TLDR
The transition from the juvenile to the adult phase of shoot development in plants is accompanied by changes in vegetative morphology and an increase in reproductive potential, and the regulatory mechanism is described, which is mediated by sequentially operating miRNAs.About:

Regulation of OsSPL14 by OsmiR156 defines ideal plant architecture in rice
Yongqing Jiao,Yonghong Wang,Dawei Xue,Dawei Xue,Jing Wang,Meixian Yan,Guifu Liu,Guojun Dong,Dali Zeng,Zefu Lu,Xudong Zhu,Qian Qian,Jiayang Li +12 more
TL;DR: It is demonstrated that a point mutation in OsSPL14 perturbs OsmiR156-directed regulation of OsSPl14, generating an 'ideal' rice plant with a reduced tiller number, increased lodging resistance and enhanced grain yield.

Control of grain size, shape and quality by OsSPL16 in rice
Shaokui Wang,Kun Wu,Qingbo Yuan,Xueying Liu,Zhengbin Liu,Xiaoyan Lin,Ruizhen Zeng,Haitao Zhu,Guojun Dong,Qian Qian,Guiquan Zhang,Xiangdong Fu +11 more
TL;DR: It is shown that a quantitative trait locus GW8 is synonymous with OsSPL16, which encodes a protein that is a positive regulator of cell proliferation that promotes cell division and grain filling, with positive consequences for grain width and yield in rice.

Regulation of flowering time: all roads lead to Rome
Anusha Srikanth,Markus Schmid +1 more
TL;DR: An endogenous pathway that adds plant age to the control of flowering time has been described and the molecular mechanisms of these pathways have been studied extensively in Arabidopsisthaliana and several other flowering plants.

The C. elegans heterochronic gene lin-4 encodes small RNAs with antisense complementarity to lin-14
TL;DR: Two small lin-4 transcripts of approximately 22 and 61 nt were identified in C. elegans and found to contain sequences complementary to a repeated sequence element in the 3' untranslated region (UTR) of lin-14 mRNA, suggesting that lin- 4 regulates lin- 14 translation via an antisense RNA-RNA interaction.

The 21-nucleotide let-7 RNA regulates developmental timing in Caenorhabditis elegans
Brenda J. Reinhart,Frank J. Slack,Frank J. Slack,Michael Basson,Amy E. Pasquinelli,Bettinger Jc,Ann E. Rougvie,H R Horvitz,Gary Ruvkun +8 more
TL;DR: It is shown that let-7 is a heterochronic switch gene that encodes a temporally regulated 21-nucleotide RNA that is complementary to elements in the 3′ untranslated regions of the heteroch chronic genes lin-14, lin-28, Lin-41, lin -42 and daf-12, indicating that expression of these genes may be directly controlled by let- 7.

TL;DR: In this article, the authors propose a clock model of Heterochrony, which is a mechanism for separating the three stages of the development of an organism: birth, growth, and death.

TL;DR: This work predicts regulatory targets for 14 Arabidopsis microRNAs (miRNAs) by identifying mRNAs with near complementarity and identifies members of transcription factor gene families involved in developmental patterning or cell differentiation.
