What does this picture highlight? Difrerent life stages of cardamine? How much time does this process take?

How easy or difficult it is to take such amazing pictures?

What kind of studies can be done with these flowering cardamine?

@Priti_Kanade please hell us from basic like what should be our long term objective and also how we differentiate between various species of cardamine as well

🔹Cardamine is close relative of plant model _Arabidopsis thaliana_  
🔹They both differ in few characteristics  
🔹Arabidopsis has simple leaves, whereas Cardamine has compound ones  
🔹Floral dip method enables us to make transgenic Cardamine having simple leaves  
🔹To perform this, we need a better understanding about lifecycle of Cardamine  
This image gives an idea about progression of green floral bud to seed pod 😇

Only this (“…enables us to make transgenic Cardamine having simple leaves”) can be done through floral dip?😟@Priti_Kanade

# A rapid and robust method of identifying transformed _Arabidopsis thaliana_ seedlings following floral dip transformation

_Arabidopsis_ transformation mediated by vacuum infiltration of inflorescences with an _Agrobacterium_ suspension was first introduced by Bechtold et al. [[1](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1636043/#B1)]. This method has been widely used in preference to tissue culture techniques as it directly produces transformed seed and negates lengthy and complicated tissue culturing procedures. This transformation method was further modified by Clough and Bent [[2](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1636043/#B2)] who demonstrated that the method was just as effective without vacuum infiltration. Immersion of _Arabidopsis_ inflorescences in a suspension of _Agrobacterium_ , with surfactant, was sufficient to generate transformed seed. This method remains the method of choice for _Arabidopsis_ transformation. Selection of transformants from non-tranformants requires the presence of a marker, usually in the form of either antibiotic or herbicide resistance. Selection for resistance, for example to kanamycin, typically takes 7–10 d following germination [[1](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1636043/#B1),[2](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1636043/#B2)].

Whereas advances in improving and simplifying the “floral dip” stage of the transformation have been developed, no significant advances in shortening or improving the selection process have been reported. Selection can be difficult; on germination, emerging cotyledons usually appear green, and transformed and non-transformed seedlings are frequently indistinguishable from each other. Over a period of 7–10 d, the non-transformants bleach and only the transformants remain green. During this lengthy period, fungal contamination may be a problem. Fungal contaminants may be present in seed stocks generated from floral dipping, because sucrose is used in the dipping medium and plants will have been, at least initially, kept in a warm damp environment providing ideal conditions for fungal growth. During seedling selection, fungal contaminants may deplete antibiotic or herbicide present in the selection medium, such that non-transformants are able to remain green. Crowding of seedlings on an agar plate may allow root growth above the medium and so result in a delay in bleaching of non-transformants due to decreased concentrations of selection agent. To address this problem, seedlings have been incubated in flasks of liquid growth medium on a rotary shaker instead of on agar-based medium [[3](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1636043/#B3)]. This ensures dispersal of the floating seedlings across the medium surface and ensures that all are exposed to the antibiotic or herbicide. Seedlings are then sorted to identify those that are green. However, the procedure does not always work well and seedlings can be of poor quality, appearing flaccid and waterlogged; these seedlings seldom survive transplantation to soil.

We have developed a method of seedling selection that results in rapid, easy identification of transformants; the protocol presented works well for screening for resistance to kanamycin, phosphinothricin and hygromycin B.

I’m pretty sure If you will compare pictures of both ( Cardamine and Arabidopsis) and then state the differences , everyone could easily be able to understand and know much more about it.

Urgent @Priti_Kanade Please tell us what are your ideas in culturing and maintaining and what exactly you would suggest a newcomer to address.

Cardamine is easy to culture  
Thanks to its small size and life span  
We get multiple generations in a year  
From a seed to next generation seed  
The time taken is 2 months!  
What you need to take care is to add enough water to Cardamine and follow up 😇

First  
Sow 100 seedlings in petriplate with moist tissue paper  
We expect sees to germinate in a week  
We’ll observe radical, plumule and first cotyledon  
Then we can transfer the seedlings into seedling tray

Water them daily  
Follow their growth pattern  
Take good pictures

Meanwhile make preparations for floral dip

Post 6 weeks  
We expect first floral bud to emerge with 7th leaf state

Follow it from bud with green sepals to the one with white closed petals covered with green sepals

We need

1. unopened floral bud of normal Cardamine

2. _A.tumefaciens_ strain with plasmid used for transformation with _GUS and / or Kanamycin resistance gene as reporter genes_ this will help us determine how many of our seeds have really tranformed as they will get selected in a selective medium like kanamycin, others won’t ( _here we have not introduced Gene of interest in plasmid, only marker)_

3. A proper growth media  
I’ll read more about the components required

4. Black plastic bag to maintain humidity

5. Antibiotic to be put in media to allow selection and for generation of transformed seeds
