荒漠草原4种典型草本植物群落土壤水分动态对极端干旱降水的响应
Shuitu Baochi Xuebao, 2023 为明晰荒漠草原典型植物群落土壤水分对极端干旱降水的响应。以4类典型植物群落(蒙古冰草、苦豆子、短花针茅、芨芨草)为研究对象,于2020-2021年分别监测4类植物群落0-120 cm土壤含水量,探讨其土壤水分在消耗期、恢复期和稳定期的动态特征及对降水的响应。结果表明:土壤水分消耗期,土壤含水量为4.56%~7.87%,呈亏缺状态,并且随着极端干旱持续从土壤浅层0-40 cm向深层80-120 cm演变;土壤水分恢复期,较为集中的Ⅴ级降水(单次＞20 mm)能够恢复深层80-120 cm土壤水分 ...

Hira基因产物在银鲫和彩鲫卵子发生过程中的动态变化 [PDF]
, 2010 为进一步研究Hira基因在卵子发生和雌核发育过程中的作用,通过原位杂交和免疫荧光定位的方法检测了Hira mRNA和蛋白质在雌核发育银鲫和两性生殖彩鲫卵子发生过程中的动态变化。结果表明,银鲫和彩鲫卵子发生过程中Hira基因转录产物的变化基本一致,在Ⅰ期卵母细胞的细胞核中大量表达,至Ⅱ期卵母细胞时转至细胞质中均匀分布,在Ⅲ期卵母细胞中,杂交信号逐渐移向细胞的周边,到Ⅳ期时随着卵黄物质大量积累,杂交信号几乎不见。HIRA蛋白在银鲫和彩鲫卵子发生过程中的变化略有差别。HIRA蛋白在银鲫Ⅰ期卵母细胞中没有表达,
