Plants reproduce sexually to ensure genetic variability and thus, to continuously evolve in a constantly changing environment. In angiosperms, flowers are the sexual organs and most angiosperms are hermaphroditic, this means they have bisexual flowers with both male and female organs (Figure 1). Stamens are the male part of the flower, they are filaments ended […]
In recent years, when I enter into a bakery my decision of which bread to buy is getting more and more complicated because of the high variety of bread available. Bread is “in appearance” a simple product just made out of flour, yeast and water mixed together and baked. Of course, the complexity of bread […]
Plants are sessile organisms, which means they can´t move around. Of course, they have some types of movements like turning towards the sun but the place where the seed germinates the plant will stay during their entire life cycle. Obviously, this fact has important consequences on how plants respond upon variations of their surrounding environment […]
Most famous RNAs are coding or messenger RNAs (mRNAs) which are the ones that ribosomes read to synthesize proteins. However, many other RNAs are transcribed from DNA and are known as non-coding RNAs. Among those, ribosomic RNAs (rRNAs) which are part of the ribosomes and transfer RNAs (tRNAs) which deliver the amino acids to the […]
Everybody has heard about that. They say that plants are able to hear. Who has not ever heard from someone or read somewhere that talking to your plants makes them grow better and to be more splendid than if you treat them like a vegetable? You can believe it or not, but believer or skeptic […]
Every day, each person on the planet consumes 2868 Kcal, 19% of those calories come from the world’s most important crop, rice, closely followed by wheat (F.A.O). In some Asian countries such as Bangladesh, Indonesia or Philippines rice represents up to 70% of the daily caloric intake (Figure 1). Many research efforts have been done […]
The cover of this post probably shows the world’s most famous carnivorous plant (Figure 1). It´s name is Audrey II and it appeared in the music film “Little shop of horrors”, directed by Franz Oz in 1986 adapting the film “The Little Shop of Horrors” directed by Roger Corman in 1960. Audrey II is a […]
Nitrogen (N) is an essential nutrient for plant growth and most plants require 20-50 g of N taken up by their roots to produce 1 kg of dry biomass. Although N is one of the most abundant elements on earth, agricultural soils are deficient in N and thus, to sustain crops productivity soils require their […]
Many organisms, such as fungi and plants without seeds, produce spores as a dispersal mechanism. Spores are usually microscopic propagules, many of them are able to resist harsh environmental conditions and successfully germinate after a long period of time. We know that their size is so small (just a bunch of micrometers) that they can […]
Some plants have the capacity to develop tubers. Tubers are storage organs that serve as a survival strategy to better cope with adverse environmental conditions such as dry periods and cold. Tubers are sometimes also a means of asexual reproduction. In fact, tubers can persist in the soil during unfavorable conditions and generate a new […]
