A new analysis of more than 20,000 trees on five continents shows that old-growth trees are more drought tolerant than younger trees in the forest canopy and may be better able to withstand future climate extremes.
A plant common to Japan, Causonis japonica, is the first to show a newly discovered trait. Its flowers can change color depending on the stage of its maturation cycle, and then change back to its original color. Although many flowers have been shown to change color depending on their maturation phase, Causonis japonica is the only known example of bidirectional color change.
Iron (Fe) is an indispensable micronutrient for plants since it is necessary for many important cellular processes. In order to survive Fe-deficient environments, plants have evolved sophisticated Fe deficiency responses for maintenance of Fe homeostasis. Recent studies have shown that Fe deficiency induces the resistance of plants to several pathogens. However, the molecular mechanism by which Fe deficiency induces the resistance to pathogens is unclear.
Rice (Oryza sativa L.) is one of the most important crops worldwide, providing much of the calorific needs for half of the global population. Economic development and rising living standards have led to the demand for rice gradually shifting from satisfying the need to “be full” to satisfying the need to “eat well,” and combining flavor with nutrition is essential for the latter. Much research has focused on improving the eating and cooking quality (ECQ) of rice to meet the demand for “tasty.” However, effort to improve comprehensive nutrition in rice remains fragmented.
Researchers have shown that plants can regulate the chemistry of their petal surface to create iridescent signals visible to bees.
What makes the perfect avocado? In a world-first, scientists have mapped the genome of the popular fruit, a resource that can drive future research and innovation opportunities for avocado growers.
In a new study scientists have found that smallholder farmers in Ethiopia grow more of the indigenous crop Ensete ventricosum in the direct aftermath of severe droughts as a means of bolstering food security.
Over 300 million people in Sub-Saharan Africa depend on maize for nearly 30% of their caloric intake, and the popularity of maize is expected to continue its upward trend. As the demand for maize increases, so does the need for sustainable and safe production, yet numerous biotic and abiotic stressors threaten this staple crop.
The protein BICAT3 is one of the most important manganese distributors in plants. If defective, this can have devastating effects on a plant’s growth; its leaves grow significantly smaller and it produces fewer seeds than usual. A team has recently uncovered a transport pathway for manganese in plants and the role that BICAT3 plays in this process. The results could lay the groundwork for improved crop growth.
Scientists have traced back plant defence mechanisms to a single receptor that evolved over millions of years to recognise today’s diseases and pests.
