most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. the expression of the gene glutathione-s-transferases (gst) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. gstf1 (the first phi gstfs class) gene expression patterns in the wheat cultivars mahuti ...

The effects of low root temperature on growth and root cell water transport were compared between wild-type Arabidopsis (Arabidopsis thaliana) and plants overexpressing plasma membrane intrinsic protein 1;4 (PIP1;4) and PIP2;5. Descending root temperature from 25°C to 10°C quickly reduced cell hydraulic conductivity (Lp) in wild-type plants but did not affect Lp in plants overexpressing PIP1;4 ...

Living walls are fast becoming a ubiquitous feature of modern living and widely implemented in commercial buildings both internal external environments. However, there several challenges associated with maintaining healthy plant growth on these water sensitive urban design systems. This experimental study an instrumented prototype-scale wall has found that is close relationship between the plan...

Photosynthesis of leaf discs from transgenic tobacco plants (Nicotiana tabacum) that express a chimeric gene that encodes chloroplast-localized Cu/Zn superoxide dismutase (SOD+) was protected from oxidative stress caused by exposure to high light intensity and low temperature. Under the same conditions, leaf discs of plants that did not express the pea SOD isoform (SOD-) had substantially lower...

The effects of low root temperature on growth and root cell water transport were compared between wild-type Arabidopsis (Arabidopsis thaliana) and plants overexpressing plasma membrane intrinsic protein 1;4 (PIP1;4) and PIP2;5. Descending root temperature from 25°C to 10°C quickly reduced cell hydraulic conductivity (L(p)) in wild-type plants but did not affect L(p) in plants overexpressing PIP...

Plant nitrogen (N) use is a key component of the N cycle in terrestrial ecosystems. The supply of N to plants affects community species composition and ecosystem processes such as photosynthesis and carbon (C) accumulation. However, the availabilities and relative importance of different N forms to plants are not well understood. While nitrate (NO3-) is a major N form used by plants worldwide, ...

Stem diseases of soybean with symptoms typical infection by Diaporthe spp. are common in the Northern USA. Information is limited, however, on characteristics associated pathogens. This study determined identity and symptomatic asymptomatic stems across diverse environments Minnesota. Plants stem canker, pod blight, plant dieback, as well plants, were sampled. Agar-based media PCR assays used t...

The effect in vivo of high nutrient levels of copper (240 micromolar) on the activity of different metalloenzymes containing Cu, Mn, Fe, and Zn, distributed in chloroplasts, peroxisomes, and mitochondria, was studied in leaves of two varieties of Pisum sativum L. plants with different sensitivity to copper. The metalloenzymes studied were: cytochrome c oxidase, Mn-superoxide dismutase (Mn-SOD) ...
