Historical gains in soybean (Glycine max Merr.) seed yield are driven by linear increases in light interception, energy conversion, and partitioning efficiencies Koester et al.
Linear increases in light interception, energy conversion, and partitioning efficiencies have driven past yield gains in soybean. In modern cultivars, canopy light interception and harvest index are reaching theoretical maximum values
Transcriptional responses indicate maintenance of photosynthetic proteins as key to the exceptional chilling tolerance of C4 photosynthesis in Miscanthus×giganteus
C4 photosynthesis is impaired typically by chilling, but not in Miscanthus×giganteus. Global transcript profiling reveals that expression of many key photosynthetic genes is maintained or up-regulated during chilling in Miscanthus×giganteus in contrast to maize, suggesting a basis for chilling-tolerant C4 photosynthesis
Deconstructing Kranz anatomy to understand C4 evolution Lundgren, Osborne, Christin
In this review, we use a quantitative dataset for grasses (Poaceae) and examples from other groups to isolate the changes in anatomical characters that generate these functional properties, including changes in the size, number and distribution of different cell types
Linking chlorophyll-a fluorescence to photosynthesis for remote sensing applications: mechanisms and challenges Porcar-Castell et al.
We revisit the theory connecting chlorophyll-a fluorescence to photosynthesis in the spatiotemporal context of remote sensing. Physical, physiological and methodological factors are discussed and a roadmap to future research presented
From proto-Kranz to C4 Kranz: building the bridge to C4 photosynthesis Sage, Khoshravesh, Sage
Here we present a structure-function analysis addressing how Kranz anatomy may have evolved by describing the conceptual models of C4 evolution. The importance of photorespiration is also discussed and a case that Kranz anatomy originated as a structure to enable the trapping and recycling of photorespired CO2 is presented
Increasing tomato fruit quality by enhancing fruit chloroplast function. A double-edged sword Cocaliadis et al.
Chloroplast contribution to fruit development and ripening is reviewed in the light of recent results that fruit may have recruited transcription factors enhancing chloroplast development to improve fruit organoleptic properties
Leaf senescence and nitrogen use efficiency in oilseed rape (Brassica napus L.) Avice and Etienne
Bundle sheath leakiness in C4 photosynthesis: a careful balancing act between CO2 concentration and assimilation Kromdijk et al.
This paper reviews improvements in methodology to estimate leakiness, synthesize reports on bundle sheath leakiness, discuss different interpretations, and highlight areas where future research is necessary
Light to liquid fuel: theoretical and realized energy conversion efficiency of Crassulacean Acid Metabolism (CAM) in arid conditions Davis, LeBauer and Long
Theoretical energy yields from CAM plants in dry climates are greater than theoretical energy yields from C4 and C3 plants cultivated in wet climates.
Life and death under salt stress: same players, different timing? Ismail, Nick and Takeda
The molecular nature of the signals evoked after onset of salt stress seems to be general, and should not be suited to confer specificity per se. The focus of the current review is therefore shifted to the temporal patterns of signals conveyed by molecules such as Ca2+, H+, ROS, ABA, and JA.
Root anatomical phenes associated with water acquisition from drying soil: targets for crop improvement Lynch, Chimungu and Brown
This review discusses anatomical traits that can improve water acquisition from drying soils, followed by anatomical traits that influence radial and axial water transport. We then consider traits that improve root penetration of hard, drying soil.
The fruit, the whole fruit and everything about the fruit Kourmpetli and Drea
Review on the genetic regulation of fruit development from initiation through harvesting with a focus on two very different fruit types; the opium poppy capsule and the grain of cereals
Carbon isotope discrimination as a tool to explore C4 photosynthesis von Caemmerer et al.
The theory of C4 photosynthetic carbon isotope discrimination is reviewed highlighting gaps in our understanding and how it can be used to probe the coordination and diversity of C4 photosynthesis
Transposable elements, a treasure trove to decipher epigenetic variation: insights from Arabidopsis and crop epigenomes Mirouze and Vitte
We discuss the similarities and differences existing between Arabidopsis and crops epigenomes. We explore the relationship between TEs and epigenomes, and provide insights onto the challenges towards using epigenetic diversity in plant breeding programs.
