1. 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

2. [PROVISIONAL] Identification of histone methylation modifiers and their expression patterns during somatic embryogenesis in Hevea brasiliensis
Abstract Histone methylation plays a crucial role in various biological processes including from heterochromatin formation to transcriptional regulation. Currently, no information is available regarding histone methylation modifiers in the important rubber-producing plant Hevea brasiliensis. Here, we identified 47 histone methyltransferase (HMT) genes and 25

3. Somatic embryos from Phalaenopsis classic Spotted Pink (Orchidaceae) protocorms
RESUMO: O presente estudo buscou induzir a formação de embriões somáticos em protocormos do híbrido Phalaenopsis Classic Spotted Pink em dois estádios de maturação fisiológica aos 80 e 120 dias após a inoculação das sementes (DAIS). Os protocormos foram inoculados em meio ½ MS suplementado com 0,1 mg L-1 de ANA e 3 mg L-1 de TDZ. Aos 15 dias de

4. Clonal Arabica coffee resistant to Meloidogyne paranaensis and damage threshold on plants development
ABSTRACT: Plants of Coffea arabica Icatu IAC 925 germplasm show resistance to Meloidogyne paranaensis under field conditions, but with variable rates of segregation. One mother plant, IAC 3, of Icatu IAC 925 was evaluated under controlled conditions through the reaction of its clones, obtained by somatic embryogenesis. Reproduction of nematodes in clones wer

5. Genome-wide Analysis of LBD (LATERAL ORGAN BOUNDARIES Domain) Gene Family in Brassica rapa
ABSTRACT LOB (lateral organ boundaries)-domain proteins define a family of plant-specific transcription factors involved in developmental process from embryogenesis to seed production. They play a crucial role in shaping the plant architecture through coordinating cell fate at meristem to organ boundaries. Identification of LBD genes from Brassica rapa gen

6. Genetic evaluation of Pinus taeda clones from somatic embryogenesis and their genotype x environment interaction
Abstract The objective of this study was to evaluate the genotype x environment interaction and to estimate the genetic components of variance and mean using mixed models in early selection of 238 clones of Pinus taeda propagated by somatic embryogenesis. The experiment consisted of a complete blocks design, with 12 replications, with one plant per plot, in

7. Efficient In Vitro Somatic Embryogenesis and Plant Regeneration from Mature and Immature Embryos of Wheat ( Triticum aestivum L.)
ABSTRACT An efficient regeneration system is a pre-requisite for the application of genetic transformation and functional genomics study of important plants. In this study, the effect of different factors (plant growth regulators, casein hydrolysate, aspartic acid and ascorbic acid) on in vitro embryogenesis and regeneration of Arta, Bahar and Zagros cultiva

8. Tissue culture efficiency of wheat species with different genomic formulas
Abstract Ancient wheats are increasingly considered as valuable resources for genes of interest which could be analyzed and introduced into cultivated varieties by genetic engineering technologies. The first stage of biotechnological crop improvement consists of successful in vitro plant regeneration. Twelve wheat germplasms with different genomic formulas (

9. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w

10. Somatic embryogenesis in Acrocomia aculeata Jacq. (Lodd.) ex Mart using the thin cell layer technique
Considering the necessity of Acrocomia aculeata propagation for large-scale production, the aim of this study was to establish a somatic embryogenesis protocol using the thin cell layer (TCL) technique. Aerial parts of in vitro plants were transversally cut at the base into eight TCLs and placed in a culture medium for callus induction. The induction medium

11. 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

12. Detection of self-incompatible oilseed rape plants (Brassica napus L.) based on molecular markers for identification of the class I S haplotype
The selection of desirable genotypes with recessive characteristics, such as self-incompatible plants, is often difficult or even impossible and represents a crucial barrier in accelerating the breeding process. Molecular approaches and selection based on molecular markers can allow breeders to overcome this limitation. The use of self-incompatibility is an
