Chromosomal inactivation and reactivation in mealy bugs.
UNDERSTANDING genetic inactivation and reactivation in a developing organism is the key to understanding cytodifferentiation. One phenomenon which may help us formulate the proper questions about differentiation is the inactivation and reactivation of whole chromosomes or large segments of chromosomes during development. In this paper I am going to describe one such system of chromosomal modifi...
متن کاملThe effect of supernumerary chromosomes on the development of mealy bugs.
UPERNUMERARIES, or B chromosomes, were described from several populations of the mealy bug, Pseudococcus obscurus Essig (Homoptera: Coccoidea) , in California ( NIJR 1962~) . Cytological analysis and breeding experiments revealed that the supernumeraries undergo preferential segregation in both spermatogenesis and oogenesis (NUR 1962b). In male mealy bugs with the lecanoid chromosome system onl...
متن کاملGroups and Semigroups Defined by some Classes of Mealy Automata
Two classes of finite Mealy automata (automata without branches, slowmoving automata) are considered in this article. We study algebraic properties of transformations defined by automata of these classes. We consider groups and semigroups defined by automata without branches.
متن کاملIngestive Behavior of Heifers Feeding with Marandu Grass Silage
The present study was aimed at assessing the ingestive behavior of ¾ Zebu × Holstein heifers confined to different levels of substitution of sorghum silage by marandu grass silage. Twenty heifers were used with initial average weight of 346.25 kg, divided into completely randomized experimental design with 5 repetitions and the following treatments: treatment 1) roughage fraction of the diet co...
متن کاملIdentification and Management of Common Boll-Feeding Bugs in Cotton
1 This publication was developed to provide a summary of information about common boll-feeding bugs (heteropteran pests), stress proper identification of these pests, and acquaint the reader with the recommended strategies for management of boll-feeding bugs in cotton. The first section of this publication emphasizes the recent importance of boll-feeding bugs in cotton and provides a brief disc...
