This system has demonstrated that optimizing nutrient flow can improve root growth and nitrogen uptake, leading to enhanced crop yields, say IIT Guwahati researchers.

Their innovative use of microfluidic technology to analyze root behavior holds the potential to significantly enhance crop management.

Findings

The team’s findings have been published in the prestigious journal, Labon a Chip, published by The Royal Society of Chemistry, in a paper co-authored by Mr. Kaushal Agarwal, Dr. Sumit Kumar Mehta, and Prof. Pranab Kumar Mondal.

The work has also been accepted to be featured as a cover art of the upcoming issue of the journal, say IIT Guwahati researchers.

Primary Root

The primary root of a germinating seed serves as the plant’s anchor, crucial for absorbing water and nutrients, say IIT Guwahati researchers.

This root must navigate various soil conditions during early growth, a critical phase for plant survival. Factors such as nutrient supply, pH levels, soil composition, aeration, and temperature significantly influence root development, say IIT Guwahati researchers.

However, studying root dynamics has been challenging due to the limitations of traditional experimental setups, which often require large containers and complex handling.

Their research work has been supported by the Science and Engineering Research Board (SERB/ANRF), Govt. of India, say IIT Guwahati researchers.

Existing microdevices primarily focus on phenomena like root-bacteria interactions, hormonal signaling, and pollen tube growth, with limited exploration into real-time plant root dynamics.

Specifically, the impact of mechanical stimuli from nutrient flow on root growth and thigmomorphogenesis (the response of plants to mechanical stress) has not been extensively studied.

To address these challenges, IIT Guwahati researchers investigated the high-yielding mustard variety, Pusa Jai Kisan, known for its effective root diameter in the micrometer range.

Their goal was to understand how different nutrient flow conditions influence root growth and nitrogen uptake during the critical post-germination stages, say IIT Guwahati researchers.

About The Work

Dr. Pranab K. Mondal spoke about work of IIT Guwahati researchers. Our study provides new insights into plant root dynamics through the use of microfluidic devices.

We validated our setup’s design and findings by simulating nutrient flow, measuring nitrogen uptake, and analyzing the effects of nutrient uptake and fluid pressure on root cells, he said.

This research enhances our understanding of how mechanical stimuli and nutrient uptake interact, with practical implications for agriculture, he said.

Beyond this point, excessive flow-induced stress reduced root length. Notably, roots exposed to flow conditions consistently performed better than those in no-flow conditions due to superior nitrogen uptake.

This research highlights that carefully managed nutrient flow induces significant morphological changes in the root, promoting plant growth.

Looking ahead, the team plans to explore the molecular mechanisms underlying flow-induced changes in root growth, say IIT Guwahati researchers.

Understanding these cellular and molecular processes could lead to the development of more resilient hydroponic systems and support soil-less crop production.

The schedule to submit applications for JEE Advanced 2025 has been announced along with that of AAT 2025 registration,

Application process for AAT starts after result declaration of JEE Advanced. This year too, the trend is no different.

Who will conduct AAT 2025?

AAT 2025 will be conducted by IIT Kanpur and is expected to see a participation in impressive numbers. The same institution is conducting JEE Advanced 2025.

Details about the exam are available on the official website mentioned above. Students who pass AAT 2025 will be able to study BArch in IIT Roorkee, IIT Kharagpur and IIT (BHU) Varnasi.

Who can take up AAT 2025 registration?

Students who have passed JEE Advanced 2025 with required qualifying marks can take up AAT 2025 registration. Applying for JEE Advanced requires a pass in JEE Mains.

Candidates who have passed plus two with maths, physics and chemistry as subjects will be able to take up JEE Mains registration. The process to take up JEE Advanced AAT 2025 registration is online.

1. The URL has to be typed into the browser and the webpage has to be allowed to download.

2. Once the website is available, students should click the link for JEE Advanced AAT 2025 registration and enter JEE Advanced 2025 registration number, their date of birth, mobile number and email address.

3. Post providing the above details, applicants will be asked if they are interested in AAT. Students have to answer ‘Yes’ to take up JEE Advanced AAT 2025 registration.

4. Candidates have to provide the required information and choose the centers where they wish to write the exam and submit the form.

5. They will receive message indicating successful completion of JEE Advanced AAT 2025 registration.

The message has to be downloaded and a printout of it has to be taken and preserved for use in future. This could be of use during the admission process.

Website for JEE Advanced 2025/AAT 2025 Registration is Here

Exam pattern

Candidates who have completed JEE Advanced AAT 2025 registration must also know the exam pattern if they are to score good marks.

Those who have taken up AAT 2025 registration can take up the exam which will be held in offline mode, as a pen and paper mode test.

Candidates will have three hours time to answer all the questions. The medium of the test is English.

The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

Syllabus for AAT 2025

The next thing to do after completing AAT 2025 registration is focus on preparing for the test.

The subjects to be studied while preparing for AAT 2025 are mentioned below. Candidates can also refer the official website for more information on syllabus when the registration for the exam begins:

Geometrical Drawing

Exercises in geometrical drawing containing lines, angles, triangles, quadrilaterals, polygons, circles, etc. Study of plan (top view), elevation (front or side views) of simple solid objects like prisms, cones, cylinders, cubes, splayed surface holders, etc.

Freehand Drawing

This would comprise of simple drawing depicting the total object in its right form and proportion, surface texture, relative location and details of its component parts in appropriate scale.

Common domestic or day-to-day life usable objects like furniture, equipment, etc., from memory.

Three dimension perception

Understanding and appreciation of three-dimensional forms with building elements, colour, volume and orientation. Visualization through structuring objects in memory.

Architectural Awareness

General interest and awareness of famous architectural creations – both national and international, places and personalities (architects, designers, etc.) in the related domain.

Imagination and Aesthetic Sensitivity

Composition exercise with given elements. Context mapping.

Creativity check through innovative uncommon test with familiar objects. Sense of colour grouping or application.

The medium of the test is English. The sections in the question paper are – Imagination and aesthetic sensitivity, three dimensional perception, Geometrical drawing, Freehand drawing and Architectural Awareness.

The admit cards obtained for JEE Advanced 2025 can also be used to gain entry into the test centers for AAT 2024.
