Terpenes are the largest and most diverse class of secondary metabolites in plants and play a very important role in plant adaptation to environment. 3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is a rate-limiting enzyme in the process of terpene biosynthesis in the cytosol. Previous study found the HMGR genes underwent gene expansion in Gossypium raimondii, but the characteristics an...

ACCORDING to STEPHENS (1950) speciation in the genus Gossypium occurs both by cryptic structural differentiation of chromosomes and by major gene substitution and mutation. In the first paper of this series RHYNE (1958) reported a sizeable reduction of recombination values within linkage groups following a transfer of intact diploid Gossypium linkage groups into allotetraploid G. hirsutum. Thes...

Plant non-specific lipid transfer proteins (nsLTPs) are involved in many biological processes. In this study, 51, 47 and 91 nsLTPs were identified in Gossypium arboreum, G. raimondii and their descendant allotetraploid G. hirsutum, respectively. All the nsLTPs were phylogenetically divided into 8 distinct subfamilies. Besides, the recent duplication, which is considered cotton-specific whole ge...

Gossypium hirsutum L. is the predominant cotton of commerce and all cultivars of this species are susceptible to the reniform nematode, Rotylenchulus reniformis. To introgress resistance to R. reniformis into the tetraploid 2(AD1) G. hirsutum, a resistant diploid A2-genome Gossypium arboreum accession (A2190) was crossed with a hexaploid 2((AD1)D4) bridging line (G 371) to obtain a tetraploid t...

Investigation of Genetic Diversity and Identification Superior Cotton Cultivars (Gossypium Hirsutum L.) using SIIG Index

Calcineurin B-like (CBL) proteins, as calcium sensors, play pivotal roles in plant responses to diverse abiotic stresses and in growth and development through interaction with CBL-interacting protein kinases (CIPKs). However, knowledge about functions and evolution of CBLs in Gossypium plants is scarce. Here, we conducted a genome-wide survey and identified 13, 13 and 22 CBL genes in the progen...

Kapas Gossypium hirsutum adalah anggota keluarga Malvaceae, dan biji serta daunnya telah banyak digunakan untuk perawatan kesehatan. G. memiliki metabolit sekunder berupa flavonoid, tanin, saponin steroid yang dapat memberikan efek farmakologis. Penelitian ini bertujuan mengetahui perbandingan toksisitas antara ekstrak etanol daun kersen (Muntingia calabura) kapas (Gossypium hirsutum) menggunak...

The centromere is a repeat-rich structure essential for chromosome segregation; with the long-term aim of understanding centromere structure and function, we set out to identify cotton centromere sequences. To isolate centromere-associated sequences from cotton, (Gossypium hirsutum) we surveyed tandem and dispersed repetitive DNA in the genus. Centromere-associated elements in other plants incl...

WHORLED mutant in G. herbaceum has been reported from the Agricultural A Research Station, Surat, Bombay State, India, by CHAVDA and PATEL (1954). It had some phenotypic resemblance to the cluster-short branch mutant reported previously (PATEL, MUNSHI, and PATEL, 1947) the important common characteristic being short one-noded fruiting branches terminating in more than one flower bud. While the ...

Thirty volunteer subjects were exposed to controlled amounts of respirable dust generated by the carding of cotton in an experimental cardroom. Eighteen exposures each lasting six hours were performed while carding unwashed and washed cottons from the three major growing regions of the United States. Elutriated dust was analysed gravimetrically and was comparable (0.59 mg/m3 +/- 0.04) for all e...
