Soil arsenic (As) pollution in mining areas have seriously affected the surrounding environment and human health. To explore degree of soil As contamination phytoremediation strategies, a study was undertaken to identify suitable native plants for area. Geo-accumulation index potential ecological risk were sed assess degree. content dominant analyzed by enrichment coefficient. The results show ...

Anaerobic nitrogen-fixing consortia consisting of N2-fixing clostridia and diverse nondiazotrophic bacteria were previously isolated from various gramineous plants (K. Minamisawa, K. Nishioka, T. Miyaki, B. Ye, T. Miyamoto, M. You, A. Saito, M. Saito, W. Barraquio, N. Teaumroong, T. Sein, and T. Tadashi, Appl. Environ. Microbiol. 70:3096-3102, 2004). For this work, clostridial populations and t...

Mutual relationship between endophytic fungi and some gramineuos plants is one of the recently known host-microbe interactions. Endophytic fungi are classified in class Ascomycetes, order Hypocreales, tribe Balansieae and mostly genus Neotyphodium. They are transferred into the progeny via maternal stock and have many benificial effects to their host plants, such as resistance to pests and dise...

Under waterlogged conditions, roots of gramineous plants form lysigenous aerenchyma (internal gas spaces) by inducing the death of cortical cells. Rice (Oryza sativa) roots induce aerenchyma formation through ethylene- and reactive oxygen species (ROS)-mediated signaling. Metallothionein (MT) is a small, cysteine-rich protein that acts as a ROS scavenger. In rice roots, the expression of MT1a, ...

The uptake of mercury vapor by six gramineous plant species was compared under uniform conditions using a whole-plant chamber and (203)Hg-labeled mercury at a low atmospheric concentration. Mean Hg uptake by leaves of the C(3) species oats (Avena sativa), barley (Hordeum vulgare), and wheat (Triticum aestivum) was 5 times greater than that by leaves of the C(4) species corn (Zea mays), sorghum ...

Bidirectional promoters, which show great application potential in genetic improvement of plants, have aroused great research interest recently. However, most bidirectional promoters were cloned individually in the studies of single genes. Here, we initiatively combined RNA-seq data and cDNA microarray data to discover the potential bidirectional promoters in rice genome. Based on the expressio...
