Harnessing the hidden genetic diversity for improving multiple abiotic stress tolerance in rice
Plant Science Research Weekly, Research0 Comments
/
Ali et al. describe a rice breeding strategy to improve abiotic stress tolerance as well as to accelerate the speed to achieving homozygosity. The researchers named this particular technique as “Green Super Rice” (GSR) breeding technology. They use a backcross (BC) breeding approach to fix breeding…
Bypassing negative epistasis on yield in tomato imposed by a domestication gene
Plant Science Research Weekly, ResearchTomatoes normally grow as multiple flowers along a single branch. Soyk et al. explored a large collection of wild and domesticated accessions to identify those with branched inflorescences, which should be able to produce more fruit per plant. They identified a few related branchy mutants which they…

Review: Systems-wide understanding of photosynthetic acclimation in algae and higher plants ($)
Plant Science Research Weekly, ResearchDeriving energy from light is a bit like keeping your hands warm by juggling burning coals; doable but dangerous. Photosynthetic organisms constantly adjust their photosynthetic machinery to optimize energy production but avoid damage from excess light. Moejes et al. describe a large-scale project,…
Review: Enhancing genetic gain in the era of molecular breeding ($)
Plant Science Research Weekly, ResearchYield is determined by the crop’s genetic potential and the realization of that potential as affected by agronomic practices and environmental factors. Xu et al. address how yields can be improved through enhancing genetic gain, which they define as “the amount of increase in performance that is…
Review: Communication in the phytobiome ($)
Plant Science Research Weekly, ResearchAn old ad stated, “Without chemicals, life itself would be impossible,” but it’s only more recently that we’ve begun to understand the importance of semiochemicals – chemicals produced for communication. Leach et al. pull together insights from chemical ecologists, soil scientists, plant pathologists…
Special Issue: Legumes – From Food Security to Climate Change
Plant Science Research Weekly, ResearchThe April issue of J. Exp. Bot is a special issue on Legumes. The Editorial introduction, by Considine et al. (10.1093/jxb/erx099) observes that grain legumes “will form a cornerstone of future food and nutritional security and a global web of biodiversity.” Issue articles span topics including genomics…
Student-driven plant breeding symposium addresses global challenges in the 21st century
GPC BlogThis week we spoke to Francisco Gomez and Ammani Kyanam, graduate students in the Soil and Crop Science Department at Texas A&M University, USA. They were part of the organizing committee for the recent Texas A&M Plant Breeding Symposium, a successful meeting run entirely by students at the University.

Hybridizing transgenic Bt cotton with non-Bt cotton counters resistance in pink bollworm
Plant Science Research Weekly, ResearchBiotic interactions are complex; any effort by the prey/host to defend against the predator/pathogen provides selective pressure towards overcoming those defenses. As new herbivore control methods are developed they quickly lose effectiveness as the pests evolve resistance; this is true whether the control…
