A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Isoprene‐Emitting Transgenic Tobacco Shapes Root Microbiome and Enhances Growth of Co‐Cultivated Non‐Emitting Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT Isoprene is the most abundant biogenic volatile organic compound emitted by terrestrial vegetation. Here we report the impact of isoprene on root‐associated microbiomes. Using isoprene‐emitting (IE) transgenic tobacco and isogenic non‐emitting (NE) controls, we performed co‐cultivation experiments in natural soil and analysed plant phenotypes ...

Challenges for weed management in African rice systems in a changing climate [PDF]

, 2011
Global changes including increases in temperature, atmospheric greenhouse gases, soil degradation and competition for land and water resources, will have multiple impacts on rice production systems in Africa.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

C4 Photosynthesis: Differentiating Causation and Coincidence [PDF]

, 2008
SummaryDetermination of the historical causes of organismal adaptations is difficult, but a recent study has suggested that at least one of the transitions to C4 photosynthesis was directly facilitated by changes in atmospheric CO2 levels. But what about

Ozone Susceptibility of Tropical Tree Species

Plant, Cell &Environment, EarlyView.
ABSTRACT Tropical forests account for approximately 60% of global terrestrial photosynthesis, yet their function into the future may be compromised by rising ground‐level ozone (O3) pollution. Although O3 is known to impair plant productivity, the physiological mechanisms underlying interspecific variation in O3 susceptibility—especially among tropical

Molecular investigation of how drought stress affects chlorophyll metabolism and photosynthesis in leaves of C3 and C4 plant species: A transcriptome meta-analysis

Heliyon
Drought stress has a significant impact on photosynthesis in plants, leading to reduced photosynthesis rates and affecting plant growth and yield. Understanding the effects of drought stress on photosynthetic pathways, particularly in C3 and C4 plants ...

Effects of Atmospheric CO2 Levels on the Susceptibility of Maize to Diverse Pathogens

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 has significant implications for crop productivity and food security. Based on studies in C3 plants, elevated CO2 (eCO2) can shape plant‐pathogen interactions, although the outcomes are often variable. The question of how eCO2 influences immunity and disease development in C4 plants, such as the globally important cereal

CO2 Fertilisation of Growth in Wild C4 Grasses may be Amplified by Upregulated Photosynthesis

Plant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 is expected to have limited direct effects on C4 photosynthesis because the carbon‐concentrating mechanism maintains near‐saturating CO2 at Rubisco. Consequently, growth responses of C4 plants to elevated CO2 (eCO2) are generally attributed to indirect improvements in plant water relations.
