“…Despite this long and productive exchange between plant and animal breeding and evolution, evo-devo has rarely been explicitly integrated into these research programs. Yet, yields of many of the world major food crops have plateaued (Tester and Langridge 2010;de Bossoreille de Ribou et al 2013;Grassini et al 2013), suggesting an end to the "green revolution." By mid-century the world's population will reach nine billion (Conway and Wilson 2012).…”

“…The challenges associated with providing a secure food supply for the global population are numerous, though few are likely as pressing as increasing agricultural productivity while decreasing environmental degradation. Yet, yields of many of the world major food crops have plateaued (Tester and Langridge 2010;de Bossoreille de Ribou et al 2013;Grassini et al 2013), suggesting an end to the "green revolution." Moreover, human induced changes to climate will require the increased use of land currently unsuitable for agriculture.…”

Evolutionary developmental biology (evo-devo) has undergone dramatic transformations since its emergence as a distinct discipline. This paper aims to highlight the scope, power, and future promise of evo-devo to transform and unify diverse aspects of biology. We articulate key questions at the core of eleven biological disciplines-from Evolution, Development, Paleontology, and Neurobiology to Cellular and Molecular Biology, Quantitative Genetics, Human Diseases, Ecology, Agriculture and Science Education, and lastly, Evolutionary Developmental Biology itself-and discuss why evo-devo is uniquely situated to substantially improve our ability to find meaningful answers to these fundamental questions. We posit that the tools, concepts, and ways of thinking developed by evo-devo have profound potential to advance, integrate, and unify biological sciences as well as inform policy decisions and illuminate science education. We look to the next generation of evolutionary developmental biologists to help shape this process as we confront the scientific challenges of the 21st century.

“…Research has therefore focused on regulators of fundamental developmental processes in plants, such as flowering, allowing the establishment of new breeding programs (e.g., Jung and Müller, 2009). Members of the FT-like gene family are key regulators of flowering in diverse plant species, and are therefore common targets for crop improvement (e.g., de Bossoreille de Ribou et al, 2013;Wickland and Hanzawa, 2015).…”

“…Although it is apparent that the effects of stress on crop productivity are most severe at developmental stages such as male gametophyte development [ 5 ], the molecular factors and regulatory networks underlying environmental stress-induced male gametophytic alterations are still largely unknown in plants in general [ 44 ]. This study elucidates some of the potential functions of a previously uncharacterised gene in the model species Arabidopsis thaliana .…”

“…In model plants like Arabidopsis thaliana , tolerance is often measured as “survival”, whilst in crop species like cereals, maintenance of “yield” and “productivity” is for economic reasons more important than survival [ 4 ]. The shifting of breeding goals towards “low input, high output” agriculture increases the need for genetic dissection of quantitative traits controlling adaptive responses and performance of crops under environmentally constrained conditions, especially during developmental stages such as male gametophyte development, the transition to flowering phase or grain filling [ 5 ].…”

Overexpressing the Multiple-Stress Responsive Gene At1g74450 Reduces Plant Height and Male Fertility in Arabidopsis thaliana

et al. 2015

A subset of genes in Arabidopsis thaliana is known to be up-regulated in response to a wide range of different environmental stress factors. However, not all of these genes are characterized as yet with respect to their functions. In this study, we used transgenic knockout, overexpression and reporter gene approaches to try to elucidate the biological roles of five unknown multiple-stress responsive genes in Arabidopsis. The selected genes have the following locus identifiers: At1g18740, At1g74450, At4g27652, At4g29780 and At5g12010. Firstly, T-DNA insertion knockout lines were identified for each locus and screened for altered phenotypes. None of the lines were found to be visually different from wildtype Col-0. Secondly, 35S-driven overexpression lines were generated for each open reading frame. Analysis of these transgenic lines showed altered phenotypes for lines overexpressing the At1g74450 ORF. Plants overexpressing the multiple-stress responsive gene At1g74450 are stunted in height and have reduced male fertility. Alexander staining of anthers from flowers at developmental stage 12–13 showed either an absence or a reduction in viable pollen compared to wildtype Col-0 and At1g74450 knockout lines. Interestingly, the effects of stress on crop productivity are most severe at developmental stages such as male gametophyte development. However, the molecular factors and regulatory networks underlying environmental stress-induced male gametophytic alterations are still largely unknown. Our results indicate that the At1g74450 gene provides a potential link between multiple environmental stresses, plant height and pollen development. In addition, ruthenium red staining analysis showed that At1g74450 may affect the composition of the inner seed coat mucilage layer. Finally, C-terminal GFP fusion proteins for At1g74450 were shown to localise to the cytosol.
