Karyotype and Genome Size Determination of Jarilla Chocola, an Additional Sister Clade of Carica Papaya
POJ 14(01):50-56 (2021) ISSN:1836-3644 doi: 10.21475/POJ.14.01.21.p2944 Karyotype and genome size determination of Jarilla chocola, an additional sister clade of Carica papaya Dessireé Patricia Zerpa-Catanho1, Tahira Jatt2, Ray Ming1* 1Department of Plant Biology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA 2Department of Botany, Shah Abdul Latif University, Khaipur, Sindh, 66020, Pakistan *Corresponding author: [email protected] Abstract Jarilla chocola is an herbaceous plant species that belongs to the Jarilla genus and the Caricaceae family. No information on chromosome number or genome size has been reported for J. chocola that confirms the occurrence of dysploidy events and explore the existence of heteromorphic sex chromosomes. Therefore, the total number of chromosomes of this species was determined by karyotyping and counting the number of chromosomes observed, and the genome size of female and male plants was estimated separately by flow cytometry. Results showed that J. chocola has eight pairs of chromosomes (2n = 2x = 16), and its chromosomes are classified as metacentric for five pairs, submetacentric for two pairs and telocentric for one pair. The nuclear DNA content (1C- value) in picograms and diploid genome size was estimated separately from female and male plants using two species as the standards, Phaseolus vulgaris (1C = 0.60 pg) and Carica papaya (1C = 0.325 pg), to look for the possible existence of heteromorphic sex chromosomes. C. papaya proved to be a better standard for the determination of J. chocola DNA content and diploid genome size. No significant difference on the DNA content was observed between female (1C = 1.02 ± 0.003 pg) and male (1C = 1.02 ± 0.008 pg) plants.

Terms such as lignotuber, xylopodium and sobole, all referring to belowground bud-bearing structures, are used inconsistently in the literature. Key words: bud bank, fire-prone ecosystems, Because soil efficiently insulates meristems from the heat of fire, concealing buds below ground lignotuber, resprouting, rhizome, xylopodium. provides fitness benefits in fire-prone ecosystems. Thus, in these ecosystems, there is a remarkable diversity of bud-bearing structures. There are at least six locations where belowground buds are stored: roots, root crown, rhizomes, woody burls, fleshy

([email protected]). §Corresponding author: [email protected]. Abstract The wild populations of papaya (Carica papaya L.) integrate a biological resource for the genetic improvement of the species. The prediction of the geographical distribution of wild and cultivated populations is a useful tool to determine collection sites for their use and conservation. With the objective of estimating the potential distribution of papaya in Mexico, a database with geo- reference information of wild and cultivated papaya individuals was elaborated, then the maximum entropy algorithm (MaxEnt) was applied with 22 bioclimatic variables as predictors. The total area of potential distribution of the wild specimens was 114 546.5 km2, the high potential areas were located in the Gulf of Mexico (south of Veracruz, Tabasco, Campeche) and on the coast of Chiapas. The cultivated papaya presented a high potential distribution in three zones: south of Veracruz, coast of Chiapas and north of Guerrero, forming 185 396.9 km2.

Evidence for Emergence of Sex-Determining Gene(S) in a Centromeric Region in Vasconcellea Parviflora

Abstract Sex chromosomes have been studied in many plant and animal species. However, few species are suitable as models to study the evolutionary histories of sex chromosomes. We previously demonstrated that papaya (Carica papaya) (2n=2x=18), a fruit tree in the family Caricaceae, contains recently emerged but cytologically heteromorphic X/Y chromosomes. We have been intrigued by the possible presence and evolution of sex chromosomes in other dioecious Caricaceae species. We selected a set of 22 bacterial artificial chromosome (BAC) clones that are distributed along the papaya X/Y chromosomes. These BACs were mapped to the meiotic pachytene chromosomes of Vasconcellea parviflora (2n=2x=18), a species that diverged from papaya ~27 million years ago. We demonstrate that V. parviflora contains a pair of heteromorphic X/Y chromosomes that are homologous to the papaya X/Y chromosomes. The comparative mapping results revealed that the male-specific regions of the Y chromosomes (MSYs) probably initiated near the centromere of the Y chromosomes in both species.

