2. Anatomical and histochemical studies of the somatic embryogenesis of Syagrus oleracea from immature inflorescences
Abstract Anatomical and histochemical studies were carried out during the somatic embryogenesis of Syagrus oleracea (Mart.) Becc. from immature inflorescences. Immature rachillas were inoculated on Murashige and Skoog medium with 4.52 μM 4-amino-3,5,6-trichloropicolinic acid (Picloram) and 2,4-diclorophenoxyacetic acid. Auxin concentrations were gradually r

3. AUXIN PULSE IN THE INDUCTION OF SOMATIC EMBRYOS OF Eucalyptus
RESUMO O objetivo do estudo foi avaliar o efeito de intervalos de pulsos de auxina na indução de embriões somáticos de Eucalyptus grandis x E. urophylla e a descrição do comportamento embriogênico de calos sob efeito do estresse auxínico. Cotilédones foram inoculados em meio de cultura contendo 207,07 µM de picloram, tratamento considerado como pul

4. HISTOLOGICAL ANALYSIS OF INDIRECT SOMATIC EMBRYOGENESIS INDUCED FROM ROOT EXPLATS OF OIL PALM (Elaeis guineensis Jacq)
RESUMO O dendezeiro é economicamente importante pela alta produção de óleo. A embriogênese somática indireta em dendezeiro demanda longo tempo de indução de calos e formação das plantas, sendo importante o estudo do potencial embriogênico dos calos e os mecanismos da embriogênese somática. O objetivo deste estudo foi verificar o efeito de difere

5. Somatic embryogenesis in the commercial papaya hybrid UENF/Caliman 01 relying on plantlet production from sexed adult hermaphrodite donor plants
Abstract: Somatic embryogenesis from explants from hermaphrodite papaya mother plants is an alternative for the production of true-to-type plants without the need for sexing. This study aimed to analyze hormonal and osmotic inducers in different somatic embryogenesis stages in the commercial hermaphrodite hybrid papaya UENF/Caliman 01. Leaf disks from in vit

6. Morpho and Cytological Differentiation of Calli of Eucalyptus grandis x Eucalyptus urophylla During Somatic Embryogenesis
ABSTRACT The aim of this study was to induce and analyze embryogenic calli from two types of explants (leaves and meristems) of the hybrid Eucalyptus grandis x Eucalyptus urophylla. Leaves and meristems of plants kept in a nursery were disinfected and inoculated in Petri dishes containing MS culture medium supplemented with different concentrations of the gr

7. Somatic embryogenesis in Carica papaya as affected by auxins and explants, and morphoanatomical-related aspects
ABSTRACT The aim of this study was to evaluate somatic embryogenesis in juvenile explants of the THB papaya cultivar. Apical shoots and cotyledonary leaves were inoculated in an induction medium composed of different concentrations of 2,4-D (6, 9, 12, 15 and 18 µM) or 4-CPA (19, 22, 25, 28 and 31 µM). The embryogenic calluses were transferred to a maturati

8. Genetic analysis of reciprocal differences in the inheritance of in vitro characters in pearl millet
Abstract Reciprocal differences persist in nature because of the unequal contribution of cytoplasmic determinants from male and female gametes to the zygote. The inheritance of genetic differences is an important factor that influences various traits, including somatic embryogenesis and regeneration in vitro. In this report, we estimate the cytoplasmic and m

9. Characterization of the third SERK gene in pineapple (Ananas comosus) and analysis of its expression and autophosphorylation activity in vitro
Two somatic embryogenesis receptor-like kinase genes (identified as AcSERK1 and AcSERK2) have previously been characterized from pineapple (Ananas comosus). In this work, we describe the characterization of a third gene (AcSERK3) in this family. AcSERK3 had all the characteristic domains and shared extensive sequence homology with other plant SERKs. AcSERK3

10. Somatic embryogenesis and plant regeneration in Wedelia calendulacea Less. an endangered medicinal plant
In this work, plant regeneration via somatic embryogenesis was achieved from leaf and internode derived callus of Wedelia calendulacea, an endangered medicinal plant. Primary callus was induced by culturing leaf disc and internode explant on Murashige and Skoog medium supplemented with 2.0 mg L-1 of 2,4-D under light condition. Transfer of embryogenic callus

11. Polyethylene glycol effects on somatic embryogenesis of papaya hybrid UENF/CALIMAN 01 seeds
Among commercial fruits, papaya (Carica papaya L.) is notably one of the most common ones around the world. The aim of the current study was to establish a somatic embryogenesis protocol for the hybrid UENF/CALIMAN 01, elucidating the effects of sucrose and 2,4-dichlorophenoxyacetic acid (2,4-D) on the induction of embryogenic cultures and the effect of poly

12. Cultura de anteras e partenogênese in situ e in vitro de genótipos de laranja doce (Citrus sinensis Osbeck.) / Anther culture and in vitro and in situ parthenogenesis of sweet orange (Citrus sinensis Osbeck.) genotypes
The production of completely homozygous lines in citrus breeding program is hard, and double-haploid plantlets (completely homozygous lines) can be used to improve these breeding programs. However, many factors are associated with the success of the regeneration of haploid or double-haploid plants. The aim of this study was the induction and regeneration of
