Identification of Rice Dwarf Mutant and Fine Mapping of mhd1 Gene [PDF]
, 2016 株高是水稻株型重要的组成因子，直接关系到水稻的产量，株高过高易引起植株倒伏导致减产，适当矮化则可以达到抗倒、增产的目的。虽然目前已经鉴定不少与水稻矮秆相关的基因，但是能够在生产上实际应用的矮秆主基因仍以sd1为主。因此，寻找和创造能在生产上利用的矮秆种质资源以及研究矮化相关机制具有重要的理论和实践意义。 本研究的材料源于籼稻品种闽恢3301经EMS诱变产生的小粒矮秆突变体，暂命名为mhd1（Minhui3301dwarf1）。mhd1表现出多个异常表型，包括植株矮化、叶片直立变宽、叶色深绿、穗和谷粒较小，

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

The research of the detection of thalassaemia multiple mutations by next-generation sequencing technology [PDF]
, 2015 地中海贫血又称珠蛋白生成障碍性贫血，早期的病例来自地中海地区，故称为地中海贫血，是世界范围内影响最大的单基因病之一，遵循孟德尔遗传定律。该病是由珠蛋白基因的缺失或点突变所致，根据其变异的肽链可分为α地贫和β地贫。由于其基因缺陷的复杂、多样，使缺乏的珠蛋白链类型、数量、临床症状变异较大。临床上对中、重度地中海贫血无行之有效的治疗方法，给社会、家庭、个人带来了沉重的经济及精神负担。故有效检出地中海贫血患者、进行婚前孕前指导、产前诊断、避免地中海贫血患儿的出生，有着极其重要的社会意义 ...

Conservation Biology, EarlyView.Abstract Wildlife reintroductions are socioecological processes entailing the intentional movement of organisms by people. In animal reintroductions, there is growing recognition of the importance of human dimensions and efforts to integrate these into reintroduction projects. To conceptually reframe reintroductions as processes of renewed coexistence (

Function of SAV6 in Maintenance of Genome Integrity and Root Development in Arabidopsis [PDF]
, 2015 flap核酸内切酶FEN1（flapendonuclease1）是RAD2家族的一种能够识别特异底物结构的核酶。FEN1具有三种酶活性：flap核酸内切酶（FlapEndonuclease,FEN）活性、5’核酸外切酶（5’-Exonuclease,EXO）活性和缺口依赖的核酸内切酶（GapEndonuclease,GEN）活性，在DNA复制、修复以及维持端粒稳定性等方面发挥着重要作用。人们对FEN1在哺乳动物、酵母中的功能已经有了深入了解，但是拟南芥中尚无相关研究 ...

Mechanistic study of TREM2 mutations in increasing the risk of neurodegenerative diseases [PDF]
, 2016 2型髓系细胞触发受体（Triggeringreceptorexpressedonmyeliodcells2，TREM2）是中枢神经系统（centralnervoussystem，CNS）中主要表达于小胶质细胞表面并参与机体固有免疫的一种受体蛋白，与其接头蛋白酪氨酸激酶结合蛋白（DNAXactivatingproteinof12kDa，DAP12）形成TREM2/DAP12复合物，从而调节小胶质细胞中的炎症反应和吞噬功能。TREM2属于Ⅰ型跨膜蛋白，其胞外段经过蛋白酶切割后产生可溶形式TREM2 ...

From Clueless to Confident: How ChatGPT Transforms Academic Writing in Chinese as a Second Language
International Journal of Applied Linguistics, EarlyView.ABSTRACT Generative artificial intelligence (GenAI) has demonstrated its potential to enhance the quality of second‐language (L2) academic writing. This study used a qualitative approach comprising analysis of ChatGPT usage‐history screenshots, written assignments, and semi‐structured interview data on students’ use of GenAI in their L2 Chinese ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.
