How plants respond to heat stress

By | Climate change, News, Plant Science

Feeling the heat: Steroid hormones contribute to the heat stress resistance of plants. Plants, like other organisms, can be severely affected by heat stress. To increase their chances of survival, they activate the heat shock response, a molecular pathway also employed by human and animal cells for stress protection. Researchers have now discovered that plant steroid hormones can promote this response in plants.

Shoots and roots respond differently to climate change

By | Climate change, News

Most organisms follow a timetable – when to reproduce, when to migrate, so on so forth! The timing of such key periodic life events is known as phenology and is crucial for organism’s survival and their contributions to ecosystem functions. One of the most reported responses of organisms to contemporary climate change is shifts in their phenology. Ecologists have already shown that phenology of many plants are advancing due to climate change, for instance, many plants are flowering earlier during the growing season. But little was known how plant phenological changes aboveground matches with plant phenological changes belowground due to climate change.

Climate change: call to action

By | Blog, Climate change, Policy

The recent IPCC report has been called a wake-up call. It’s not. That was 30 years ago. Since then, we’ve been hitting the snooze button. We are starting to see the beginning of catastrophic climate change. This is already affecting our ability to feed everyone, the nutritional quality of plants and their interactions with animals (including us), human health and biodiversity. This is exacerbated by clearing of native forests and destruction of natural ecosystems for short term gain. The warming is not going to stop at 1.5 °C, or 2°C or even 5°C unless action is taken across the board. There is an urgent need to make it easier for individuals, industry, and agriculture to decarbonise the economy and preserve the environment.

Fast-forward breeding and rapid delivery systems for food security

By | Agriculture, Climate change, News

The current world population of 7.8 billion is predicted to reach 10 billion by 2057. Future access to affordable and healthy food will be challenging, with malnutrition already affecting one in three people worldwide. Two new papers recognized that global crop production systems need to expand their outputs sustainably to feed this rapidly growing human population.
