組織以及雄性胚胎，從受精卵發育到囊胚的過程中，基本上不轉錄xist基因；不轉錄sry基因的雌性卵母細胞和雌性胚胎，從出現原核開始，到發育至2 -細胞期的過程中， xist基因一直不轉錄，但是，從4 -細胞期開始，一直到孵化前囊胚階段，雌性胚胎都轉錄xist基因。Injected group, 0. 1 % saccharin ( 1. 5 ~ 2ml / rat, in 5min ) intraoral infused group and cta group. the expression of endogenous leucin - enkephalin ( lek ) in the rat brain was observed and 5 parts of the thalamus including laterodorsal thalamic nucleus ( ld ), lateral part of mediodorsal thalamic nucleus ( mdl ), ventroposterolateral thalamic nucleus ( vpl ), ventroposteromedial thalamic nucleus ( vpm ) and reticular thalamic nucleus ( rt ) were comparatively researched before and after the acquisition of cta applying lek - immunocytochemistry. in behavioral experiment, 18 adult male sd rats were divided into normal cta group ( control ) and 2 naloxone i. p

異源四倍體鯽鯉是世界上首例人工培育的兩性可育的四倍體魚，這為研究四倍體的生物學特性提供了良好的實驗材料，本文對異源四倍體鯽鯉的遺傳特性進行了研究，主要包括其遺傳穩定性、雌核發育、雄核發育方面的研究。In order to select male nucleo - sterile new genotype, a tentative idea was put forward for the nucleo - male sterility to attach a tps ( thermo - photoperiod sensitivity ) and a selection strategy of combination of selection and identification, at the same time, the spring and summer sowing method were used to provide different environment conditions of appraising sterility and tps. the results indicated that ( 1 ) sterility could be appraised under the spring sowing environment and tps could be appraised under summer sowing environment. ( 2 ) under spring sowing environment, sterility could be selected, but not maintained. thereby, lines selected could only be selected as recorded selection method in the experiment. ( 3 ) and then, selection was carried out from spring sowing line selected into summer sowing in same line with tps to select plants. these plants through the intercrossing selection had been combined with sterility and tps. in this way, a new selection protocol for selection sterile line with tps was formed. it mainly involves the spring and summer sowing method, recorded selection method and the intercrossing selection method
為了選育新類型玉米雄性核不育系，提出了為玉米核不育性添加溫光敏感性的設想和選擇與鑒定相結合的策略，同時應用分期播種的方法為作物提供不同的生長和發育的環境條件，以鑒定玉米雄穗的育性變化和對不同環境條件溫光的反應.研究結果表明，春播環境下可鑒定和選擇玉米的不育性，夏播環境下可鑒定和選擇其溫光敏感性.針對玉米核不育性難以找到保持系的特性，結合兩種播期選擇兩種性狀.但春播環境下選擇的不育性群體難以通過選擇單株來保持其不育性，為記錄性群體選擇.通過從春播入選的雜合不育性優良株系群體轉移到其對應的夏播溫光敏感性入選的同一優良群體中進行優良單株選擇，能逐漸使不育性和溫光敏感性相結合而選育出純合溫光敏不育系.這種新的選擇程序主要包括應用分期播種法、記錄性選擇法和春夏兩季交叉式選擇法，使含有不育基因的可育株系逐步累積不育基因並增加了溫光敏感性而育成玉米溫光敏不育系The ultrastructural changes of microspore mother cells and tapetal cells in anthers during the abortion of male sterile cotton " kang a " were observed by comparing with its maintainer " kang b " and by using transmission electron microscopy
