Functional Phenomics: Studying Root Physiology Using Affordable Open Source Tools Recorded December 17, 2019   About This Webinar Functional phenomics is an emerging discipline that utilizes phenotyping, physiology, multivariate statistics, and simulation modeling to generate and test new…

With global temperatures rising, tolerance to heat is becoming increasingly important as a breeding target for crop plants, but it is a highly complex response that includes processes including plant cooling capacity, growth recovery, and maintenance of photosynthesis. Using Arabidopsis, Gao et al. developed…

Root research got a boost from Arabidopsis grown on Petri plants, but what do you do if you study something bigger, or want to see how roots grow in soil? Zheng et al. developed a new set of tools they call CREAMD-COFE [Core Root Excavation using Compressed-air (to extract the roots from soil), and Core…

Root system architecture (RSA) describes the spatial arrangement of root components within the soil. RSA is useful to understand the exploration of the plant to get nutrients and water through the soil space. In a new review, Correa et al. discuss RSA plasticity in response to soil compaction, which…

Bulliform cells lie in rows along the upper (adaxial) surface of the maize leaf, and through changes in volume contribute to leaf-rolling, which is a response to water deficit. Several mutants have been identified that affect bulliform cell formation and function, but as yet their occurance in natural…

The world demands food, plant scientists and breeders have the challenge of feeding a growing population. In a recent review Hickey et al. summarize the state-of-the-art technologies used for crop improvement. In use since 2003, ‘speed breeding’ is a set of improved methods for fast-tracking plant…

Root system architecture (RSA) profoundly affects plant nutritent uptake and response to drought, and is also famously extremely developmental plastic, which makes it difficult to identify genes that control root growth traits. Here, Jiang et al. analyzed 3D growth patterns over time of three maize lines…

Uptake of water by plants depends on root conductivity, which in turn is determined by hydraulic properties of individual cells and cell anatomy. Quantification of radial root anatomy is a time-consuming process, limiting our understanding of root anatomical features contributing to water uptake. Heymans…
