Stomata are microscopic structures on the leaf epidermis that facilitate gas exchange between the plant and the environment. Thanks to these specialized cell types, plants are an essential component of the global carbon and water cycles. Plus, stomata not only interlink plants and climate but also influence the global water cycle.
Genetic engineering of chickpea to understand the mystery behind biochemical regulation in flower and seed coat colour of desi and kabuli genotypes
Flower and seed coat colour are important agronomic traits in chickpea that influence consumer preference. Based on their cultivation globally, this legume crop is categorized as “desi” or “kabuli”. Seeds of desi-type chickpeas are generally dark brown and angular with a rough seed coat, while the kabuli type produces light-brown coloured and rounded seeds with smooth seed coats. Recently, a group of scientists in India successfully developed a new genetically engineered selection marker-free stable chickpea line.
If not, Winter: How a super-charged “Speed Vernalization” protocol accelerates flowering in winter cereals
As days grow colder and shorter, and many of us find ourselves entrenched in winter, you wouldn’t be mistaken for feeling a noticeable reduction in activity around you. However, in certain crops such as winter wheat and barley, this cold season holds the key to flowering in the spring. This well-studied process, called vernalization, requires the plant to sense appropriate conditions – i.e., low temperature and short day-length – usually early in development to “overwinter” through several inhospitable months.
How we love chocolate! The big downside of this love is that more chocolate consumption directly implies more cocoa plantations, which has led to significant loss of forests especially in West Africa. In the coming decades is expected both an increase in demand and a decrease of suitable areas for growing cocoa due to climate change.
In multicellular organisms, distinct cell types are produced and maintained through the coordination of several progenitor lineages. How is this information stored in the transcriptome? Do these cells’ behaviors reflect their lineage history or their current biological surroundings?
Phenotypic plasticity in plants occurs at all biological scales in every organism. Phenotypic plasticity is defined as the physical and/or metabolic responses of organisms to their environment. Some plastic responses may be strategies that enhance fitness in specific environments. In contrast, other forms of plasticity may be symptoms of stress or pathology, all of which may develop at different time scales. A recent review highlights the characterization, costs, cues, and future perspectives of phenotypic plasticity.
Pruning is the art and science of cutting parts of a plant to increase production and ease harvest and spraying activities. In cocoa cultivation, pruning is recommended to farmers, although its effect on cocoa tree growth and cocoa bean production is not well understood.
Two years ago, in 2020, the entire world was engulfed in the COVID19 pandemic, which is caused by the severe acute respiratory syndrome coronavirus SARSCoV2. As everyone knows by now, the most common symptoms of this disease are fever, dry cough, fatigue, and headache, and can turn into a progressive and severe pneumonia. However, evidence suggests that COVID-19 patients may also develop a variety of neurological complications. Thousands of people died each day because there was no known treatment. The search for treatments and vaccines for this novel coronavirus disease was on.
Respiration in plants is a process that consumes sugars (e.g., glucose) and oxygen, produces carbon dioxide (CO2) and water, and releases energy to maintain the primary metabolic and physiological functions during growth. It determines the net carbon gain for plants and the carbon efflux for whole ecosystems.
