Botanists show for the first time that reduced phosphorus investment in lipids in plants improves phosphorus use efficiency in rice without reducing photosynthesis.

OsDCL1 activation compromises resistance against rice blast fungus
Rice blast, caused by the pathogen Magnaporthe oryzae, is the most important fungal disease of cultivated rice (Oryza sativa). Salvador-Guirao et al. investigate the contribution of DCL1, the core component for microRNA...
Pelota genes regulate root development and defense responses in rice
Seeds of the grass species rice (Oryza sativa) serve as the most widely consumed staple food especially in Asia. One of its major threats is Xanthomonas oryzae pv. oryzae (Xoo), the causal agent of rice bacterial...

Ammonium uptake promotion by silicon in rice
Turgor-driven plant cell growth depends on cell wall structure and mechanics. Strengthening of cell walls on the basis of an association and interaction with silicon (Si) could lead to improved nutrient uptake and...
The role of gibberellin in iron homeostasis in rice
The plant hormone gibberellin (GA) participates in many physiological processes. However, little is known about the role of GA in responses to nutrient deficiency in general and iron deficiency in particular. Wang et al...
Rice resistance responses to the root-knot nematode Meloidogyne graminicola
Meloidogyne graminicola is responsible for production losses in rice (Oryza sativa) in Asia and Latin America. Petitot et al. assess the cytological and molecular mechanisms underlying nematode resistance identified in...
Rice seedling tolerance of salinity and anoxic conditions
Rice (Oryza sativa) can germinate and emerge from anoxic, flooded soils. Salinity, however, compromises seedling establishment. Kurniasih et al. assess the energy requirements for ion regulation in rice coleoptiles...
Boron toxicity tolerance mediated by H2 during rice seed germination
Boron (B) is essential for plant growth, but hazardous when present in excess. Hydrogen gas (H2) possesses antioxidant properties. Wang et al. investigate B-induced biological responses during rice (Oryza sativa) seed...
C4 Wheat? Lend an ear to hear more
One of the Grand Challenges – and, arguably, the Holy Grail – of plant research at present is an attempt to improve the photosynthetic efficiency of plants. Somewhat surprisingly, the fundamental photosynthetic pathway...

High-temperature drying increases longevity of rice seed
This study investigates the conditions routinely used by genebanks and finds that standard practice may not be optimal for subsequent seed longevity.
Aluminum alleviates manganese toxicity by reducing its availability
Aluminum alleviates manganese toxicity by altering the properties of root cell membranes and cell walls in rice.
Strigolactones and adventitious root formation in rice
Strigolactones (SLs) and their derivatives are plant hormones that have recently been identified as regulating root development. Sun et al. study adventious roots (ARs) in SL-deficient (d10) and SL-insensitive (d3)...
Phylogeny of OVATE family proteins in land plants
The OVATE gene encodes a nuclear-localized regulatory protein belonging to a distinct family of plant-specific proteins known as the OVATE family proteins (OFPs). Liu et al. identify 13 sequenced plant genomes in public...
How rice germinates under water
Rice has the rare ability to germinate and elongate a coleoptile under oxygen-deficient conditions. Here's why.
