In eukaryotes, small RNAs (20–30 nt) derived from double stranded RNA precursors direct proteins to regulate chromatin function, transcription, RNA stability, and translation through sequence-targeted mechanisms termed RNA silencing. Two main categories of plant small RNAs, microRNAs (miRNAs) and short interfering RNAs (siRNAs), guide cleavage of mRNA and...

In order to test the function of specific genes or the impact of genetic variants on phenotype, genetic manipulation is required. The aim of the project is to assist with development and implementation of methods for genetic transformation of sunflower and monkeyflower, the two main study systems in the lab...

A major focus of our lab is identifying how genetic and phenotypic variation that has evolved among plant populations adapts plants to their local climates. Understanding how these adaptations to climate variation across space have evolved will help us understand mechanisms by which plants can evolve to cope with a...

Flowering and reproduction are highly regulated processes in composite plants like sunflower which produce disks that are clusters of many individual flowers. Environmental cues like light and temperature interact with the circadian clock regulate what time of the season buds first start to develop, and the same integration of internal...

During floral development, patterns of pigment are painted on to the petals of many plants, and these pigments often serve to attract and direct bee pollinators toward pollen and nectar rewards. We have found several natural variants affecting the nectar guide pigmentation patterns of the common monkeyflower in both the...

RNA-seq has been widely used in biological and medical research because of its capability to quantify transcriptome changes. Researchers usually use their impressions and experience to choose whether to analyze transcriptome changes in gene expression or alternative splicing levels. A more systematic way to determine whether to focus on...

Genome sequencing identifies a vast number of genetic variants. Predicting these variants’ molecular and clinical effects is one of the preeminent challenges in genetics. Accurate prediction of the impact of genetic variants improves our understanding of how genetic information yields molecular and cellular functions and is an essential step toward...

Proteins often fold into compact structural units, called domains. Protein domains are basic units of protein function and evolution. Delineating domain boundaries is a prerequisite for further analyses of protein structures. However, this process is largely a manual process and the accuracy of these computer programs is still not satisfactory...

The field of genome interpretation is essential for our understanding of human biology and the advancement of personalized medicine. However, the rapid accumulation of genomic data far exceeds our capacity for reliable interpretation. Consequently, the majority of variation discovered by next generation sequencing technologies is of unknown significance. These variants...

Plant's responses to external stimuli are highly dependent on the shuttling of intracellular signals to the nucleus, where the genome is reprogrammed to drive transcriptome changes to combat stress. A fundamentally important aspect of this process is the nuclear transport of stress-related signaling cargos mediated by nuclear transport receptors...

The nuclear envelope (NE) is structurally and functionally vital for eukaryotic cells, yet its protein constituents and their functions are poorly understood in plants. We combined subtractive proteomics and the proximity labeling technology-coupled with quantitative mass spectrometry to understand the landscape of NE membrane proteins in Arabidopsis and identified...

Filamentous fungi are hosts to pathogens such as viruses, bacteria, parasitic fungi, and grazing nematodes. Besides RNAi to protect fungal genomes from mycoviruses, a fungal inducible defense upon recognition of bacteria has yet to be fully described. Genes encoding nucleotide-binding domain Leucine-rich repeat-like (NLR-like) proteins are...

Plants have powerful defense mechanisms, which rely on an arsenal of plant immune receptors. Major classes of plant immune receptors include Receptor like kinases (RLKs), receptor like proteins (RLPs), and Nucleotide Binding Leucine Rich Repeat (NLR) proteins. On the population level, plant immune receptors provide plants with enough diversity to...

Plant diseases pose a significant threat to global agricultural crop production. Developing genetically modified plants with boosted disease resistance offers an economical and environmental solution. Plant immune receptors are naturally evolved resistance determinants that recognize target pathogen molecules to initiate defense responses. They have been widely used as transgenes. However...

General Description and Research Approach. Were heat waves or intense rainfall events common when you were growing up? Now, these events are common due to effects of climate change. These events include heatwaves, more severe and frequent rainstorms, increased wildfires and droughts. Recent Los Angeles fires are an example of...

Powdery mildew is an obligate biotrophic fungus that infects a broad variety of plants including plants of agronomic (e.g. grapevine) and ornamental (e.g. roses) import. It has lost many essential metabolic pathways and relies on the plant for these compounds. We are interested in figuring out the powdery mildew genes...
