Opis:
By means of microscopic analyses, it was shown that root nodules formed by Chamaecytisus podolicus exhibited all structural features typical for indeterminate nodules of temperate genistean shrubs: (i) apical nodule meristem composed of infected and non-infected domains, (ii) parenchymatous bacteroid-containing tissue with infected cells only resulting from mitotic activity of infected meristematic cells, (iii) absence of infection threads, and (iv) convoluted bacteroids singly enclosed in a symbiosome membrane. For the first time, it was shown that the nodule meristem is organized into longitudinal files of sister cells.
Na podstawie analiz przeprowadzonych metodami mikroskopowymi wykazano, że brodawki korzeniowe powstające u Chamecytisus podolicus mają wszystkie cechy strukturalne typowe dla brodawek o nieograniczonym wzroście wytwarzanych przez krzewy klimatu umiarkowanego należące do plemienia Genisteae: (i) merystem apikalny składający się z domen zainfekowanej i niezainfekowanej, (ii) miękiszową tkankę bakteroidalną zawierającą tylko komórki zainfekowane, wytwarzaną poprzez podziały mitotyczne komórek zainfekowanych merystemu, (iii) brak nici infekcyjnych oraz (iv) zwinięte bakteroidy występujące pojedynczo w symbiosomach. Po raz pierwszy wykazano, że w merystemie brodawki występują podłużnie ułożone ciągi komórek siostrzanych.

Opis:
Changes in the activity of acid phosphatase (AcPase) in the apoplast of pea root nodule were investigated. The activity was determined using lead and cerium methods. The results indicated a following sequence of AcPase activity appearance during the development of the infection thread: 1) low AcPase activity appears in the outer part of cells of symbiotic bacteria; 2) bacteria show increased AcPase activity, and the enzyme activity appears in the thread walls; 3) activity exhibits also matrix of the infection thread; 4) bacteria just before their release from the infection threads show high AcPase activity; 5) AcPase activity ceases after bacteria transformation into bacteroids. The increase in bacterial AcPase activity may reflect a higher demand for inorganic phosphorus necessary for propagation of the bacteria within the infection threads and/or involved in bacteria release from the infection threads.

Opis:
Using a sand pouch-plant infection method, populations of several species of root-nodule bacteria (rhizobia) were enumerated in eighty soils collected throughout Poland. Rhizobium leguminosarum bv. viciae (symbionts of pea, faba bean, vetch) and R. leguminosarum bv. trifolii (symbionts of clover) were detected in 77 and 76 soils, respectively. Most of these soils contained moderate and high numbers of these species of the rhizobia. Symbionts of beans, R. leguminosarum bv. phaseoli, were assessed in 76 soils; of this number 15 soils had no detectable populations of bean rhizobia and in 40 soils high or moderate numbers of these bacteria were found. Bradyrhizobium sp. (Lupinus), root-nodule bacteria of lupine and serradella, were absent in 19 soils, out of 80 tested, and 34 soils were colonised by high or moderate populations of bradyrhizobia. Sinorhizobium meliloti, rhizobia nodulating alfalfa, were sparse in the examined soils; with 56 soil containing no detectable numbers of S. meliloti and only 6 soils harbouring high or moderate populations of this species. The estimated numbers of the rhizobia in the studied soils were also related to some physical and chemical properties of these soils.

Opis:
Adults of Sitona humeralis Steph. damage leaves of alfalfa, causing bay-shaped leaf holes characteristic for the Sitona spp. The larvae damage root nodules, taproots and open the infection paths for pathogenic fungi which occur in soil and on the root surface which results in the withering of plants.
Chrząszcze S. humeralis uszkadzają liście lucerny, powodując zatokowe wżery blaszki liściowej charakterystyczne dla Sitona spp. Larwy tego owada uszkadzają brodawki korzeniowe, korzeń palowy oraz otwierają drogi zakażenia dla znajdujących się w glebie i na powierzchni korzenia patogenicznych grzybów, co w konsekwencji powoduje zasychanie roślin.

Opis:
Morphometric procedures were used to examine peroxisome number and di-stribution in pea (Pisum sativum L.) root nodules under NaCl (50 mM) or HgCl2 (7.3 µM) treatment. Peroxisomes were visualized cytochemically in meristem, invasion zone and prefixing zone of pea root nodules by catalase (EC 1.11.1.6) activity. The observations using light and electron microscopy revealed that the peroxisomes were predominantly spherical in shape and showed catalase activity. In nitrogen fixation zone, catalase active peroxisomes were observed occasionally. Bacteroids of nitrogen fixing zone showed enhanced cata-lase activity probably as a response to higher level of oxidative stress. Fluorescence microscopy investigations revealed enhanced level of (homo)glutathione in prefixing and nitrogen-fixing zone of NaCl- and Hg2+treated nodules, which served as an indicator of antioxidative response. Morphometric measurements revealed that during differentiation of meristematic cells into central tissue (bacteroidal tissue) cells an increase in peroxisome number was observed in unstressed nodules. Peroxisomes located in meristem, invasion zone and prefixing zone of NaCl- and Hg2+-treated nodules outnumbered that in control nodules. A substantial enlargement of peroxisome profiles was detected in NaCl- and Hg2+treated nodules. Peroxisome divisions observed in meristematic and infection thread penetration zone were responsible for an increase in peroxisome number.

Opis:
Vacuoles play very important physiological roles in plant cells. Pea root nodules, which exhibit distinct zonation (meristematic zone and central tissue zones), may serve as a good experimental model for the investigations of vacuole development and its importance to cell and tissue functioning. Moreover, the nodule central tissue is composed of both infected and uninfected cells which play different physiological roles and differ in the level of vacuolation. Cytological observations revealed that central vacuoles of the infected cells of the effective nodules expand toward cell walls. Thus only thin layers of the cytoplasm separate each central vacuole from plasma membrane and cell wall. This finding is discussed from the viewpoint of improved exchange of solutes and water between the central vacuole and apoplast of the infected cell. Three-dimensional reconstruction of the vacuoles of infected cells within a fragment of effective nodule central tissue, showed their spatial arrangement. Possible advantages coming from the spatial arrangement of vacuoles within the central tissue are discussed. A comparative study of the central tissue (bacteroidal tissue) and meristem vacuolation of the effective and ineffective pea root nodules is also presented. Morphometric measurements revealed that the effective nodule central tissue was more vacuolated than the ineffective one. It was proved that maturation of the infected cells involves dynamic changes in their vacuolation. Having numerous fixing nitrogen bacteroids, the infected cells of effective central tissue were less vacuolated than uninfected cells. On the other hand, both infected and uninfected cells of the effective central tissue showed a much higher level of vacuolation in nitrogen-fixing zone than cells of the same type in ineffective tissue. These results indicate that vacuolation is an important factor in development and functioning of pea root nodule central tissue.
