Studies on Arbuscular Mycorrhiza infection to Mangrove Plants in Fujian [PDF]

open access: yes, 2012
2010年5月和12月,对福建沿海3个红树林生长区(洛阳江、九龙江口、漳江口)的红树林植物丛枝菌根(AM)侵染状况进行研究。结果表明:(1)红树林生长区中6种植物根内均发现AMf侵染结构,其中桐花树、秋茄、鱼藤和芦苇的丛枝为AruM(疆南星)型;(2)6种植物的丛枝菌根侵染率差异较大,老鼠簕的侵染率最高,鱼藤最低;(3)桐花树和秋茄的丛枝菌根侵染率呈显著差异,而其在不同生长区之间无差异;(4)桐花树和秋茄的丛枝菌根侵染率在不同时间呈显著差异,而钝草的丛枝菌根侵染率在不同时间的差异不显著。To study

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.
Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

菌剂配施有机肥下植物-土壤-微生物生态化学计量特征及内稳性——以内蒙矿区排土场中药复垦模式为例

open access: yesShuitu Baochi Xuebao, 2023
生态化学计量学是研究生态系统与多重化学元素平衡的有效方法,明确不同施肥制度对植物-土壤-微生物连续体碳、氮、磷含量及其生态化学计量比的影响,可为揭示生态系统养分循环、实现矿山复垦农业系统元素平衡及可持续发展提供参考依据。以武家塔露天煤矿排土场复垦地为研究对象,设置微生物菌剂配施不同有机肥(A1B0、A2B0、A3B0、A1B1、A2B1、A3B1) 6个施肥处理,结合苦参的种植,研究其植物-土壤-微生物碳氮磷特征及内稳性。结果表明:(1)与单施有机肥相比,有机肥配施微生物菌剂对茎叶磷 ...

Effects of domestic sewage effluents on the growth and physiological characteristics of Catharanthus roseus [PDF]

open access: yes, 2005
利用不同稀释倍数的生活污水(污水∶清水,V/V,分别为1∶0;1∶1;1∶2;0∶1)浇灌长春花结果表明,与清水灌溉相比,污灌处理土壤NH4+-N含量由59.01mg/kg提高到64.22~65.89mg/kg,NO3--N含量由2.69mg/kg提高到3.03~4.54mg/kg,速效磷含量由32.29mg/kg提高到37.40~42.41mg/kg;增加了土壤酶活性,其中土壤过氧化氢酶、脲酶及蛋白酶活性分别比对照提高10.76%~23.32%、33.41%~103.69%和31.82%~131.82%

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.
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 ...

土壤因子对西藏高原草地植物AM真菌的影响

open access: yesShuitu Baochi Xuebao, 2004
于西藏高原中部地区就土壤因子对草地植物AM真菌的影响进行的研究表明:AM真菌孢子密度与菌根侵染率、菌根侵染强度无相关性;土壤质地对AM真菌孢子密度的影响明显大于土壤类型,壤土、粉砂土中AM真菌对植物根系的侵染率高于砂壤土;土壤pH与植物根围土壤孢子密度、菌根侵染率分别呈显著正相关和正相关,与菌根侵染强度则呈负相关;土壤有机质与AM真菌孢子密度呈负相关,菌根侵染效果则随土壤有机质含量的增加而提高;高磷土壤环境对AM真菌产孢和侵染均具不同程度的抑制作用,其中植物菌根侵染率随土壤有效磷含量的提高而呈显著下降 ...

Experimentally researching the root exudates of mangroves—pollution ecological effects of heavy metals stress [PDF]

open access: yes, 2008
本研究报告一是考察了3种红树植物-木榄、秋茄和白骨壤-根系分泌物中的糖类及其他多羟基化合物的种类,以及季节变化(夏季和冬季)对它们的影响。结论如下:1)3种红树植物根系分泌物中的多羟基化合物与物种和季节相关,与短期的年龄变化无关;其中一些还与植物种类、亲缘关系有关。2)冬季有更多种类的多羟基化合物种类。3)不同季节中的糖类物质的化学形态是不同的,夏季以直链状、冬季以环状存在。4)首次发现根系分泌物中存在肌醇,并有一种以上的异构体,其中仅有一种异构体出现于所有3种红树植物的夏季和冬季样品中。其次 ...

Legacies of consecutive summer droughts on soil‐borne plant parasitic protists (Oomycota: Stramenopila and Phytomyxea: Rhizaria) and protistan consumers (Cercozoa: Rhizaria) along an experimental plant diversity gradient

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2010-2024, February 2026.
Summary Increasing frequencies of severe summer droughts and plant diversity loss disrupt ecosystem functioning and stability of European grasslands. Understanding how these factors interact with pathogens is crucial. We investigated the effects of plant diversity and repeated summer drought on soil‐borne parasites within a grassland biodiversity ...
