Abstract:

Different chemical, physical, and biological treatments were applied to emasculated flower buds of cotton hybrids (Gossypium hirsutum, 2n = 4x = 52) of various genotypes with the purpose of inducing haploid parthenogenesis. Of the treatments applied, the most effective chemical treatment was 0.2% colchicine in 0.2% dimethyl sulfoxide (1.22% parthenogenetic seed set), the most effective physical treatment was high temperature (2.66% parthenogenetic seed set), and the most effective biological treatment was pollination with Hibiscus cannabinus pollen (2.33% parthenogenetic seed set).

Abstract:

Apomixis is a naturally occurring mode of asexual reproduction in flowering plants that results in seed formation without the involvement of meiosis or fertilization of the egg. Seeds formed on an apomictic plant contain offspring genetically identical to the maternal plant. Apomixis has significant potential for preserving hybrid vigor from one generation to the next in highly productive crop plant genotypes. Apomictic Pennisetum/Cenchrus species, members of the Poaceae (grass) family, reproduce by apospory. Apospory is characterized by apomeiosis, the formation of unreduced embryo sacs deriv

Abstract:

The term “Geographical parthenogenesis” describes the phenomenon that asexual organisms usually occupy larger and more northern distribution areas than their sexual relatives, and tend to colonize previously glaciated areas. Several case studies on alpine and arctic plants confirm the geographical pattern, but the causal factors behind the phenomenon are still unclear. Research of the last decade in several plant families has shed light on the question and evaluated some of the classical evolutionary theories. Results confirmed, in general, that the advantages of uniparental reproduction enabl

Female flowers of cultivars Hartley and Pedro and two native Iranian selections (Z63 and Z67) were pollinated using pollen of selections Z53 and Z30 that had been irradiated with gamma rays at five doses (50, 150, 300, 600, and 900 Gy). Gamma-irradiated pollen induced fruit set and development of some parthenogenetic embryos. The immature embryos were excised 30 and 45 days after pollination, cultured in vitro, and then stratified for 30

Abstract:

Abstract Asexual seed production (agamospermy) via gametophytic apomixis in flowering plants typically involves the formation of an unreduced megagametophyte (via apospory or diplospory) and the parthenogenetic development of the unreduced egg cell into an embryo. Agamospermy is almost exclusively restricted to polyploids. In this study, the genetic basis of agamospermy was investigated in a segregating population of 130 F1's from a cross between triploid (2n = 27) agamospermous Erigeron annuus and sexual diploid (2n = 18) E. strigosus.

Abstract:

Reproduction of gall wasps is partially by sexual reproduction and partially by parthenogenesis, where the male is completely unnecessary. As in many species, however, there is an alternation of generations with one to two sexual generations and one parthenogenetic generation annually. This process differentiates the various generations in their appearance and in the way they induce the galls. The larvae of many species develop gallant characteristics; and there are also many species that are tenants or parasites of other gall wasps, such as those of the genus Synergus.

Abstract Parthenogenesis was induced in vitro in unpollinated ovaries of onion (Allium cepa L.). Sucrose concentration and stage of megaspore development affected parthenogenesis, while high- or low-temperature shocks had no stimulatory effect. Maximum embryo induction was on B5 medium supplemented with 2 mg 2,4-D/liter + 2 mg BA/liter and 10% sucrose. More than 250 plants were regenerated, of which 70% were determined cytologically to be haploid.

Abstract:

Background: Engineering apomixis in sexually reproducing plants has been long desired because of the potential to fix hybrid vigor. Validating the functionality of genes originated from apomictic species that contribute to apomixis upon transfer to sexually reproducing species is an important step. The PsASGR-BABYBOOM-like (PsASGR-BBML) gene from Pennisetum squamulatum confers parthenogenesis in this apomict, and its functionality was demonstrated in several sexually reproducing monocots but not in any dicots. Methods: We introduced the PsASGR-BBML gene regulated by egg cell-specific promoters

Abstract:

Gametophytic apomixis implies different changes of the reproductive cycle of sexual plants. Each of these "elements of apomixis" occurs in sexual plants, which may even display functional diploid parthenogenesis. Thus, apomixis, like vegetative reproduction, is part of the reproductive behaviour of sexual plants, becoming important when sexual reproduction is impaired. The elements of apomixis are probably to a large extent under polygenic control.

