Abstract:
... MAIN CONCLUSION: This review highlights the most relevant and recent updated information available on the defense responses of selected hosts against Xanthomonas spp. Xanthomonas is one of the most important genera of Gram-negative phytopathogenic bacteria, severely affecting the productivity of economically important crops worldwide, colonizing either the vascular system or the mesophyll tissue o ...

Abstract:
... KEY MESSAGE: TaPGLP1, a chloroplast stromal 2-phosphoglycolate phosphatase of wheat, is an ATG8-interacting protein and undergoes autophagic degradation in starvation-treated wheat mesophyll protoplasts. Selective autophagy in plants has been shown to target diverse cellular cargoes including whole chloroplasts (Chlorophagy) and several chloroplast components (Piecemeal chlorophagy). Most cargoes ...

Abstract:
... Serial sectioning transmission electron microscopy (ssTEM) is a classical method of 3D reconstruction using serial sections obtained with an ultramicrotome. However, producing a long ribbon with homogeneity is difficult. Here, ultramicrotome movement was suspended after producing a ribbon of 15–30 serial sections (cutting intervals, 100 nm), and then, the ribbon was mounted on an individual one-sl ...

Abstract:
... Microphylls, simple leaves with a single vein and no leaf gap, are the typical lycophyte leaves. However, Selaginella schaffneri has complex veins. Structural features and phylogeny associated with this unusual venation have remained unknown. We studied the leaf, venation, spore structures, and phylogeny of S. schaffneri, with S. erythropus as a typical Selaginella for comparison. Leaf veins of bo ...

Abstract:
... Bundle sheath (BS) cells exhibit dramatically structural differences and functional variations at physiological, biochemical and epigenetic levels as compared to mesophyll (M) cells in maize. The regulatory mechanisms controlling functional divergences between M and BS have been extensively investigated. However, BS cell-related regulatory networks are still not completely characterized. To addres ...

Abstract:
... The study presents leaf anatomy of 30 species of Eriocaulon (Eriocaulaceae) from India and Brazil. Observations of the anatomical traits and multivariate analyses were carried out to investigate the correlation between life cycle, life form, and leaf anatomical features of Eriocaulon species. The leaf anatomical characters of amphibian and submerged species were more consistent compared to those o ...

Abstract:
... Past studies have established mesophyll diffusion conductance to CO₂ (gₘ) as a variable and significant limitation to plant photosynthesis under steady‐state conditions. However, the role of gₘ in influencing photosynthesis (A) during the transient period of light induction is largely unknown. We combined gas exchange measurements with laser‐enabled carbon isotope discrimination measurements to as ...

Abstract:
... The microscopic morphology of the leaves of six varieties of Vitis vinifera taken in the León Denomination of Origin is studied: the varieties Albarín Blanco, Malvasía, Mencía, Prieto Picudo, Tempranillo and Verdejo Blanco. The morphology is studied in two leaf fragments (basal and distal) related to the midvein, and parameters such as the thickness of the mesophyll and the stomatal density are me ...
mesophyll, etc ; acclimation; agronomy; cotton; flower buds; genotype; heat stress; photosynthesis; temperature; Show all 9 Subjects
Abstract:
... Cotton is often exposed to high temperatures during the reproductive stage, which can negatively affect its productivity. The objectives were to: i) test whether heat stress impacts during the reproductive stage on photosynthesis are due to instant temperature effects or to acclimation produced during the heat stress period, ii) evaluate the role of stomatal and mesophyll conductance on net photos ...

Abstract:
... Leaf anatomical traits are responsive to environmental factors and thus highly plastic in their development and biochemical function. However, how they vary across large geographical scales and the main driving factors remain unclear, especially for forest plants. Here, by combining field sampling with plant semi-thin sectioning methods, eight anatomical traits (including leaf epidermis and mesoph ...

Abstract:
... Plant galls are generated by the stimuli of gall-inducing organisms on their hosts, creating gall morphotypes that vary in color, shape, size, and tissue organization. Herein, we propose to compare the structural features of gall morphotypes on the superhost Croton floribundus (Euphorbiaceae) in order to recognize gall morphospecies, i.e., galls with similar shapes but different internal structure ...

Abstract:
... Sucrose is produced in leaf mesophyll cells via photosynthesis and exported to non-photosynthetic sink tissues through the phloem. The molecular basis of source-to-sink long-distance transport in cereal crop plants is of importance due to its direct influence on grain yield—pollen grains, essential for male fertility, are filled with sugary starch, and rely on long-distance sugar transport from so ...

Abstract:
... During multicellularization, plants evolved unique cell-cell connections, the plasmodesmata (PD). PD of angiosperms are complex cellular domains, embedded in the cell wall and consisting of multiple membranes and a large number of proteins. From the beginning, it had been assumed that PD provide passage for a wide range of molecules, from ions to metabolites and hormones, to RNAs and even proteins ...

Abstract:
... Many plant leaves have two layers of photosynthetic tissue: the palisade and spongy mesophyll. Whereas palisade mesophyll consists of tightly packed columnar cells, the structure of spongy mesophyll is not well characterized and often treated as a random assemblage of irregularly shaped cells. Using micro‐computed tomography imaging, topological analysis, and a comparative physiological framework, ...

Abstract:
... The atmospheric concentration of carbon dioxide ([CO₂]) and oxygen ([O₂]) directly influence rates of photosynthesis (PN) and photorespiration (RPR) through the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO). Levels of [CO₂] and [O₂] have varied over Earth history affecting rates of both CO₂ uptake and loss, alongside associated transpirative water-loss. The availability of CO₂ h ...

Abstract:
... Poa alpigena is a dominant grass species in alpine meadows, which is sensitive to environmental conditions. In this study, we analyzed the characteristics of the anatomical structure of the stems and leaves of Poa alpigena in overgrazed and enclosed conditions in order to determine the dwarfing morphological mechanism associated with overgrazing. The results show that leaf thickness, leaf epiderma ...

Abstract:
... The epidermis is the first layer of cells on leaves that receive UV-B radiation and the place where guard cells distribute. Their stress response mechanism was different from the mesophyll. However, there has been little research on leaf epidermis. To assess the response mechanism of epidermis to UV-B radiation, tissue-specific proteomics were performed on the epidermis of Morus leaf under UV-B ra ...
