Epiphytic plants in the Bromeliaceae known as tank bromeliads essentially lack stems and absorptive roots and instead take up water from reservoirs formed by their overlapping leaf bases. For such plants, leaf hydraulic conductance is plant hydraulic conductance. Their simple strap-shaped leaves and parallel venation make them suitable for modeling leaf hydraulic conductance based on vasculatur...

background: many types of single-use blades are manufactured with different designs and materials. there have been several reports of difficulties in obtaining a view of the glottis with single-use laryngoscopes. the purpose of this prospective study was to compare the quickness and the success rate of endotracheal intubations with two different laryngoscope blades: disposable laryngoscope blad...

Using the method of geometric morphometrics contour image leaf blade Common plantain ( Plantago major ) was aligned along axis symmetry to answer question whether asymmetry and shape were influenced by environmental pollution vehicles climatic conditions. Procrustes distances showed that fluctuating higher in roadside populations 2019. In control populations, a mixture two types asymmetry, dire...

UNLABELLED PREMISE OF THE STUDY Extrafloral nectaries (EFNs) are structures that secrete nectar and protect plants against herbivores and pathogens. In Gentianaceae, these structures have been described in species of Calolisianthus, Fagraea, and Anthocleista and are important morphological markers for taxonomic and phylogenetic studies. To establish a foundation for further studies, we inves...

Arabidopsis flowers in long day (LD) in response to signals transported from the photoinduced leaf to the shoot apex. These LD signals may include protein of the gene FLOWERING LOCUS T (FT) while in short day (SD) with its slower flowering, signalling may involve sucrose and gibberellin. Here, it is shown that after 5 weeks growth in SD, a single LD up-regulated leaf blade expression of FT and ...

Blade outgrowth and region-specific cell differentiation are crucial events during the early development of plant leaves, and the progression of both of these events requires a normal adaxial-abaxial pattern. In a recent study, we had demonstrated that two WUSCHEL-RELATED HOMEOBOX (WOX) family genes, i.e., PRESSED FLOWER (PRS) and WOX1, act redundantly in blade outgrowth and adaxial-abaxial pat...

Tissue localizations of cytosolic glutamine synthetase (GS1; EC 6.3.1.2), chloroplastic GS (GS2), and ferredoxin-dependent glutamate synthase (Fd-GOGAT; EC 1.4.7.1) in rice (Oryza sativa L.) leaf blades were investigated using a tissue-print immunoblot method with specific antibodies. The cross-sections of mature and senescent leaf blades from middle and basal regions were used for tissue print...
