Open AccessH2A.X promotes endosperm-specific DNA methylation in Arabidopsis thaliana
H2A.X is an H2A variant histone in eukaryotes, unique for its ability to respond to DNA damage, initiating the DNA repair pathway. H2A.X replacement within the histone octamer is mediated by the FAcilitates Ch...

Open AccessEffects of APETALA2 on embryo, endosperm, and seed coat development determine seed size in Arabidopsis
Arabidopsis APETALA2 (AP2) controls seed mass maternally, with ap2 mutants producing larger seeds than wild type. Here, we show that AP2 influences development of the three major seed compartments: embryo, endosp...

SEUSS and LEUNIG regulate cell proliferation, vascular development and organ polarity in Arabidopsis petals
Unlike in animals where cell migrations and programmed cell death play key roles in organ shape determination, in plants organ shape is largely a result of coordinated cellular growth (cell divisions and cell ...

fist: an Arabidopsis mutant with altered cell division planes and radial pattern disruption during embryogenesis
A T-DNA-tagged, embryo-defective Arabidopsis thaliana mutant, fist, was identified and shown to exhibit defects in nuclear positioning and cell division orientation beginning at the four-cell stage of the embryo...

Production of the Sweet Protein Monellin in Transgetic Plants
Monellin is a protein that elicits a flavor approximately 100,000 times sweeter than sugar on a molar basis. The protein exists naturally as a heterodimer, with its sweet flavor lost upon denaturation. A singl...

Regulation of Gene Expression by Ethylene
In plants, many processes are regulated by a small number of hormones: auxin, abscisic acid, cytokinin, gibberellin, and ethylene (for review, see Wareing and Phillips, 1981). Plant hormones, like animal hormo...
