Mycorrhizal response in crop versus wild plants

Tracing the wild genetic stocks of crop plants.

A number of attempts have recently been made to identify the wild populations that form the founder germplasm stock of our crop plants (Huen et al. 1997; Molina-Cano et al. 1999; Ladizinsky 1999; Zhou et al. 1999; Badr et al. 2000). Some of these works were based mainly on comparative analyses and statistical treatments of genomic DNA polymorphism data (Huen et al. 1997; Molina-Cano et al. 1999...

Crop and medicinal plants proteomics in response to salt stress

Increasing of world population marks a serious need to create new crop cultivars and medicinal plants with high growth and production at any environmental situations. Among the environmental unfavorable conditions, salinity is the most widespread in the world. Crop production and growth severely decreases under salt stress; however, some crop cultivars show significant tolerance against the neg...

Amino Acid Uptake in Arbuscular Mycorrhizal Plants

We examined the extent to which arbuscular mycorrhizal (AM) fungi root improved the acquisition of simple organic nitrogen (ON) compounds by their host plants. In a greenhouse-based study, we used quantum dots (fluorescent nanoparticles) to assess uptake of each of the 20 proteinaceous amino acids by AM-colonized versus uncolonized plants. We found that AM colonization increased uptake of pheny...

Biofortification of Crop Plants

Salt resistant crop plants.

Soil salinity is a major constraint to agriculture. To improve salinity tolerance of crops, various traits can be incorporated, including ion exclusion, osmotic tolerance and tissue tolerance. We review the roles of a range of genes involved in salt tolerance traits. Different tissues and cells are adapted for specific and often diverse function, so it is important to express the genes in speci...
