Nitric oxide is involved in phosphorus deficiency-induced cluster-root development and citrate exudation in white lupin
citrate exudation cluster roots nitric oxide phosphorus deficiency white lupin (Lupinus albus)
2015/2/5
White lupin (Lupinus albus) forms specialized cluster roots characterized by exudation of organic anions under phosphorus (P) deficiency. Here, the role of nitric oxide (NO) in P deficiency-induced cl...

Ethylene is an important plant gas hormone, and the amino acid Glu is emerging as a messenger molecule inplants.ToevaluatetheroleofethyleneandGluinseedgerminationandradiclegrowthundersaltstress, effec...
The ameliorative effec t of silicon on soybean see dlings grown in potassium- deficient medium
Antioxidant enzyme activities oxidative stress potassium deficiency silicon soybean Glycine max
2015/2/5
Background and Aims Crop yield and nutritional quality are significantly reduced when potassium (K) in soil is deficient. As a beneficial element for plants, silicon (Si) is effective in alleviating t...
Aluminium-induced inhibition of root elongation in Arabidopsis is mediated by ethylene and auxin
Aluminium toxicity Arabidopsis thaliana auxin polar transport ethylene root elongation
2015/2/5
Aluminium (Al) is phytotoxic when solubilized into Al3+ in acidic soils. One of the earliest and distinct symptoms of Al3+ toxicity is inhibition of root elongation. To decipher the mechanism by which...
Ethylene is involved in nitrate-dependent root growth and branching in Arabidopsis thaliana
Arabidopsis thaliana ethylene production lateral root development nitrate concentration nitrate transporters
2015/2/5
Here, we investigated the role of ethylene in high nitrate-induced change in root development in Arabidopsis thaliana using wild types and mutants defective in ethylene signaling (etr1, ein2) and nitr...
Phosphorus deficiency-induced reduction in root hydraulic conductivity in Medicago falcata is associated with ethylene production
Phosphorus deficiency Root hydraulic conductivity Ethylene production Aquaporins Medicago falcata L
2015/2/5
Plants grown in phosphorus-deficient solutions often exhibit disruption of water transport due to reduction in root hydraulic conductivity (Lpr) and enhanced ethylene production. To uncover the relati...
Nitric Oxide is Involved in Nitrate-induced Inhibition of Root Elongation in Zea mays
Nitrate supply nitric oxide (NO) IAA root elongation maize Zea mays
2015/2/5
Background and Aims Root growth and development are closely dependent upon nitrate supply in the growth medium. To unravel the mechanism underlying dependence of root growth on nitrate, an examination...
Nutrient loading of developing seeds
membrane transport nutrients phloem transport remobilisation seeds symplasmic transport
2015/2/5
Interest in nutrient loading of seeds is fuelled by its central importance to plant reproductive success and human nutrition. Rates ofnutrient loading, imported through the phloem, are regulated by tr...
Glucose-induced inhibition of seed germination in Lotus japonicus is alleviated by nitric oxide and spermine
Glucose Lotus japonicus Nitric oxide Seed germination
2015/2/5
Seed germination is sensitive to glucose (Glc), nitric oxide (NO) and polyamine (PA). To elucidate whether cross-talk among Glc, NO and PAs occurs in mediation of seed germination, effects of Glc, NO ...
Synergistic effect of benzolinone with IBA and fungicides on the vegetative propagation of ornamental plants, park, and fruit woody species
benzolinone indole-3-butyric acid (IBA) captan Trichoderma harzianum vegetative propagation ornamental plants park and fruit woody species
2015/1/20
A study was made of the stimulating effect of benzolinone (3-benzyloxycarbonyl-methyl)-2-benzothiazolinone in powder form (P) and its mixture with indole butyric acid (IBA), the biofungicide Supresivi...
Regional Comparison of Overwintering Mortality, Fecundity, and Virulence in the Hemlock Woolly Adelgid
Adelges tsugae Fiorinia externa virulence
2015/1/4
Throughout the eastern United States, the spread of the hemlock woolly adelgid, Adelges tsugae Annand, has caused high mortality of eastern hemlocks Tsuga canadensis (L.). We recorded overwintering su...
负密度制约和生境过滤是解释森林群落物种共存和生物多样性维持机制的重要假说.已有大量研究表明，负密度制约通过优势物种的种内竞争及近缘种之间的种间竞争、个体间病菌传播等过程为非优势物种及非亲缘种提供生存空间，从而使局域群落的系统发育α多样性随时间的推移而增加;由于生境过滤的作用，特定的生境选择亲缘关系相近的物种，因而随着时间的推移，同一生境内群落间的系统发育β多样性会降低.前人的研究主要集中于利用负密...
外源激素对棉花前期生长发育的影响

以鲁棉28为材料，在大田条件下设置吲哚乙酸（IAA）5 mg·L-1、10 mg·L-1，6-苄基腺嘌呤（6-BA）50 mg·L-1、100 mg·L-1，赤霉素（GA）20 mg·L-1、50 mg·L-1 6个不同浓度水溶液处理，以清水为对照，在苗期至蕾期叶面喷施3次，研究外源激素对棉花前期生长与发育的影响。结果表明，外源激素处理后，棉花主茎纵向生长速度缓于对照，茎粗大于对照。50 mg·L...
中国双季稻种植分布的年代际动态
双季稻 种植分布 年代际 动态
2013/8/9
定量描述气候变化影响下水稻种植分布变化可为优化水稻生产布局及制定应对气候变化政策提供依据. 基于最大熵方法建立的双季稻种植分布与气候的关系模型, 本文研究了1961～2010年我国双季稻种植分布变化. 结果表明: 我国双季稻种植分布及其气候适宜性存在年代际变化. 低适宜等级以上总适宜区面积, 在20世纪60年代最高, 70年代到21世纪前10年呈先增后减的特点; 低适宜区面积呈减少趋势, 反映双季...
