Live session to discuss the experimental demo of Lab 8. We answered questions about the requirements for an in vitro culture experiment. We also said goodbye :) Thank you all for watching the videos.

In vitro culture experiment demonstrating how you can generate shoots, roots, and call from leaf and stem piths from tobacco. Principles of sterile technique are shown as well as the evaluation of…

Explore the concept of plant organogenesis and the steps to culture plants in vitro as a preparation to lab 8. This is our last intro video for the course PLS100BL, Winter 2021

Live session to present some of the students' video projects and to discuss the content of the final exam. An overview of the most important topics to consider for the final exam were provided.

Set up of 4 ethylene treatments (0 ppm, 0.1 ppm, 1 ppm, and 10 ppm) to observe responses of tomato explants and sunflower seedlings. We demonstrate the effect of ethylene in leaf epinasty and the…

Live session discussing the experiments on plant responses to ethylene and abiotic stress for Lab 7. Details on the report are provided.

Waterlogging effects on tomato plant growth and morphology. We observe tomato plants after their roots are submerged in water for 12, 9, 6, and 3 days. The formation of adventitious roots and the…

Intro video about ethylene and its functions in plants for Lab 7. Details about the biosynthesis and perception of ethylene in plants are provided.

Experimental design and demo of the role of GA and ABA on plant growth using hormone-deficient mutants. The photos and phenotypic data of the mutants are coded for the students to figure things out.…

Practical explanation by Dr. Mar Rubio about how to set the Li-COR instrument to gather gas exchange data in leaves of the ABA deficient mutant (sit) and WT tomato plants with and without ABA sprays.

Video showing how leaf color measurements were done using a colorimeter (Chroma Meter, Minolta). Leaves from a GA-deficient mutant (gib-1) and WT plants sprayed or not sprayed with GA were used for…

A quick recap about plant hormones and more details about the functions of gibberellins (GA) and abscisic acid (ABA). Mutants in the biosynthesis of GA and ABA are mentioned to prepare for Lab 6.

Live session to show the experimental setup for the plant growth analysis and fruit load experiments. The requirements for Lab 5 Report were explained in detail. During group office hours, we talked…

A cool time lapse video of tomato plants growing under light and shade conditions in the greenhouse for 55 days. Followed by a demo explaining how the measurements of plant growth were made for these…

Explanation on how the fruit load experiment was set up for Lab 5. The three treatments: all fruits, one fruit per truss, and no fruits are discussed in detail by Ryan Eadry.

Video introducing the basis of plant growth analysis and how carbon allocation may affect the overall growth of a plant. An explanation of plant growth curves (total crop) is provided. The…
