Plants know where it hurts: root and shoot jasmonic acid induction elicit differential responses in Brassica oleracea.

Plants respond to herbivore attack by rapidly inducing defenses that are mainly regulated by jasmonic acid (JA).Due to the systemic nature of induced defenses, attack by root herbivores can also result in a shoot response and vice versa, causing interactions between above- and belowground herbivores.However, little is known about the molecular mech

Effect of zinc phosphate chemical conversion coating on corrosion behaviour of mild steel in alkaline medium: protection of rebars in reinforced concrete

We outline the ability of zinc phosphate coatings, obtained by chemical conversion, to protect mild steel rebars against localized corrosion, generated by chloride ions in alkaline media.The corrosion Gift Card resistance of coated steel, in comparison with uncoated rebars and coated and uncoated steel rebars embedded in mortar, were evaluated by o
