Mutant series: Argonaute 1 (AGO1)

Image
ARGONAUTE (AGO) protein family was named first as PAZ proteins. "PAZ" represents p ELEMENT-INDUCED WIMPY TESTS ( P IWI) from  Drosophila , ARGONAUTE1  ( A GO1) and  ZWILLE (ZIL) from  Arabidopsis thaliana . All these proteins were discovered initially, and they shared a common domain.    Later, it has been found that DICER proteins also contain PAZ domain. To distinguish them from DICER proteins, then it was renamed as PPD ( P AZ P IWI D OMAINS) proteins. Because of this renaming, it clearly distinguished between ARGONAUTE and DICER based on the presence of domains. For ARGONAUTE, PIWI domain is unique.    From the functional analysis, it had been shown that few PPD proteins has RNaseH-like activity, cleaves targeted ssRNA (single-stranded RNA). To make an adjustment with the DICER for naming, they named as SLICER. It's a cool name, isn't it? Eric Lander called it "enzymatic king-fu"!  However, problems remained. ...

For plant scientists, two most popular plant specific journals are - The Plant Cell & Plant Physiology . Interestingly, both of these journals are publication venture of A merican S ociety of P lant B iologists (ASPB) . As a result, massive submission trafficking is going on through these journals. Let's consider few facts about these journals. Both of these journals have monthly issues. Total 24 issues. Each issue has 8-10 or maximum 12 research article. Annually approximately 250 research articles are published. On the other side, the number of lab working with only model plant Arabidopsis is several thousand. Just think about, what is expecting number if we consider all plant science lab around the globe. This facts and figures clearly illustrate that top 5% lab can publish up to that mark. But, if any manuscripts bounced back from ASPB journal doesn't mean that it's not worthy enough to be published in a respected journal. Rather than it means that scopes are les...

Mutant series: LORD OF THE RINGS 1 (LOTR1)

Image
I'm a huge fan of Niko Geldner and Casparian strip story. A new paper came up recently in Current Biology which is like another bead of that string.  Rather than describing the whole story, this post will focus only about the newly identified gene reported in this paper. In a broader sense, "Mutant series" is going to be lot more fun to know about the story behind the naming of mutants and science as well as.  Figure 1: Graphical abstract of the paper Nutrients pass through two ways - apoplastic and symplastic pathway - to enter the root system. Formation of Casparian strips and suberin lamellae limits the free diffusion of nutrients and harmful substances.  In root, endodermis cells have Casparian strips and kind of act as a belt around the vascular tissues to control nutrient entry.  Casparian strips are ring-like lignin polymers deposited in the middle of anticlinal cell walls between endodermal cells and fill the gap between them. Suberin ...

Plant Biology Highlights: Cell Articles 2016

Plant biologists mostly put their focus on plant specific journals such as The Plant Cell, Plant Physiology, Nature Plant, The Plant Journal, Journal of Experimental Botany, Plant, Cell & Physiology, Molecular plant etc. Apart from these journals, striking findings about plant sciences are also published in Science, Nature, Cell, PNAS etc. This is the last month of 2016. I was going through major journals and trying to find out what I missed. Definitely I missed so many which are not directly linked to my research or study. So, I have decided to compile all plant biology related articles from major non-plant specific journals and summarize. In this post, I've summarized from Cell. Cryptochromes interact directly with PIFs to control plant growth in limited blue light    Sun-loving plants have the ability to detect and avoid shading through sensing of both blue and red light wavelengths. Higher plant cryptochromes (CRYs) control how plants modulate growth in res...

In this paper, Xuan  et al.  showed that programmed cell death sets the cours...