WOOD and BARK ANATOMY of CARICACEAE; CORRELATIONS with SYSTEMATICS and HABIT by Sherwin Carlquist
IAWA Journal, Vol. 19 (2), 1998: 191-206 WOOD AND BARK ANATOMY OF CARICACEAE; CORRELATIONS WITH SYSTEMATICS AND HABIT by Sherwin Carlquist Santa Barbara Botanic Garden, 1212 Mission Canyon Road, Santa Barbara, CA 93105, U.S.A. SUMMARY Wood and bark anatomy are described for four species of three genera of Caricaceae; both root and stem material were available for Jacaratia hassleriana. Wood of all species lacks libriform fibers in secondary xylem, and has axial parenchyma instead. Cylicomorpha parviflora has paratracheal parenchyma cells with thin lignified walls; otherwise, all cell walls of secondary xylem in Caricaceae except those of vessels have only primary walls. Vessels have alternate laterally elongate (pseudo scalariform) pits on vessel-vessel interfaces, but wide, minimally bor dered scalariform pits on vessel-parenchyma contacts. Laticifers occur commonly in tangential plates in fascicular secondary xylem, and rarely in xylem rays. Proliferation of axial parenchyma by zones of tangential divisions is newly reported for the family. Bark is diverse in the spe cies, although some features (e.g., druses) are common to all. Wood of Caricaceae is compared to that of two species of Moringaceae, recently designated the sister family of Caricaceae. Although the wood and bark of Moringa oleifera, a treelike species, differ from those of Caricaceae, wood and bark of the stem succulent M. hildebrandtii, the habit of which resembles those in Caricaceae, simulate wood and bark of Caricaceae closely. Counterparts to laticifers in Moringaceae are uncertain, how ever. Phloem fibers of Caricaceae form an expansible peripheral cylin der of mechanical tissue that correlates with the stem succulence of most species of Caricaceae.

Accepted 5 December, 2011 Ethnobotanical investigations were conducted in four Lewoh-Lebang villages (Attuleh, Leleng, Mbindia and Nyitebong) in Lebialem Division, Southwest Region of Cameroon to identify the different plants used in traditional pharmacopoeia for the treatment of human diseases and also to find out other uses of plants in this community. Ethnobotanical information was collected randomly using semi- structured questionnaires and open-ended discussion with male, female and traditional healers, using different age groups. A total of 108 respondents were interviewed and (56%) were male with age ≥55 years. Thirty (30) medicinal plants belonging to 21 families were identified and documented. Guarea thompsonii, Schefflera hierniana and Cyclomorpha solmsii are endemic/vulnerable species. 21 diseases were cured using 30 species with rheumatism being the most frequent ailment and the bark was the most frequently used plant part. 13 species were used as fuel wood, five for fencing, eleven as timber and fifteen for cultural activities.

Box 302-7050, Costa Rica *Corresponding author, e-mail: [email protected] ABSTRACT Papaya (Carica papaya Linn.) is a tropical plant whose draft genome has been sequenced. Papaya produces large fruits rich in vitamins A and C and is an important cash crop in developing countries. Nonetheless, little is known about how the female gametophyte develops, how it is fertilized and how it develops into a mature seed containing an embryo and an endosperm. The Papaya female gametophyte displays a Polygonum-type architecture consisting of two synergid cells, an egg cell, a central cell, and three antipodal cells. Reports are available of the presumed existence of varieties in which cross fertilization is bypassed and autonomous development of embryos occurs (e.g., apomixis). In this study, we analyzed the development of female gametophytes in a commercial Hawaiian parental line and in the presumed apomictic Costa Rican line L1.
