Abstract: A method and apparatus for determining a reflectance, of at least a portion of a target object, in at least one selected wavelength range of electromagnetic (EM) radiation are disclosed. The method comprises, for each selected wavelength range, providing a digital image including at least one target object and a plurality of reference objects, each reference object having respective non-identical predetermined reflectance characteristics, with a digital camera arrangement that provides output image data that comprises digital numbers that are responsive to radiation, in only a selected wavelength range, incident at a sensing plane of the digital camera arrangement. A relationship between a first set of the digital numbers is determined and a first set of the respective predetermined reflectance characteristics of the reference objects. Responsive to the relationship, a further set of digital numbers is transformed to allocate a value of reflectance for each of the digital numbers in the further set.

Abstract: The invention relates to methods of increasing water use efficiency (WUE) in plants by modulating the stomatal blue light response. The invention further relates to plants having increased WUE, identifying plants with increased WUE and to related methods of increasing drought tolerance and producing food or feed products under water-limited or drought conditions.

Abstract: Aspects of the present disclosure relate to genetically altered plants with enhanced biomass including genetic alterations that stimulate RubP regeneration and electron transport. In particular, the present disclosure relates to genetically altered plants with enhanced biomass through overexpression of CB proteins (e.g., FBPase/SBPase or SBPase), and overexpression of photosynthetic electron transport proteins (e.g., cytochrome c6 and Rieske FeS).
