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...

Examining the Causal Impact of Prenatal Home Visiting on Birth Outcomes: A Propensity Score Analysis
In Ohio, African American babies die at 2.5–3 times the rate of White babies. Preterm birth and low birth weight are the leading causes of infant mortality. Home visiting is an evidence-based strategy for serv...

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...

Space to Learn and Grow: Assessing the Capacity of a Regional Early Care and Education System
As communities across the United States work to meet the early care and education needs of young children, more research is needed to inform decision making at many levels. One key dimension of this is having ...

Genomic Imprinting in Arabidopsis thaliana and Zea mays
Genomic imprinting is the differential expression of paternal and maternal alleles. In plants, gene imprinting occurs in the endosperm and has not been found in the embryo or adult plants. Imprinting can ...

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, maturation and function of tomato fruit polygalacturonase
Ripening represents a major transition in tomato fruit development. This developmental transition is manifested by alterations in metabolism that contribute to final fruit colour, flavour and texture. It has b...

Diverse mechanisms for the regulation of ethylene-inducible gene expression
We have investigated the mechanism of action of the plant hormone ethylene by analyzing the expression of ethylene-inducible genes isolated from tomato (Lycopersicon esculentum). We have found that the expression...

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...

Organization of Soybean Seed Protein Genes and Their Flanking Regions
In this paper we review briefly the research which has been carried out in our lab on the organization of soybean seed protein genes. The genes which we have concentrated our efforts on encode the storage prot...
