Collective efforts of several laboratories in the past two decades have resulted in the development of various methods for Agrobacterium tumefaciens–mediated transformation of Arabidopsis thaliana. Among these, the floral dip method is the most facile protocol and widely used for producing transgenic Arabidopsis plants. In this method, transformation of female gametes is accomplished by simply ...

PALAVRAS-CHAVE Glycine max L. Merrill Temperatura foliar Déficit hídrico Perda de água. ABSTRACT: There are few studies in the specific literature on the use of cover materials to control evaporation in drought-stressed plants grown in pots under greenhouse conditions. The use of these materials is of great importance to ensure that water loss occurs only through transpiration. Thus this study ...

Members of the Tagetes genus include important floricultural (cut-flower) and ornamental (pot and garden) crops, as well as plants of medicinal and ethno-pharmacological interest. Despite the use of many of these plants in the extraction of important secondary metabolites and essential oils, the greatest biotechnological emphasis has been on their in vitro tissue culture and micropropagation. F...

Arbuscular mycorrhizal fungi are the most widespread root fungal symbionts, forming associations with the vast majority of plant species. Ectomycorrhizal development alters gene expression in plant symbionts. In this work we examined the effect of arbuscular mycorrhizal fungi spores on the growth and development of Brassica and on the expression of BnMT2 in winter rape. In a pot experiment, rap...

This study aimed to investigate the effect of nano-Ca fertilizer on nitrogen uptake, use efficiency and determine best calcium form dose for mango. A pot experiment was conducted using two year old mango seedlings (cv. Zebda). The pots were filled with sandy soil (8 kg per pot) one seedling transplanted into each pot. Four treatments including nano-Ca, convention Ca, application foliar have bee...

Plants face many antagonistic interactions that occur sequentially. Often, plants employ defense strategies in response to the initial damage that are highly specific and can affect interactions with subsequent antagonists. In addition to herbivores and pathogens, plants face attacks by parasitic plants, but we know little about how prior herbivory compared to prior parasite attachment affects ...

Holoparasites are nonphotosynthetic plants that acquire all resources from hosts. The holoparasite Cuscuta gronovii is native to much of the US with a broad host range including Verbesina alternifolia, an understory perennial. Both species grow in moderate to moist soils and occur in habitats that may experience prolonged or episodic drought. We applied the Wise-Abrahamson Limiting Resource Mod...

A greenhouse pot experiment was carried out to evaluate the efficiency of arsenic phytoextraction by the fern Pteris vittata growing in arsenic-contaminated soil, with or without the addition of selected rhizobacteria isolated from the polluted site. The bacterial strains were selected for arsenic resistance, the ability to reduce arsenate to arsenite, and the ability to promote plant growth. P...

d-coder is a fertilizer with a new slow-release mechanism consisting of an organo-mineral matrix that releases the nutrients only in the presence of growing plants. pot and field experiments were carried out to study the release pattern of n from d-coder. the experiments included grown and bare soil plots. the fertilizer treatments were d-coder, ammonium nitrate (anpreplant), and the control. a...

An experiment was conducted to assess whether KOH applied as a foliar spray could mitigate the adverse effects of salt stress on plant growth and yield of sunflower plants. For this purpose, KOH @ 0, 0.5, 1.0, 1.5 and 2.0% was applied as a foliar spray to salt stressed and non-stressed sunflower plants. Foliar spray of KOH increased the growth and yield under non-stress and salt stressed condit...
