Competitive and cooperative behavior of cells in angiosperms microsporogenesis
, 2016 Aim. A comparative cytological analysis of intra- and intertissue cytomictic interactions in early microsporogenesis of mono- and dicotyledonous plants was performed using two cellular systems: microsporocytes and tapetum. Methods.

Premeiotic microsporocyte cell shape influences shape of tetrads during microsporogenesis
, 2012 Angiosperm microspores are grouped into tetrads before they mature into functional pollen grains. This tetrad stage is an important step in microsporogenesis. Tetrad shapes are diverse across angiosperms, with high levels of variation sometimes occurring

Meiotic index in Myrtaceae native fruits trees from southern Brazil
Crop Breeding and Applied Biotechnology, 2004 This work aimed to evaluate meiotic index in Myrtaceae species, native of southern Brazil. Flower buds were collected and stored in ethylic alcohol:propionic acid (2:1) until evaluation by the smear and squash technique with propionic carmin as a dye.

Microsporogenesis in Brachiaria brizantha (Poaceae) as a selection tool for breeding. [PDF]
, 2018 The genus Brachiaria comprises more than 100 species and is the single most important genus of forage grass in the tropics. Brachiaria brizantha , widely used in Brazilian pastures for beef and dairy production, is native to tropical Africa. As a subsidy

High temperature injury and auxin biosynthesis in microsporogenesis
Frontiers in Plant Science, 2013 Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High temperature (HT) injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to HT.

Diversity and evolution of microsporogenesis in basal angiosperms and monocots
, 2013 Le grain de pollen, gamétophyte mâle, est le produit de la méiose mâle. Il présente une structure extrêmement diversifiée chez les Angiospermes. Afin d’étudier cette diversité, nous avons centré notre étude sur le type apertural. Défini par le nombre, la

Abnormal cytokinesis in microsporogenesis of Brachiaria humidicola (Poaceae: Paniceae). [PDF]
, 2018 Microsporogenesis was evaluated in the Brachiaria humidicola collection of the Embrapa Beef Cattle Center, represented by 60 acessions. One acession (H121) presented an abnormal pattern of cytokinesis that had never been reported in this genus. Among 900

Meiotic irregularities in Capsicum L. species
Crop Breeding and Applied Biotechnology, 2012 Cytogenetic and pollen viability (PV) studies were performed in pepper accessions, Capsicum chinense and Capsicum baccatum. Irregularities such as laggard and univalent chromosomes, bridges, problems in the spindle fibers and cytomixis were observed ...
