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.
For the first time, farmers in the Philippines have cultivated Golden Rice on a larger scale and harvested almost 70 tonnes of grains this October.
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.
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.
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.
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.
Researchers have found that rhizobial bacteria are hijacking a key protein in legumes involved in molecular transport to control how the symbiotic cellular structures that allow the plants to take up nitrogen form between the two organisms.
Plants do not possess nerves and muscles that enable rapid movement in animals. However, Mimosa pudica, commonly called touch-me-not, shame or sensitive plant, moves its leaves by bending the motor organ “pulvinus” immediately in response to touch and wounds. Since the era of Charles Darwin, this spectacular leaf movement has been studied. However, the long-distance signaling molecules that trigger the rapid leaf movements and the physiological roles of this movement remain unexplored.
Scientists in Colombia show that well managed pasture can store more soil carbon while reducing nitrous oxide (N2O) emissions to offset the climate impact of livestock.
The evolution of tree roots may have triggered a series of mass extinctions that rocked the Earth’s oceans during the Devonian Period over 300 million years ago, according to a study.
