TL;DR: This study suggests that the molecular signature of a specific combination of stresses on the transcriptome might be as unique as the impact of individual stresses, and underlines the difficulty to extrapolate conclusions obtained from the study of individual stress responses to more complex settings.
Journal ArticleDOI
A member of the maize isopentenyl transferase gene family, Zea mays isopentenyl transferase 2 (ZmIPT2), encodes a cytokinin biosynthetic enzyme expressed during kernel development. Cytokinin biosynthesis in maize.

TL;DR: It is demonstrated that at 8–10 days after pollination the endosperm and especially the basal transfer cell layer is a major site of ZmIPT2 expression, and that this expression persists in the BETL and the developing embryo into later kernel development stages, suggesting a major role in CK biosynthesis for kernel development.

Compositions and methods of use of acc oxidase polynucleotides and polypeptides
TL;DR: In this article, the expression of endogenous ACC oxidase genes was reduced to improve an agronomic characteristic of a crop plant, which may be maize, and yield increase and drought tolerance were observed.
Patent
Compositions et procédés d'utilisation de polynucléotides et de polypeptides de l'acc oxydase
TL;DR: L'invention concerne des compositions transgeniques and des procedes qui permettent de reduire l'expression de genes d'ACC oxydase endogene afin d'ameliorer une caracteristique agronomique d'une plante cultivee.
