Somatic Embryogenesis from the Leaf-Derived Calli of In Vitro Shoot-Regenerated Plantlets of 'Carola'.

Roses are one of the most important flowers applied to landscape, cut flowers, fragrance and food industries widely. As an effective method for plant reproduction, the regeneration via somatic embryos is the most promising method for breed improvement and genetic transformation of woody plants. However, lower somatic embryogenesis (SE) induction rates and genotypic constraints impede progress in genetic transformation in rose.

Colchicine-Induced Tetraploidy in Protocorms of Lodd. ex Lindl. and Paxton. and Its Identification.

(Orchidaceae) boasts high ornamental value due to its pleasant aroma, foxtail spike, and elegant floral morphology. Inducing to become tetraploid enhances horticultural traits and facilitates fertile intergeneric hybrids through crosses with other market-available tetraploid species. The experimental design involved the application of colchicine at varying concentrations-0.

PeFtsH5 negatively regulates the biological stress response in Phalaenopsis equestris mitochondria.

Mitochondrial homeostasis plays a crucial role in determining cell fate by direct influence on cell apoptosis and autophagy. The ATP and Zn-dependent protease FtsH are of paramount importance in maintaining mitochondrial homeostasis. In Phalaenopsis equestris, three mitochondrial FtsH proteases were identified, one of which was encoded by the PeFtsH5 gene.

Induction of 2n pollen with colchicine during microsporogenesis in .

The induction of 2n pollen is an important technique for breeding polyploid plants. Here, we observed meiosis in the pollen mother cells (PMCs) of six cultivars and attempted to induce 2n pollen. The meiotic stage was related to flower bud length.

Characterization of Three Like MADS-Box Genes Associated With Floral Development in (Orchidaceae).

(Orchidaceae) is one of the world's most popular orchids that is found in tropical and subtropical forests and has an enormous ornamental value. like (like) MADS-box genes are responsible for floral organ specification. In this study, three like MADS-box genes, , , and , were identified in .

Effects of Comprehensive Swallowing Intervention on Obstructive Sleep Apnea and Dysphagia After Stroke: A Randomized Controlled Trial.

Objective: This study aims to explore the effects of comprehensive swallowing intervention on obstructive sleep apnea (OSA) and dysphagia in stroke patients.

Methods: We performed a randomized controlled trial in stroke patients with obstructive sleep apnea (OSA) complicated by dysphagia, divided into treatment group and control group. The treatment group underwent comprehensive swallowing intervention and received swallowing care for 4 weeks, while the control group received only swallowing care.

Development and characterization of polymorphic EST-SSR markers for (Orchidaceae).

Premise Of The Study: Microsatellite primers were developed for (Orchidaceae), a species threatened with extinction, to assess genetic diversity and population genetic structure.

Methods And Results: Based on the transcriptome data of , 34 novel polymorphic microsatellite expressed sequence tag-simple sequence repeat markers were developed and characterized in 33 individuals from two populations. The results showed the number of alleles per locus ranged from two to four, and levels of observed and expected heterozygosity per locus ranged from 0.

The AGL6-like gene OsMADS6 regulates floral organ and meristem identities in rice.

Although AGAMOUS-LIKE6 (AGL6) MADS-box genes are ancient with wide distributions in gymnosperms and angiosperms, their functions remain poorly understood. Here, we show the biological role of the AGL6-like gene, OsMADS6, in specifying floral organ and meristem identities in rice (Oryza sativa L.).
