Morphological characterization and relationships of wild tomatoes (Solanum L. Section Lycopersicon [Mill.] Wettst. Subsection Lycopersicon)

open access: yes, 2005
Wild tomatoes (Solanum Lycopersicon (Mill.) Wettst.) are native to western South America. Different classifications have been based on morphological or biological species concepts. Molecular data from mitochondrial DNA restriction sites, nuclear and chloroplast DNA restriction length fragment polymorphisms, and most recently gene sequences of the ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

A Century of Understanding and Harnessing Heterosis

open access: yesPlant 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 ...

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Rhizosphere Engineering by Root Exudates: High‐Yielding Alfalfa Recruits Functional PGPR to Sustain Soil Nutrient Availability Under Long‐Term Cultivation

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Soil nutrient transformation capacity is a critical determinant of sustainable productivity in perennial cropping systems; however, the extent to which high‐yielding crops actively regulate rhizosphere microbial assembly to maintain nutrient availability remains poorly understood.
