“…Furthermore, expression pattern of microRNAs involved in rice grain filling was investigated, which give new insight of how microRNAs regulate grain filling Peng, Sun, et al, 2013;Peng et al, 2014, Peng et al, 2011. Additionally, ETHYLENE RESPONSE2 (ETR2) is responsible for starch overaccumulation in stems and low grain weight (Panda, Badoghar, Sekhar, Shaw, & Mohapatra, 2016;Sekhar et al, 2015;Wuriyanghan et al, 2009). ERS1, ERS2, and ETR3 promote starch accumulation in inferior spikelets enhancing the grain filling (Sekhar et al, 2015;Wuriyanghan et al, 2009).…”

“…Meanwhile, OsCCS52A, which is an activator of the anaphase-promoting complex that initiates cyclin degradation, also mediates the exit from the mitotic cell cycle (Su'udi et al, 2012). The application of 1methylcyclopropene increased the frequency of nuclei ≥6C by promoting the production of CDKAs and CYCD2:2, while inhibiting the production of CYCB2:2 (Panda et al, 2016). In contrast to the emerging understanding of endocycle initiation, reiteration of the endocycle is less well understood in rice endosperm.…”

“…Endoreduplication in rice endosperm cells is regulated by phytohormones such as ethylene and cytokinin. The application of 1methylcyclopropene (an ethylene action inhibitor) and 6benzylaminopurine (a cytokinin) increases the ploidy of endosperm cells in the dense-panicle rice cultivar 'OR-1918' (Panda et al, 2016(Panda et al, , 2018. However, to the best of my knowledge, endoreduplication progression has not been compared among rice cultivars.…”

“…Effect of ethylene on filling of compact-panicle and lax-panicle in rice has been studied. The differential grain filling of the superior and inferior spikelets probably resulted from the higher content of ethylene in compact-panicle rice cultivar ( Yang et al, 2006b ; Panda et al, 2015 , 2016 ). The basal spikelets produce more ethylene at anthesis, and the expression of ethylene receptors and ethylene signaling transducers retained longer at post-anthesis compared to apical spikelets ( Sekhar et al, 2015 ).…”

“…Inhibitors including 1-MCP, AVG (aminoethoxyvinylglycine), and STS of ethylene biosynthesis or signaling have been useful in investigating the function of ethylene in rice grain filling. 1-MCP and AVG treatment increased cell number and size, and starch synthesizing enzyme gene expression, and ultimately improved grain filling ( Mohapatra and Mohapatra, 2006 ; Panda et al, 2016 ). Furthermore, 1-MCP treatment enhanced expression of cell cycle regulators such as cyclin dependent kinase ( CDK ), cyclin ( CYC ) and cyclin dependent kinase inhibitor ( CKI ) and ultimately increased grain filling ( Panda et al, 2016 ).…”
