Ovules of Capsella bursa-pastoris at the dyad and tetrad stages of meiosis and at the megaspore and two-nucleate stages of the gametophyte were studied with the electron microscope. The cells of the dyad and tetrad are separated by aniline blue fluorescent cross walls and receive all types of organelles and autophagic vacuoles that were present in the meiocyte. Autophagic vacuoles enclose ribosomes and organelles and show reaction product for acid phosphatase. Autophagic vacuoles and some plastids are absorbed into the enlarging vacuoles of the growing megaspore. Other plastids appear to survive meiosis and there is no evidence for their de novo origin. Some mitochondria appear to degenerate in the enlarging megaspore but others look healthy and there is no evidence for the de novo origin of mitochondria. The nucleolus of the developing megaspore becomes very large and the cytoplasm is extremely dense with ribosomes. The cell wall is thickened by an electron-translucent, periodic acid – Schiff negative, aniline blue fluorescent material and contains plasmodesmata that link the megaspore with the nucellus. The plasmalemma of the growing megaspore produces microvilluslike extensions into this wall that disappear with the formation of the two-nucleate gametophyte. Plasmodesmata disappear from the cell wall at the four-nucleate stage.

The present study deals with the growth and development of the horn-shaped gall, which is induced by Schlechtendalia chinensis Bell. on leaves of Rhus chinensis Mill. The relationship between gall formers and their host plants was investigated by means of the activities of various invertases, the expressions of the cell wall invertase gene (INV2), and vacuolar invertase gene (INV3) during gall development. Our results show that the increase in the sink strength of the galls required cell wall invertase and vacuolar invertase, and that vacuolar invertase had a particular impact during the early development. In addition, vacuolar invertase activity was always significantly higher in galls than in leaves. However, ionically bound cell wall invertase showed a slightly significant increased activity level when compared with the leaves after galls had entered the fast growing period. This result indicates that vacuolar invertase is related to the rapid expansion of the galls, but ionically bound cell wall invertase is involved in the rapid growth of tissues. The enhanced activity of cell wall invertase and the expression of INV2 may be a plant response to a gall-induced stress. Cytoplasmic invertase that acts as a maintenance enzyme, or takes part in the production of secondary metabolites, was elevated when intracellular acid invertase activity decreased.

AbstractThe main objective of the present study was to clone, heterologously express and characterize a novel cell wall invertase (FCWI) from a Cu tolerant population of Elsholtzia haichowensis. The full-length FCWI cDNA contained an open reading frame (ORF) of 1671 bp which encoded a 556-amino-acid protein. The theoretical molecular mass and pI of the deduced protein were 62.5 kDa and 9.29, respectively. Phylogenetic analysis showed that FCWI had a closer evolutionary relationship to cell wall invertase of dicot. FCWI was expressed in methylotrophic yeast Pichia pastoris and purified to near homogeneity. Recombinant FCWI enzyme had pH optima of 4.0 and temperature optima of 50◦C. Activity analyses in the presence of various metal cations indicated that FCWI was completely inhibited by Hg
