“…In other plants, dormancy and related cellular changes such as tissue water status, chilling and meristem growth are linked through the actions of the DAM (dormancy associated MADS box) and DREB (dehydration-responsive element binding proteins) genes [62][63][64][65], indicating that switchgrass orthologs of these genes will be reasonable targets for future study.…”

“…In several other plants, such as grasses with summer dormancy or tree buds with winter dormancy, spontaneous mutations or divergent selection can yield plants which lack dormancy [4,64,[80][81][82]. Depending on the environmental stress that is placed on these plants, responses can be neutral, positive or negative.…”

“…Depending on the environmental stress that is placed on these plants, responses can be neutral, positive or negative. However, the basal mechanisms affecting these changes appear to come from specific genes (DAM genes in peach; [64]) which are of importance to dormancy in other dicot species or from a suite of traits that primarily affect the onset leaf senescence in grasses experiencing summer dormancy [4,6,81]. These studies point to potential mechanisms that tie into the overall integration of timely aerial senescence to the onset of dormancy in the perenniating structures, and provide targets for study in the temperate C 4 perennial grasses.…”

Senescence, dormancy and tillering in perennial C4 grasses

a b s t r a c tPerennial, temperate, C 4 grasses, such as switchgrass and miscanthus have been tabbed as sources of herbaceous biomass for the production of green fuels and chemicals based on a number of positive agronomic traits. Although there is important literature on the management of these species for biomass production on marginal lands, numerous aspects of their biology are as yet unexplored at the molecular level. Perenniality, a key agronomic trait, is a function of plant dormancy and winter survival of the belowground parts of the plants. These include the crowns, rhizomes and meristems that will produce tillers. Maintaining meristem viability is critical for the continued survival of the plants. Plant tillers emerge from the dormant crown and rhizome meristems at the start of the growing period in the spring, progress through a phase of vegetative growth, followed by flowering and eventually undergo senescence. There is nutrient mobilization from the aerial portions of the plant to the crowns and rhizomes during tiller senescence. Signals arising from the shoots and from the environment can be expected to be integrated as the plants enter into dormancy. Plant senescence and dormancy have been well studied in several dicot species and offer a potential framework to understand these processes in temperate C 4 perennial grasses. The availability of latitudinally adapted populations for switchgrass presents an opportunity to dissect molecular mechanisms that can impact senescence, dormancy and winter survival. Given the large increase in genomic and other resources for switchgrass, it is anticipated that projected molecular studies with switchgrass will have a broader impact on related species.

“…Full-length cDNA cloning of the MADSbox gene and phylogenetic analysis revealed that the gene was similar to the StMADS11 clade MADS-box genes of Arabidopsis, such as SHORT VEGETATIVE PHASE (SVP) and AGAMOUS-LIKE24 (AGL24) (Yamane et al, 2008). Bielenberg et al (2008) independently identified six StMADS11 clade MADS-box genes as candidate genes associated with terminal bud formation in peach. Early studies had identified a mutant that failed to cease growth and to enter dormancy under dormancy-inducing conditions in peach; this is known as evergrowing (evg) (USDA PI442380) and was first identified in southern Mexico (Rodriguez et al, 1994).…”

Bud dormancy allows most deciduous fruit tree species to avoid injury in unsuitable environments, synchronize their annual growth, and adapt to a temperate zone climate. Because bud dormancy affects next season's fruit production and vegetative growth, it is considered one of the most important physiological factors that control fruit production. Recent global climate changes require us to better understand the genetic factors regulating bud dormancy, especially those that induce dormancy release and subsequent bud break. In this review, environmental factors that affect the seasonal dormancy depth of Japanese apricot (P. mume Siebold & Zucc.) and peach [P. persica (L.) Batsch] are first outlined. Next, recent progress of genetic, biochemical, and molecular biological studies of Prunus dormancy regulation is described. Recent advances in functional genomics have promoted the discovery of gene function and gene networks associated with bud dormancy regulation. A group of candidate genes for bud dormancy regulation, the DORMANCY-ASSOCIATED MADS-box (DAM) genes in Prunus, are focused. Recently reported expressional analysis suggests a significant role for DAMs in dormancy release and bud break of Japanese apricot and peach vegetative buds. Transformation studies of PmDAM6 have demonstrated that it has an inhibitory effect on the apical growth of poplar (Populus spp.). As bud dormancy is a quantitative polygenic trait, not only DAMs, but also other genes and gene networks appear to regulate bud dormancy. Ongoing and future studies will undoubtedly facilitate the unveiling of the molecular aspects of bud dormancy regulation in temperate fruit tree species of Prunus.

Plant architecture results from developmental processes occurring throughout the plant life span. In the current article, the processes responsible for the formation of aerial organs and their organization at the whole plant scale, i.e. primary and secondary growth, branching, and flowering are considered, whereas the below‐ground plant organization is not included. This article focuses on the advances made on the comprehension of the physiologic and genetic base of plant architecture initially elucidated in plant models, and which are progressively being deciphered in a large range of species. The current knowledge allows comparisons of the processes among groups and to examine their conservation versus their major differences. However, numerous questions remain especially when regularities in plant structure are observed at coarse scales of plant organization such as annual shoots, axes, or branching systems. Moreover, the overlap of numerous gene functions over several processes leads to pleiotropic effects that make the genetic effects complex to interpret. The evidence of such overlaps opens evo‐devo perspectives.
