Study on high density cultivation of red microalgae Porphyridium purpureum for Arachidonic acid production [PDF]
, 2016 非可再生化石资源的大量消耗导致了严重的环境问题和气候问题，这使得可再生且碳中性的生物质资源日益受到人们的关注。生物质可作为一种再生资源，在替代化石资源获取燃料、化学品和材料等领域具有广阔前景。其中，微藻具有将废弃物转化成生物燃料、食品、饲料原料以及其他高附加值生化产品的巨大潜能。海洋食物链中，微藻可作为多不饱和脂肪酸（PUFAs）的初级生产者，其种类繁多、含量丰富，具有诸多优点并且富产多种高附加值的生物活性物质。特别是近年来微藻已成为人们获取花生四烯酸（Arachidonicacid，ARA ...

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Shuitu Baochi Xuebao, 2020 喀斯特槽谷区在降雨过程中极易发生水土流失，这使得该区生态环境被破坏。以喀斯特槽谷区为研究对象，通过室内模拟其典型顺/逆层坡面特征及地下孔裂隙发育程度，利用人工降雨试验研究不同雨强条件下地表地下产流特征，从而揭示喀斯特槽谷区地表地下产流机制。结果表明：（1）喀斯特槽谷区地表地下产流受雨强影响，小雨强（30 mm/h）条件下地下产流量大于地表产流量，中雨强（60 mm/h）条件下地表产流量增大且裸坡条件下地表产流量大于地下产流量，大雨强（90 mm/h）条件下裸坡与顺层坡的地表产流量均大于地下产流量。（2 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

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，
