Charla de difusión Escuela Agrícola Superior de Molina

El día 7 de marzo de 2017, Paz Zúñiga, Ingeniera en Biotecnología Vegetal y Asistente de Investigación, realizó la charla de difusión titulada "Hormonas vegetales y la maduración de los frutos" enmarcada en el proyecto Fondecyt Nº 1140663, a estudiantes de tercero y cuarto año de enseñanza media de la Escuela Agrícola Superior de Molina, Región del Maule. Desde ¿por qué los plátanos maduran fuera de la planta? hasta ¿cómo las hormonas regulan la expresión de ciertos genes? la finalidad de la charla consistió en acercar a los jóvenes al rol de las hormonas vegetales en los distintos procesos fisiológicos de las plantas y su uso dentro de la agricultura, con énfasis en el rol de la hormona jasmonato en la maduración de la frutilla (Fragaria x ananassa). Por su parte los alumnos se mostraron interesados, sobre todo en la aplicabilidad en campo y posibilidad de generar productos biotecnológicos usando hormonas.

Oxylipins Levels and Expression of Jasmonate Responsive Genes During Development and Ripening of Strawberry

The regulatory mechanisms of fruit ripening in non-climacteric fruits are complex and many hormones could be involved in this regulation. Jasmonates (JAs) have been found to play a role in the anthocyanin accumulation in several plant tissues including fruits.

Methyl Jasmonate and Chitosan Elicit Differential Expression of Pr- and Pgip-Related Genes in Response to Botrytis Cinerea Infection During Postharvest Storage of Chilean Strawberry Fruit

The chilean strawberry (Fragaria chiloensis) is appreciated as a very particular fruit because its characteristic aroma, flavor and color. However, this fruit has a short postharvest life due to the high susceptibility to infection by fungal pathogens including Botrytis cinerea.

Toward Understanding the Role of Jasmonates During Development and Ripening of Strawberry Fruit

Jasmonates (JAs) are phytohormones involved in stress responses, reproductive development and production of secondary metabolites, although its role in development and ripening of fleshy fruit is not well known.

COURSERA: Understanding Plants - Part I: Fundamentals of Plant Biology by Daniel Chamovitz, Manna Center for Plant Biosciences, Tel Aviv University, Israel

This course intends to present an intriguing and scientifically valid look at how plants themselves experience the world-from the colors they see to the sensations they feel. Highlighting the latest research in genetics and more, we will delve into the inner lives of plants and draw parallels with the human senses to reveal that we have much more in common with sunflowers and oak trees than we may realize. This class has three main goals: 1. To introduce you to basic plant biology by exploring plant senses (sight, smell, hearing, touch, taste, balance). 2. To introduce you to biological research and the scientific method. 3. To get the student to question life in general and what defines us as humans. Once you have taken this course, if you are interested in a more in-depth study of plants, check out the follow-up course, Fundamentals of Plant Biology.

COURSERA: Understanding Plants - Part II: Fundamentals of Plant Biology by Daniel Chamovitz, Manna Center for Plant Biosciences, Tel Aviv University, Israel

This class is aimed at people interested in understanding the basic science of plant biology. In this four lecture series, we will first learn about the structure-function of plants and of plant cells. Then we will try to understand how plants grow and develop, making such complex structures as flowers. Once we know how plants grow and develop, we will then delve into understanding photosynthesis - how plants take carbon dioxide from the air and water from soil, and turn this into oxygen for us to breathe and sugars for us to eat. In the last lecture we will learn about the fascinating, important and controversial science behind genetic engineering in agriculture.

Roots: The Hidden Half of Plant Adaptive Responses to Water Stress. Lecture by Dr. Malcolm Bennett, Nottingham University, UK

Roots play a crucial role in plant adaptation to water stress, yet have remained the ‘hidden half’ of plant biology due to researchers inability to non-invasively visualize roots in their natural soil environment. He had developed an interdisciplinary research approach to visualize roots directly in soil using X-ray based imaging techniques and software. This innovative approach has enabled his interdisciplinary team to characterise new and existing root adaptive mechanisms to water availability such as hydropatterning and hydrotropism.

Roots and the Hidden Half of Plant Biology. Lecture by Dr. José R. Dinneny, Carnegie Institution for Science, USA.

We see plants everywhere in our daily lives, but half of the plant, the root system, is hidden from our eyes. Dr. Dinneny discusses why studying roots is critical for our understanding of how plants respond to changes in the environment and why this knowledge may lead to the next green revolution.

What a Plant Knows with Dr. Daniel Chamovitz, Tel Aviv University, Israel

To understand life in the universe, we first must understand life on Earth - both animal and plant. Plant life impacts everything from the terrain under our feet to the air we breathe. Scientist and author Daniel Chamovitz unveils the surprising world of plants that see, feel, smell, and even remember.

Daniel Chamovitz studied at both Columbia University and the Hebrew University of Jerusalem, where he received his Ph.D. in Genetics. From 1993 to 1996 he carried out postdoctoral research at Yale University before accepting a faculty position at Tel Aviv University where he recently served as Chair of the Department of Plant Sciences.

Are Plants Conscious?

We already know that plants have all our senses (they can see, hear, touch, smell and see) without the organs usually associated with them and they have some more specific exclusive senses. We also know that they have very important and intense social lifes. But, are plants intelligent? Can they solve problems, communicate, and navigate their surroundings? 

In this talk, Stefano Mancuso presents a new paradigm in our understanding of the vegetal world. He argues that plants process information, sleep, remember, and signal to one another-showing that, far from passive machines, plants are intelligent and aware.

Stefano Mancuso is one of the most important figures in the field of plants neurobiology in the world. He is a lecturer in the University of Florence, director of the International Laboratory of Plant Neurobiology (LINV) in Florence, Italy, and a founder of the International Society for Plant Signaling and Behavior.

Plants-in-Motion

Plant Time-lapse movies

Created for nonprofit educational use by Roger P. Hangarte, Indiana University, USA

Although our lives depend on plants for virtually everything that keeps us alive (oxygen, food, fibers, lumber, fuel, etc), their lives remain a secret to most of us. The reason is simple - plants live on a different time-scale from ours. Although not usually obvious in the relatively hyperactive activities of humans, plants are in constant motion as they develop, search for light and nutrients, avoid predators, exploit neighbors, and reproduce.
