A feeling for the organism: Genetics, development, and evolution of phenotypic diversity and novelty in monkeyflowers

The wildflower genus Mimulus (monkeyflowers) has been widely recognized as a classic ecological and evolutionary model system in studying local adaptation, speciation, plant-pollinator interactions, and species range limits. What is less known, however, is that this system also holds great promise for detailed molecular dissections of the genetic bases and developmental mechanisms of pattern formation, phenotypic diversification, and the origin of novel phenotypes.

A Day in the Life of a Cyanobacterium: integrating temporal and environmental information

Cells of diverse organisms, from cyanobacteria to humans, execute temporal programs that are driven by circadian oscillators. The circadian clock of the cyanobacterium Synechococcus elongatus is a discrete nanomachine comprising three proteins – KaiA, KaiB, and KaiC – which interact progressively to set up the timekeeping mechanism, and two kinases whose activities are altered by engaging the Kai oscillator.

CANCELED: Plant-pollinator interactions and movement in the context of global change

More than 60% of earth’s terrestrial surface is managed by humans as agriculture, pasture, or urbanized areas, and land conversion continues to be the primary driver of global biodiversity loss. Despite this, little is known about the impacts of land management on multi-species interactions, gene flow, and ecosystem function. The Jha Lab investigates ecological and evolutionary processes from genes to landscapes, to quantify global change impacts on plant-animal interactions, movement ecology, and the provisioning of ecosystem services.
