“…16 The time to heading in wheat is accelerated by green light in a fluence-rate-dependent manner, 17 and an action spectrum shows a peak at 540-550 nm. 18 This peak is consistent with that described as maximum for stomatal opening reversal, 13 green-induced dormancy maintenance in ryegrass 19 and green-driven inhibition of elongation in cress roots during gravitropic bending. 20 These findings represent some of the physiological alterations brought on by green light illumination, alone, or in concert with other wavelengths.…”

To a plant, the sun's light is not exclusively energy for photosynthesis, it also provides information about time and prevailing conditions. The plant's surroundings may dampen or filter solar energies, presenting plants with different spectral profiles of their light environment. Plants use this information to adjust form and physiology, tailoring gene expression to best match ambient conditions. Extensive literature exists on how blue, red and far-red light contribute to plant adaptive responses. A growing body of work identifies effects of green light (500-565 nm) that also shape plant biology. Green light responses are known to be either mediated through, or independent of, the cryptochrome blue light receptors. Responses to green light share a general tendency to oppose blue- or red-light-induced responses, including stem growth rate inhibition, anthocyanin accumulation and chloroplast gene expression. Recent evidence demonstrates a role for green light in sensing a shaded environment, independent from far-red shade responses.

“…The heading time of wheat does not seem to be affected by blue light (400-500 nm), but plants grown in high-fl uence-rate green-yellow light (500-600 nm) require fewer days to reach 50% heading ( Kasajima et al, 2007 ) Analysis of inductive wavebands showed that 540 nm imposed the strongest flowering stimulation effect ( Kasajima et al, 2008( Kasajima et al, , 2009 ).…”

Light passing through or refl ected from adjacent foliage provides a developing plant with information that is used to guide specifi c genetic and physiological processes. Changes in gene expression underlie adaptation to, or avoidance of, the light-compromised environment. These changes have been well described and are mostly attributed to a decrease in the red light to far-red light ratio and/or a reduction in blue light fl uence rate. In most cases, these changes rely on the integration of red/far-red/blue light signals, leading to changes in phytohormone levels. Studies over the last decade have described distinct responses to green light and/or a shift of the blue-green, or red-green ratio. Responses to green light are typically low-light responses, suggesting that they may contribute to the adaptation to growth under foliage or within close proximity to other plants. This review summarizes the growth responses in artifi cially manipulated light environments with an emphasis on the roles of green wavebands. The information may be extended to understanding the infl uence of green light in shade avoidance responses as well as other plant developmental and physiological processes.

Bread wheat is a major crop that has long been the focus of basic and breeding research. Assembly of its genome has been difficult because of its large size and allohexaploid nature (AABBDD genome). Following the first reported assembly of the genome of the experimental strain Chinese Spring (CS), the 10+ Wheat Genomes Project was launched to produce multiple assemblies of worldwide modern cultivars. The only Asian cultivar in the project is Norin 61, a representative Japanese cultivar adapted to grow across a broad latitudinal range, mostly characterized by a wet climate and a short growing season. Here, we characterize key aspects of its chromosome-scale genome assembly spanning 15 Gb with a raw scaffold N50 of 23 Mb. Analysis of the repetitive elements identified chromosomal regions unique to Norin 61 that encompass a tandem array of the pathogenesis-related-13 family. We report novel copy-number variations in the B homeolog of the florigen gene FT1/VRN3, pseudogenization of its D homeolog, and the association of its A homeologous alleles with the spring/winter growth habit. Further, the Norin 61 genome carries typical East Asian functional variants from CS ranging from a single nucleotide to multi-Mb scale. Examples of such variation are the Fhb1 locus, which confers Fusarium head-blight resistance, Ppd-D1a, which confers early flowering, Glu-D1f for Asian noodle quality, and Rht-D1b, which introduced semi-dwarfism during the green revolution. The adoption of Norin 61 as a reference assembly for functional and evolutionary studies will enable comprehensive characterization of the underexploited Asian bread wheat diversity.
