“…The locus identifiers of the Aquilegia STY ‐like genes were obtained from the previous RNAseq data: Aqcoe6G257900, Aqcoe5G181200 and Aqcoe2G040300 (Yant et al ., ). To confirm their orthology, a 123‐locus alignment containing putative STY / SHI gene family homologs was constructed via BLAST searches in GenBank, Phytozome and the DFCI Plant Gene Index, including previously identified STY family members from A. thaliana , Populous trichocarpa , Oryza sativa , Lycopersicon esculentus , Nicotiana benthaniana , Medicago truncatula , Solanum tuberosum , Zea mays , Vitis vinifera , Selaginella moellendorfii and P. patens (Kuusk et al ., ; Eklund et al ., 2010b; Topp & Rasmussen, ). All amino acid sequences were aligned using C lustalw (Larkin et al ., ) as implemented in M ac V ector (Gary, NC, USA) and then adjusted by hand.…”

Homologs of the STYLISH gene family control nectary development in Aquilegia

Floral nectaries are an interesting example of a convergent trait in flowering plants, and are associated with the diversification of numerous angiosperm lineages, including the adaptive radiation of the New World Aquilegia species. However, we know very little as to what genes contribute to nectary development and evolution, particularly in noncore eudicot taxa. We analyzed expression patterns and used RNAi-based methods to investigate the functions of homologs from the STYLISH (STY) family in nectar spur development in Aquilegia coerulea. We found that AqSTY1 exhibits concentrated expression in the presumptive nectary of the growing spur tip, and triple gene silencing of the three STY-like genes revealed that they function in style and nectary development. Strong expression of STY homologs was also detected in the nectary-bearing petals of Delphinium and Epimedium. Our results suggest that the novel recruitment of STY homologs to control nectary development is likely to have occurred before the diversification of the Ranunculaceae and Berberidaceae. To date, the STY homologs of the Ranunculales are the only alternative loci for the control of nectary development in flowering plants, providing a critical data point in understanding the evolutionary origin and developmental basis of nectaries.

“…Owing to the fact that natural selection will act to remove dominant alleles that result in dwarf stature in the face of competition for light, healthy dwarf genotypes are expected to be rare, and difficult to obtain through traditional tree breeding [20]. Therefore, insertion of dominant transgenes may be an alternative method for obtaining dwarf phenotypes in many species [60]. Increasing or decreasing GA levels has been explored in several species, by over-expressing or silencing genes involved in GA biosynthesis pathway [60].…”

Breadfruit [Artocarpus altilis (Parkinson) Fosberg)] is a traditional staple crop grown for its starchy fruit throughout the tropics. It has long been recognized for its potential to alleviate hunger in the region. However, being a tree of 10 -30m, breadfruit is vulnerable to wind damage. Owing to the continuing trend of global climate change, the success of the species as a sustainable crop for delivering local food security is compromised by the likelihood of more intense tropical windstorms in the island nations. Tree height also forms a major constraint to disease management and fruit harvesting. These imperatives have driven an increasing interest in developing breadfruit varieties with short stature. While a great diversity of breadfruit cultivars with varying nutritional and agronomic characteristics exists, the genetic resource showing dwarfing traits is largely uncharacterised. Historically, there has been no intentional breeding for breadfruit cultivars. The long growth cycle, predominantly vegetative propagation and lack of genome information create challenge for crop improvement through traditional breeding. In this review, we highlight the current knowledge of plant dwarfism and its application in agricultural practices and genetic improvement for dwarf phenotype, and present options and tools for breadfruit dwarfing with special reference to natural genetic variability for dwarfing rootstocks, plant growth regulators, potential of mutagenesis and its combination with the currently Review Article

“…GAs play fundamental functions in plant growth and reducing level of active GAs causes the dwarf phenotype in plants [17]. Therefore, the attempts to alter GAs metabolism and/or signaling have been performed to control plant size [18, 19]. GA 20-oxidase (GA20ox), GA 3-oxidase (GA3ox), and GA 2-oxidase (GA2ox) catalyzing later reactions are key enzymes controlling GA biosynthesis [20].…”

Litchi (Litchi chinesis Sonn.) is the most economically significant member of Sapindaceae family, especially in sub-tropical regions. However, its tall tree body often brings many inconveniences to production management. In order to modify the tree size or growth for productivity optimization and simplifying management, it is urgent to reveal the dwarf mechanism of litchi for dwarfing rootstocks or cultivar breeding. However, to date, the mechanisms on litchi dwarfism is still poor known. In the present study, transcriptome profiling were performed on L. chinensis cv. ‘Feizixiao’ (FZX, vigorous cultivar) and ‘Ziniangxi’ (ZNX, dwarf cultivar). A total of 55,810 unigenes were obtained, and 9,190 unigenes were differentially expressed between vigorous and dwarf litchi samples. Gene functional enrichment analysis indicated that the differentially expressed unigenes (DEGs) were related to phytohormone metabolism and signal transduction, and energy metabolism pathways. In particular, GA2ox were only up-regulated in ZNX samples, indicating GA might play an important role in regulating huge difference between vigorous and dwarf litchi cultivars. In addition, the 35S::LcGA2ox transgenic tobacco plants were dwarf and had smaller leaves or branches than wild type plants. Our study provided a series of candidate genes to reveal the mechanism of litchi dwarf.
