春季低温通常发生在冬小麦孕穗期,导致小麦大幅减产。本研究选用低温反应敏感型小麦品种‘皖麦52’和低温反应迟钝型小麦品种‘烟农19’作为试验材料,在孕穗期将小麦盆栽置于人工气候室内进行低温处理(-2和0℃),低温处理结束后分别喷施浓度为10、20、30 mg·L^(-1)的6-苄氨基腺嘌呤(6-BA)溶液,以喷施等量蒸馏水作为对照,探讨孕穗期低温胁迫后喷施6-BA对小麦旗叶部分生理特性、产量和品质的影响。结果表明:与对照相比,外源喷施6-BA处理的小麦幼穗形态较为饱满,小花形态得到改善,穗下节间维管束数目增加;6-BA促进了小麦旗叶可溶性糖、可溶性蛋白和脯氨酸的积累;过氧化物酶和超氧化物歧化酶活性提高,丙二醛含量降低。外源喷施6-BA后小麦退化穗数减少,穗粒数和千粒重提高,籽粒蛋白质、湿面筋含量和沉降值增加。综上,外源喷施6-BA可以有效缓解低温胁迫对小麦旗叶和产量造成的影响。在本试验条件下,喷施6-BA溶液对烟农19的缓解效果要高于皖麦52,其中以喷施20 mg·L^(-1)的6-BA溶液对低温胁迫的缓解效果最好。

Determining the location of the Cretaceous-Paleogene(K-Pg) boundary in terrestrial strata is highly significant for studying the evolution of terrestrial ecosystems at the end of the Cretaceous(especially the extinction of non-avian dinosaurs). At present, research on terrestrial K-Pg boundaries worldwide is concentrated in the middle and high latitudes, such as North America and Northeast China. Although many studies have also been carried out in the Nanxiong Basin, located at low latitudes(which has become the standard for dividing and comparing the continental K-Pg stratigraphy in China), many researchers have proposed four possible boundaries from different perspectives. Therefore, the exact location remains to be determined. In this study, the total mercury(Hg) content, environmental magnetism, geochemistry, and other parameters for the samples collected near the four boundaries were determined and compared with existing records. Results indicated that: 1) The total Hg content significantly increased in the upper part of the Zhenshui Formation and Pingling part of the Shanghu Formation with sharp fluctuations. As per latest dating results of Deccan Traps, the significantly high Hg value was attributed to the Deccan Traps eruption. Boundary 1 was located in the middle of the Hg anomaly interval, which was consistent with the relationship between the global K-Pg boundary and time of volcanic eruption. 2) The reconstructed paleoclimate evolution curve revealed that the red sediments in the basin recorded the late Maastrichtian warming event(66.2 Ma). Regarding the relationship between the four boundaries and this warming event, only boundary 1 was found to be closest to the real K-Pg boundary of the Nanxiong Basin.

The TET family is well known for active DNA demethylation and plays important roles in regulating transcription, the epigenome and development. Nevertheless, previous studies using knockdown（KD） or knockout（KO） models to investigate the function of TET have faced challenges in distinguishing its enzymatic and nonenzymatic roles, as well as compensatory effects among TET family members, which has made the understanding of the enzymatic role of TET not accurate enough. To solve this problem, we successfully generated mice catalytically inactive for specific Tet members(Tetm/m). We observed that, compared with the reported KO mice, mutant mice exhibited distinct developmental defects, including growth retardation, sex imbalance, infertility, and perinatal lethality. Notably, Tetm/mmouse embryonic stem cells（mESCs） were successfully established but entered an impaired developmental program, demonstrating extended pluripotency and defects in ectodermal differentiation caused by abnormal DNA methylation. Intriguingly, Tet3, traditionally considered less critical for m ESCs due to its lower expression level, had a significant impact on the global hydroxymethylation, gene expression, and differentiation potential of mESCs. Notably, there were common regulatory regions between Tet1 and Tet3 in pluripotency regulation. In summary, our study provides a more accurate reference for the functional mechanism of Tet hydroxymethylase activity in mouse development and ESC pluripotency regulation.
