A primitive Y chromosome in papaya marks incipient sex chromosome evolution
Many diverse systems for sex determination have evolved in plants and animals. One involves physically distinct (heteromorphic) sex chromosomes (X and Y, or Z and W) that are homozygous in one sex… Expand
The pineapple genome and the evolution of CAM photosynthesis
Pineapple (Ananas comosus (L.) Merr.) is the most economically valuable crop possessing crassulacean acid metabolism (CAM), a photosynthetic carbon assimilation pathway with high water-use… Expand

The phylogenetic relationships among twelve wild and cultivated species of Carica (Caricaceae) were analyzed using restriction fragment length variation in a 3.2-kb PCR amplified intergenic spacer… Expand
Genetic diversity of Carica papaya as revealed by AFLP markers.
Genetic relationships among Carica papaya cultivars, breeding lines, unimproved germplasm, and related species were established using amplified fragment length polymorphism (AFLP) markers.… Expand

Since 1992, Papaya ringspot virus (PRSV) destroyed nearly all of the papaya hectarage in the Puna district of Hawaii, where 95% of Hawaii's papayas are grown. Two field trials to evaluate transgenic… Expand
Use of a Tissue Blotting Immunoassay to Examine the Distribution of Pineapple Closterovirus in Hawaii.
Specific monoclonal antibodies made to a pineapple closterovirus (PCV) were used in a tissue blotting immunoassay (TBIA) for the detection of PCV in pineapple. More than 2,000 samples were tested in… Expand
Association of Enterobacter cloacae with Rhizome Rot of Edible Ginger in Hawaii.
Edible ginger is a popular spice crop that is grown in Hawaii primarily for the fresh market, and as such, rhizome quality is of paramount importance. In our studies, a Gram-negative, facultative… Expand
Diversity and Mealybug Transmissibility of Ampeloviruses in Pineapple.
Mealybug wilt of pineapple (MWP) is one of the most destructive diseases of pineapple (Ananas comosus) worldwide. At least one Ampelovirus species, Pineapple mealybug wilt associated virus-2… Expand
Origin and domestication of papaya Yh chromosome.
Sex in papaya is controlled by a pair of nascent sex chromosomes. Females are XX, and two slightly different Y chromosomes distinguish males (XY) and hermaphrodites (XY(h)). The… Expand
