Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

open access: yesAdvanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Linking Plant Metabolomics with Fungal Functional Dynamics Reveals a Noncanonical S‐R‐C Adaptive Trajectory

open access: yesAdvanced Science, EarlyView.
Using field‐based holo‐omics, we demonstrate that developmental shifts in sorghum leaf metabolomes drive a noncanonical fungal succession from stress tolerators (S) through ruderals (R) to competitors (C). Antifungal metabolites in young leaves select for S strategists with expanded genomes, transient maltose pulses during flowering favor fast‐growing ...

Genetic Analysis of Resistance to Puccinia triticina Erikss. In Triticum spelta L.

open access: yesFrontiers in Bioscience-Scholar
Background: Leaf rust caused by Puccinia triticina Erikss. is a widely distributed wheat (Triticum aestivum L.) disease. Using wild relatives, such as Triticum spelta L., as a source of desirable traits represents a good strategy for ...

Productivity convergence in the European regional agricultures. Determinants of its evolution [PDF]

open access: yes
The aim of this study is to analyse the evolution of the European regional agricultural productivity in terms of convergence. The initial hypothesis is that, in spite of the integration process, the agricultural productivity does not converge to the same

Agricultural productivity in past societies: toward an empirically informed model for testing cultural evolutionary hypotheses [PDF]

open access: yes, 2015
Agricultural productivity, and its variation in space and time, plays a fundamental role in many theories of human social evolution. However, we often lack systematic information about the productivity of past agricultural systems on a scale large enough

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...