Abstract:

Apomixis, asexual or clonal seed production in plants, can decrease the cost of producing hybrid seed and enable currently open pollinated crops to be converted to more vigorous and higher yielding hybrids that can reproduce themselves through their own seed. Sexual reproduction may be triggered by a programmed stress signaling event that occurs in both the meiocyte, just prior to meiosis, and later in the egg just prior to embryo sac maturation. The prevention of stress signaling and the activation of a pro-growth signal prior to meiosis triggered apomeiosis, the first half of apomixis. The s

Abstract:

Host-Associated Differentiation (HAD) is the formation of genetically divergent hostassociated lineages maintained by ecological isolation. HAD is potentially an important route to ecological speciation in parasites including many insects. While HAD case studies are accumulating, there is a dearth of negative results in the literature making it difficult to know how common the phenomenon really is or whether there are specific traits of parasites which promote HAD. To address these two problems, studies are needed which both publish negative results (i.e., parasites not showing HAD) and test f

Abstract:

“Roman Assimilation of Greek Myths and Botany” traces the absorption of Greek botanical thought by the Romans. Although Roman thinkers—Cato the Elder, Varro, Virgil and Columella—wrote about agriculture, theoretical botany was largely abandoned, while the one—sex model of plants remained entrenched. Roman myths, many syncretized with Greek, reinforced the gender bias by which plants were associated with women. Chloris, Greek goddess of flowers, was assimilated to Flora, and Ceres to Demeter. Ovid recounts a story concerning Flora and Juno that symbolically connects flowers to parthenogenesis.

Abstract:

Chapter one describes “The Quandary Over Plant Sex” in its historical context. The sexual role of pollen wasn’t discovered until the late 17th century, suggesting a deep cultural bias. Beliefs concerning sex in humans, from Galen and Aristotle onward, were influenced by gender ideology. The lower social status of women suggested a one-sex model, whereby female character and physiology were construed as deficient versions of the male. Plants, because of their association with women, came to be regarded as female. Flowers are often emblematic of women in literature, but flowers seem to produce f

Abstract:

Abstract The irradiated pollen technique (IPT) is the most successful haploidization technique within Cucurbitaceae. The influence of gamma-ray doses (250, 350, 450 and 550 Gy), genotypes and stage of development of embryos obtained by IPT on the induction of haploid embryos were studied in several Iranian melon cultivars as well as their hybrids with alien cultivars. Female flowers were pollinated using pollen that had been irradiated with gamma rays. Different shapes and stages of embryos were excised 21-25 days after pollination and cultured on E20A medium. Direct culture, liquid culture and integrated culture methods were used; integrated culture and liquid culture methods showed advantages in increasing the efficiency of haploid plant production in melon breeding programmes. Results revealed that 550 Gy of gamma irradiation was successful in inducing parthenogenesis and fruit development, whereas lower irradiation doses were not effective in inducing haploid embryos. The percentages of embryos per seed were the highest in 'Samsoori' (1.2%) and 'Saveh' (1.1%) cultivars. Some of the heart-shaped and cotyledon-shaped embryos developed into haploid plants. In total, 52 parthenogenic melon plantlets were recovered from 274 embryos via IPT. Production of haploid embryos and haploid plants was strongly influenced by gamma-ray dose, embryo stage and genotype. Indirect methods and chromosome counting performed on the root cells of regenerated plants showed that these plants were haploid (n = x = 12).

Abstract:

Insect pests act as main barrier in enhancing yield potential of Brassica crops. Lipaphis erysimi is considered as one of the most destructive insect species in mustard production due to its voracious type feeding and multiplication. Therefore application of insecticide is inevitable for cultivation of cruciferous crops, although systemic insecticides has been found to be suitable for management of aphid, despite of high cost, residual effect and ecological ramification have necessitated the application of bio and botanical insecticides as novel approach and are recorded significant in research. Aphids having exclusively viviparous parthenogenesis type reproduction from January to March month with the completion of eight generations are helpful in quick mass multiplication. Natural enemies Coccinella spp., Syrphid larvae and bio-pesticide found effective in suppress aphid numbers. Manipulation in sowing dates of mustard crop provides good yield and less incidence of aphid which is proved through research. Lack of environmental resistant varieties has dispensed toward non feasibility of conventional breeding approaches for developing aphid-resistant Brassica. Although application of genetic engineering plan has resulted in moderate success in development of aphid resistance, so far commercialization of such genetically modified crops has not conceivable, intimate the necessity of further insights in to host plant and aphid communication to form effective approach against aphid resistance. Therefore in this chapter the components involved in Brassica aphid communication are highlighted and present statuses and problem in aphid management are discussed.