Connections between circadian clocks and carbon metabolism reveal species-specific effects on growth control Muller, von Korff and Davis
This review discusses the reciprocal regulatory interaction between the circadian clock and carbon metabolism and its impact on stress signaling and water use.

Epigenetic control of plant senescence and linked processes Ay, Janack, Humbeck
Evidence is increasing that leaf senescence is regulated via epigenetic mechanisms. This epigenetic control level interconnects senescence pathways and other regulatory networks of stress responses and development
The expanded tomato fruit volatile landscape Rambla et al.
A tomato fruit volatile review is presented which addresses updated biosynthesis pathways, control of emission by conjugation and hydrolisis, and discussion about the difficulties and opportunities for breeding better-tasting tomatoes
Autophagy, plant senescence and nutrient recycling Avila-Ospina et al.
In plants, as in other eukaryotes, autophagy is associated with cell longevity and nutrient recycling. Relationships between leaf senescence, cell death, nitrogen management, and autophagy are discussed
Genomic analyses of the CAM plant pineapple Zhang, Liu, Ming
Arguments in the evo-devo debate: say it with flowers! Della Pina, Souer and Koes
Plants, display an astonishing morphological diversity, which evolved relatively quickly. The review addresses the genetic alterations underlying the evolution of this diversity and how that altered development.
Naive methods, rather than yield complexity, constrain the improvement of crop adaptation to drought; predicting how traits scale to crop level and a dual perspective on water and nitrogen are advocated
Chronologies of the shifts between photosynthetic modes are provided for a range of facultative CAM species. Combined with new sequencing technologies, facultative systems will contribute towards understanding the principles of CAM.
The Human Mind as a common denominator in plant domestication Abbo, Lev-Yadun and Gopher
Recent experiments demonstrated that deep sowing was not a general unconscious selection pressure underlying the increased seed size of domesticated legumes. We suggest the permanent need for human decision-making as a general factor
Symplastic intercellular transport from a developmental perspective Y Benitez-Alfonso
Communication between neighbouring cells is essential for the co-ordinated development of multicellular organisms. New knowledge on plasmodesmata composition, their regulation, and their importance during embryonic and post-embryonic organ development is reviewed
Somatic embryogenesis: life and death processes during apical–basal patterning Smertenko and Bozhkov
Early embryos consist of the apical domain which gives rise to the mature embryo and the basal domain which is gradually eliminated by PCD. Molecular pathways regulating development of each domain are reviewed.
The efforts to harness transpiration efficiency (TE); that is, the genetic component of water-use efficiency are reviewed and discussed.
The stay-green trait Thomas and Ougham
The biologically and agriculturally important stay-green trait results from altered expression of senescence genes. This paper reviews the physiological basis of different kinds of stay-green in crop and model species.
C1A cysteine protease-cystatin intercation in leaf senescence Diaz-Mendoza et al.
This overview article is focussed on barley, as the unique species where the whole gene family members of C1A cysteine proteases and cystatins have been analysed
Alternative splicing plays an important role in regulating gene functions and enhancing the diversity of the proteome in plants. Most of the genes are interrupted by introns in Arabidopsis. More than one half of the intron-split genes involved in multiple biological processes including the circadian clock are alternatively spliced
Overview of the long-term improvement of maize yield for the US corn-belt that has been achieved by the Pioneer breeding effort, emphasizing the role of drought and genetic improvements in drought tolerance, and discuss key results that have enabled the delivery of the AQUAmax® suite of maize hybrids with improved yield performance under drought conditions
miRNAs in the crosstalk between phytohormone signalling pathways Curaba, Singh, Bhalla
We review some of the recent knowledge on the molecular connections of miRNAs involved in multiple hormonal responses and discuss their potential implication as mediators of hormonal crosstalk in specific developmental processes.
This paper examines the significance of the relation between QTL expression and crop management using the example of fruit load management, a common practice in the cultivation of many different annual and perennial species producing fruits.
