Trade-offs between constitutive and induced defences drive geographical and climatic clines in pine chemical defences.
There is increasing evidence that geographic and climatic clines drive the patterns of plant defence allocation and defensive strategies. We quantified early growth rate and both constitutive and inducible chemical defences of 18 Pinaceae species in a common greenhouse environment and assessed their defensive allocation with respect to each species' range across climatic gradients spanning 31° ...
متن کاملSimple Growth Patterns Can Create Complex Trajectories for the Ontogeny of Constitutive Chemical Defences in Seaweeds
All of the theory and most of the data on the ecology and evolution of chemical defences derive from terrestrial plants, which have considerable capacity for internal movement of resources. In contrast, most macroalgae--seaweeds--have no or very limited capacity for resource translocation, meaning that trade-offs between growth and defence, for example, should be localised rather than systemic....
متن کاملUnusual P450 reactions in plant secondary metabolism.
Plant cytochromes P450 (P450s) participate in a variety of biochemical pathways to produce a vast diversity of plant natural products. The number of P450 genes in plant genomes is estimated to be up to 1% of the total gene annotations of each plant species, implying that plants are huge sources for various P450-dependent reactions. Plant P450s catalyze a wide variety of monooxygenation/hydroxyl...
متن کاملDissecting a complex chemical stress: chemogenomic profiling of plant hydrolysates
The efficient production of biofuels from cellulosic feedstocks will require the efficient fermentation of the sugars in hydrolyzed plant material. Unfortunately, plant hydrolysates also contain many compounds that inhibit microbial growth and fermentation. We used DNA-barcoded mutant libraries to identify genes that are important for hydrolysate tolerance in both Zymomonas mobilis (44 genes) a...
متن کاملHerbivore-induced, indirect plant defences.
Indirect responses are defensive strategies by which plants attract natural enemies of their herbivores that act as plant defending agents. Such defences can be either constitutively expressed or induced by the combined action of mechanical damage and low- or high-molecular-weight elicitors from the attacking herbivore. Here, we focus on two induced indirect defences, namely the de novo product...
