TLDR
El presente estudio muestra that the aleta de las semillas de H. Lhotzkyana se desarrolla a partir del rafe and consists of parenchymatic cells sourronding the rapheal vascular bundle and both sclerenchymatic epidermis.Abstract:
Fueron estudiadas la anatomia y la ontogenia de las semillas de H Lhotzkyana, con el fin de conocer la estructura y el origen de su aleta Fueron analizadas semillas maduras de H baruensis, representante del genero, con el fin de comparar los dos tipos de semillas La exotesta esta constituida por esclereidas alargadas longitudinalmente, la endotesta esta formada por celulas parenquimaticas con pequenos grupos de celulas taniferas El principal mechanical layer de la semilla es el exotegmen, formado por macroesclereidas radialmente alargadas, el meso y endotegmen son taniniferos El presente estudio muestra que la aleta de las semillas de H Lhotzkyana se desarrolla a partir del rafe, and consists of parenchymatic cells sourronding the rapheal vascular bundle and both sclerenchymatic epidermisread more

Somatic embryogenesis and plant regeneration from immature zygotic embryos of Melia azedarach (Meliaceae)
TL;DR: A large number of plants were regenerated from somatic embryos and successfully established in soil in a greenhouse, which may be beneficial for mass propagation as well as for genetic manipulation of the ‘paradise tree’.

Thidiazuron Promotes In Vitro Plant Regeneration of Arachis correntina ( Leguminosae ) via Organogenesis
TL;DR: Investigation of plant regeneration potential of mature leaves of A. correntina in tissue culture revealed that shoots regenerated via organogenesis, and the development of new A. Correntina cultivars with improved traits could be facilitated through the application of biotechnological strategies.

Anatomical structure and secretion compounds of colleters in nine Ilex species (Aquifoliaceae) from southern South America
TL;DR: In this paper, the glandular origin of the stipular colleters in Ilex is confirmed on the basis of their position, secretions and anatomy, and proteins were found in the secretions studied.

Colleters in Turnera and Piriqueta (Turneraceae)
TL;DR: The anatomy of colleters was examined by light and scanning electron microscopy in 25 species of Turnera and nine species of Piriqueta, finding the first record of sessile, lachrymiform and trochleariform colleters.

In vitro cultured primary roots derived from stem segments of cassava (Manihot esculenta) can behave like storage organs.
TL;DR: The storage root formation system reported here is a first approach to develop a tuberization model, and additional efforts are required to improve it.
