Leaf primordia initiate from the shoot apical meristem with inherent polarity; the adaxial side faces the meristem, while the abaxial side faces away from the meristem. Adaxial/abaxial polarity is thought to be necessary for laminar growth of leaves, as mutants lacking either adaxial or abaxial cell types often develop radially symmetric lateral organs. The milkweed pod1 (mwp1) mutant of maize ...

Establishment of adaxial-abaxial polarity is essential for lateral organ development. The mechanisms underlying the polarity establishment in the stamen remain unclear, whereas those in the leaf are well understood. Here, we investigated a rod-like lemma (rol) mutant of rice (Oryza sativa), in which the development of the stamen and lemma is severely compromised. We found that the rod-like stru...

Anatomical characteristics regenerant plantlet of Arabica coffee (Coffea arabica L.) were observed to determine the difference performance between Sigararutang and Maragogige grown in shooting rooting medium. Transverse sections fresh roots, stems leaves three-month-old plantlets from somatic embryos collected used for study. Maragogipe as materials chosen based on bean size origin. Stomata mic...

Bach & Fortunato, Desmodium incanum DC.y Rhynchosia edulis Griseb. provenientes las Sierras Chicas Córdoba. Se analizó estructura anatómica cinco ejemplares cada especie, con preparados temporarios y se tomaron fotomi...

Acanthaceae or the Acanthus family has been commonly used by local peoples as traditional medicines, especially in PeninsularMalaysia. Justicia gendarussa, also known ‘daun rusa’ ‘genda rusa,’ treats inflammatory disorders, asthma, hepatic injuries,arthritis, and digestion problems. Many taxonomists nowadays struggle to identify species due morphologicalsimilarities incomplete parts during iden...

The understanding of the behavior each cultivar under adverse climatic conditions is important in choice plants that best fit region to be inserted. Due large number cultivars available on market it makes difficult for producers choose which material plant. In view above, this study aimed know morphophysiological characteristics coffee. experimental design was randomized blocks with 10 treatmen...

A defining feature of plant leaves is their flattened shape. This shape depends on an antagonism between the genes that specify adaxial (top) and abaxial (bottom) tissue identity; however, the molecular nature of this antagonism remains poorly understood. Class III homeodomain leucine zipper (HD-ZIP) transcription factors are key mediators in the regulation of adaxial-abaxial patterning. Their ...
