Central Roles and Regulatory Mechanisms of Dual-Specificity MAPK Phosphatases in Developmental and Stress Signaling

Mitogen-Activated Protein Kinase (MAPK) cascades are conserved signaling modules that integrate multiple signaling pathways.One level of control on the activity of MAPKs is through their negative regulators, MAPK phosphatases (MKPs).Therefore, MKPs also play an integrative role for plants responding to diverse environmental stimulus; but the mechan

Moth resistance of armored-layer sunfi ower seeds

Sunflower varieties having plants with armored-layer seeds resulted in a high reduction of seed damage caused by larval feeding of the sunflower moth, Homoeosoma Accessories electel-lum (Hulst).Several sunflower lines were significantly more resistant to seed damage when the plants had armored-layer seeds than when the same lines had non-armored-la

Effectiveness of different databases in identifying studies for systematic reviews: experience from the WHO systematic review of maternal morbidity and mortality

Abstract Background Failure to be comprehensive can distort the results of a systematic review.Conversely, extensive searches may yield unmanageable number of citations of which only few may be relevant.Knowledge of usefulness of each source of information may help to tailor search strategies in systematic reviews.Methods We conducted a systematic
