gossypium australe/protease

A full-length cotton cDNA,designated GhCtp, was isolated from Gossypium hirsutum L. by the PCR-based cDNA library screening. The cDNA encodes a polypeptide of 473-amino acid residues. Sequence alignment showed that GhCtp was highly homologous to a family of carboxyl-terminal proteases (Ctp) from

Cotton, a natural fiber producing crop of huge importance, is often prone to attack of Verticillium dahliae. Papain-like cysteine proteases (PLCPs) constitute a large family in plants and were proposed to involve in plant defense against pathogen attack in a number of studies. However, there

A 993-bp regulatory region upstream of the translation start codon of subtilisin-like serine protease gene was isolated from Gossypium barbadense. This (T/A)AAAG-rich region, GbSLSP, and its 5'- and 3'-truncated versions were transferred into tobacco and Arabidopsis after fusing with GUS or GFP.

Metacaspases (MCs) are cysteine proteases that are important for programmed cell death (PCD) in plants. In this study, we identified 89 MC genes in the genomes of four Gossypium species (Gossypium raimondii, Gossypium barbadense, Gossypium hirsutum, and

Cotton plants were genetically modified through the introduction of a synthetic gene that encodes a Bacillus thuringiensis insecticidal protoxin referred to as Cry1F(synpro). This protoxin is a chimeric, full-length delta-endotoxin of 130 kDa, comprised of the core toxin of Cry1Fa2 protein and parts

Experiments were conducted to determine if pretreatment of cotton (Gossypium hirsutum L.) plants resulted in differential in vitro stabilities of nitrate reductase (NR) activity. Although NR activity declines markedly during the second half of the daily light period, in vitro NR stability is not

Little is known about the assembly and turnover of cellulose synthase complexes commonly called rosettes. Recent work indicates that rosette assembly could involve the dimerization of CesA (cellulose synthase catalytic subunit) proteins regulated by the redox state of the CesA zinc-binding domain

Potato type I and II serine protease inhibitors are produced by solanaceous plants as a defense mechanism against insects and microbes. Nicotiana alata proteinase inhibitor (NaPI) is a multidomain potato type II inhibitor (pin II) that is produced at high levels in the female reproductive tissues of

Plant pathogenic fungi represent the largest group of disease-causing agents on crop plants, and are a constant and major threat to agriculture worldwide. Recent studies have shown that engineered production of RNA interference (RNAi)-inducing dsRNA in host plants can trigger specific fungal gene

The nitrogen (N) metabolism of the leaf subtending the cotton boll (LSCB) was studied with two cotton (Gossypium hirsutum L.) cultivars (Simian 3, low-K tolerant; Siza 3, low-K sensitive) under three levels of potassium (K) fertilization (K0: 0 g K2O plant(-1), K1: 4.5 K2O plant(-1) and K2: 9.0 g
