Plant direct author stories

Our journal's mission is to help our community by giving them an easier, faster way to get all their science out. Authors are choosing to publish in Plant Direct for different reasons—whether it is to add their first publication to their CV, to share initial findings that could be valu‐ able to others working on similar research, or their paper has been referred from Plant Cell, Plant Physiology or The Plant Journal, and they agreed to transfer their manuscript and the reviews to save time. We are excited to share the experiences of three investigators who have recently published in Plant Direct. Thank you Alexis Maizel, Elizabeth Haswell, and Joshua R. Widhalm for sharing your author stories with us and the Plant Direct community! We hope their sto‐ ries inspire you and that you consider Plant Direct is as the right home for your next paper.


What does your laboratory work on?
My laboratory studies the mechanisms of lateral root morphogenesis in Arabidopsis. We combine molecular genetics, cell biology, and microscopy to understand how these new roots are robustly formed.

Tell us about the key findings from your recent article in Plant Direct
This article links to another interest of my laboratory: The role played the trans-acting small interfering RNAs (ta-siRNAs) in controlling root growth. The production of such ta-siRNAs from their TAS3 precursors is triggered by the microRNA miR390. In this article, we report that miR390 is expressed in the transit-amplifying compartment of the root meristem where it modulates response to exogenous auxin. The expression of miR390 in this region of the meristem depends on ARF5/ MONOPTEROUS.

How did you get the idea to do this study?
Comparatively, we know a lot about what miRNAs control but little about how they are themselves transcriptionally controlled.
Nothing was known about the cis-regulatory elements that govern the precise expression of miR390 in the root meristem and the lateral root primordia. We decided to map the promoter to test whether distinct enhancers could be identified.
What do you plan to do next, based on these current findings?
Better characterize the gene regulatory network at play in the basal meristem.

How was your experience with publishing in Plant Direct?
The manuscript had been submitted to The Plant Cell. The postreview decision made clear that although solid, the story would be a better fit for Plant Direct. The transfer of the manuscript and reviews was seamless and a decision to publish reached within days. It was a very efficient and professional process.

What does your laboratory work on?
My group studies the cellular and molecular mechanisms by which plants sense and response to mechanical stimuli. In particular, we focus on a class of molecular mechanoreceptors called mechanosensitive ion channels.

Tell us about the key findings from your recent article in Plant Direct
This project was meant to be a straightforward study of genetic and protein-protein interactions between three mechanosensitive ion channels from Arabidopsis thaliana, two that localize to the chloroplast, and one that localizes to the mitochondria. Things turned out to be a bit more complicated than we thought, and it turns out that loss of the mitochondrial channel exacerbates some phenotypes associated with loss of the chloroplast channels; but ameliorates others.

Why did you choose to publish in Plant Direct?
For the most part, this paper comprises the senior thesis of Wash U undergraduate Josephine Lee. She worked in the laboratory for a few semesters for credit, and in the summer of 2015 was awarded an ASPB SURF to continue the project. The following semester she wrote everything up for her senior thesis. When I saw it, I realized that she'd collected some interesting results, and done so exceptionally carefully. We only had to make a few small changes to prepare her figures for publication! Josephine was really invested in published her work, both to share it with the field and to have a publication on her CV when she applies to graduate school. However, the complicated nature of her results would have made it difficult to publish in many journals without a lot of additional study. We chose Plant Direct for its focus on sound science rather than novelty or perceived impact.

Tell us about the key findings from your recent article in Plant Direct
We report-to the best of our knowledge-the first observation of specialized quinones in nectar and their antifungal activities against common nectar fungi. The species we studied, Impatiens glandulifera, is known to produce specialized quinones. Interestingly, one of these compounds, 2-methoxy-1,4-naphthoquinone, is considered an allelochemical that has contributed the invasion success of I. glandulifera in certain parts of Europe and North America. The significance of our study is that we have uncovered evidence to suggest that quinones Michigan where I. glandulifera is on the invasive species watchlist.
As my laboratory becomes more established, I will look for opportunities and funding to study existing populations in other areas in order to get at some of the questions that have emerged from our work.

Why did you choose to publish in Plant Direct?
As I alluded to above, we've had to move on from this project for now. We obviously didn't finish the whole story yet, but I felt we did complete a sound study and made noteworthy observations that could be valuable to others working with I. glandulifera, or with allelopathy or nectar chemistry more broadly. Rather than sit on our findings until we could revisit the work, I decided to submit  also particularly attractive because it is a peer-reviewed journal.
As an Assistant Professor I need to publish, and it is imperative that my work be critically evaluated by others in the community.
So, for all these reasons I decided that Plant Direct was the right forum to disseminate our work.
