Increasing pea (Pisum sativum) seed nutritional value and particularly seed protein content, while maintaining yield, is an important challenge for further development of this crop. Seed protein content and yield are complex and unstable traits, integrating all the processes occurring during the plant life cycle. During filling, seeds are the main sink to which assimilates are preferentially al...

1. A fundamental trade-off among vascular plants between traits inferring rapid resource acquisition and those leading to conservation of resources has now been accepted broadly, but is based on empirical data with a strong bias toward leaf traits. Here we test whether interspecific variation in traits of different plant organs obeys this same trade-off and whether within-plant trade-offs are c...

Drought limits light harvesting, resulting in lower plant growth and reproduction. One trait important for plant drought response is water-use efficiency (WUE). We investigated (1) how the joint genetic architecture of WUE, reproductive characters, and vegetative traits changed across drought and well-watered conditions, (2) whether traits with distinct developmental bases (e.g. leaf gas exchan...

Plants use their roots to forage for nutrients in heterogeneous soil environments, but different plant species vastly differ in the intensity of foraging they perform. This diversity suggests the existence of constraints on foraging at the species level. We therefore examined the relationships between the intensity of root foraging and plant body traits across species in order to estimate the d...

thrips species injurious to grapes are known as pests in vineyards all over the world and belong to the main pests of grapes in west azarbaijan, iran. in this study, thrips species occurring in west azarbaijan vineyards were identified and the predominant species documented according to their relative abundance at different growth stages. the seasonal abundance of predominant species was invest...

Introduction: Vinca rosea, an important medicinal plant, is well-known for its anticancer properties especially against breast cancer. In this study, we compared the cytotoxic effects of methanolic extracts of the vegetative (young and old leaves) and reproductive (flowers) organs of this plant on a human squamous cell carcinoma using MTT assay. Methods: The cytotoxic effects of Vinca rosea'...

With the exception of barley and rice, little is known about the existence of hemoglobins (Hbs) in cereals. This work reports the cloning and analysis of hb genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis). Coding sequences of maize and teosinte hb genes (hbm and hbt, respectively) are highly similar to each other and are interrupted by three introns located at ide...
