SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...

针对复杂地质条件下套管外载荷多变的特点,建立了基于遗传算法的套管柱优化设计方法。应用遗传算法理论,确定染色体编码方式及初始种群的产生方法,染色体评估函数及遗传操作,建立基于遗传算法的套管柱优化设计模型,从而克服了传统套管柱设计方法在复杂地质条件下套管柱强度设计中运算过程复杂,无法兼顾套管成本与风险因素的缺点。对普光气田某井套管柱进行的设计验证情况表明,该方法设计结果准确可靠,既提高了套管柱可靠性,又有利于降低成本。该项研究为复杂地质条件下优化套管柱设计提供了新的方法。

麋鹿是我国特有重点保护鹿科动物,是全球濒危物种保护的成功范例,具有重要的生态和文化价值。从乌邦寺建群到现今遍布世界的多个小种群来看,麋鹿的数量在逐步增长,生存力和繁殖力未发现有明显下降。麋鹿极小种群复壮造成其中性遗传多样性极度趋同,种群内个体之间的遗传相似系数极高,理论上影响其可持续发展的生存潜力。这些问题引起了学者和保护管理者的极大关注。本文从麋鹿的分类地位、遗传多样性研究概况等方面进行综述,为深入了解我国麋鹿进化地位、遗传多样性状况,加强我国麋鹿遗传资源的保护与管理,以及种群的健康可持续发展提供参考。

Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...

Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

Qilianshan National Park covers approximately 40% of core snow leopard habitat patches and 50% of movement corridors between patches. Including more of these important areas within the park boundaries should be considered, as the Qilianshan National Park sits at a pivotal juncture between critical snow leopard habitat in China and Mongolia, and may ...
