First experimental evidence that WIPs in males of Drosophila melanogaster are targets of mate choice from females are presented, and that two different color traits—saturation and hue—experience directional and stabilizing sexual selection, respectively are presented.
Expression of SHOOT MERISTEMLESS, WUSCHEL, and ASYMMETRIC LEAVES1 Homologs in the Shoots of Podostemaceae: Implications for the Evolution of Novel Shoot Organogenesis[W]
The results suggest that the leaf of Podostemoideae is initiated as a SAM and differentiates into a single apical leaf/bract, resulting in the evolution of novel shoot-leaf mixed organs in Podostemaceae.
IscR Regulates RNase LS Activity by Repressing rnlA Transcription
It is concluded that IscR negatively regulates transcription of rnlA and represses RNase LS activity, causing the loss of antagonist activity against phage T4.
Origin and development of the cryptic shoot meristem in Zeylanidium lichenoides (Podostemaceae).
ZlSTM expression demonstrated that the meristematic identity is partly retained in the embryonic shoot apex of Z. lichenoides and how it is involved in plumular leaf development in the seedling is determined.
Gene expression analysis of aquatic angiosperms podostemaceae to gain insight into the evolution of their enigmatic morphology.
A gene expression analysis found that the SAM-less Podostemoideae leaf has mixed identity of SAM and leaf, and provided insight into the evolution of the shoot in Podostemaceae.

Estimation of distribution probability showed great contributions of geology and temperature to the distribution of these populations, suggesting that the species grow on volcanic rocks in relatively warm areas, and high-level genetic differentiations among populations of the two species may result from their limited dispersal.
Developmental anatomy of the reproductive shoot in Hydrobryum japonicum (Podostemaceae)
Bract development, like vegetative leaf development, is unique to this podostemad, while floral-organ development is conserved.

Podostemaceae are a eudicot family of plants that grow on rapid streams and waterfalls. Two genera and six species of this family are distributed in Japan, all of which are threatened with…

It is inferred that the conventional embryonic shoot meristem was lost in Podostemaceae via two steps, that is, the loss of a distinct L1 layer and the Loss of the OC, whereas the lost of the embryonic root meristems occurred once by misspecification of the hypophysis.
Expression pattern of CUC3 ortholog in Zeylanidium tailichenoides (Podostemaceae) infers organization of a unique distichous shoot in Podostemoideae
Examining gene expression patterns in plumular shoots of Zeylanidium tailichenoides using CUP-SHAPED COTYLEDON 3 (CUC3) and SHOOT MERISTEMLESS (STM) orthologs demonstrates that each Z. tailichenos shoot arises as an axillary bud in a manner similar to axillary meristem formation in model plants involving CUC3 and STM genes.
