Plasmodesmata (PD) are plant-special intercellular channels that allow fast and efficient communication between a plant cell and its immediate neighbors. PD contain complex membrane structures formed by the extension of the plasma membrane (PM) of two adjacent cells. These channels contain a central ...
Cell division in germlings and young filaments of Oedogonium is described. In one species, division proceeded as expected. The ring was formed at the apic... JD Pickett-Heaps - 《Protoplasma》 被引量: 49发表: 1972年 A model for dispersal of plant pathogens by rainsplash A mechanistic rando...
The decision to replicate its DNA is of crucial importance for every cell and, in many organisms, is decisive for the progression through the entire cell cycle. A comparison of animals versus yeast has shown that, although most of the involved cell-cycle regulators are divergent in both clades...
The study of plants could be undertaken at essentially every level of organization within biology, from that within a cell to the entire biosphere. To cover even the main theoretical questions on these diverse levels and the mathematical approaches used to analyse them would require several volumes...
Plants have relatively few cell types, but their specialized functions and their interactions are essential for physiology, development, and defense. The contributions of individual cells have been distinguished by methods including in situ reporting, cell sampling, and cell separation, thus far mostly ...
1b and Supplementary Fig. 1f,g), their transcriptomes were compared. The pitcher transcriptome was differentially enriched with cell cycle- and morphogenesis-related GO terms (Supplementary Table 22), which may reflect the morphological complexity of pitcher leaves. Although both developmental and ...
It was further assumed that the sum of the components of each xi equals that of y, which means that each animal and plant protein source sample has the same weight. For each plant protein source xi, its ratio is denoted as wi and thus, the AA profile of the mixed proteins can be ...
Cell totipotency and pluripotency are the cellular basis for plant regeneration. In 2005, plant cell totipotency was listed as one of the top 25 among the 125 of the most challenging scientific questions by <italic>Science</italic>. How t
It is generally agreed that for many viruses only a single infectious particle or infection unit is needed actually to infect a cell and give rise to the visible lesion (Boxall and MacNeill, 1974). Theoretical consideration of the dilution curve is consistent with these data. Experiments with ...
Vector-borne diseases in humans occur through snails, mosquitoes, fleas, ticks, lice, sandflies, and tsetse flies infected with microbes. These comprise ov
