Nesse contexto, o objetivo do presente estudo foi avaliar a qualidade da fibra do algodoeiro BRS verde, usando níveis de salinidade da água de irrigação. O experimento foi realizado em condições de campo na Fazenda Experimental Rafael Fernandes, de propriedade da Universidade Federal Rural do Semiárido­–UFERSA no período 21/10/11 até 06/02/12. O delineamento experimental adotado foi em blocos casualizados com seis tratamentos e cinco repetições, totalizando 30 parcelas experimentais. Os tratamentos resultaram das combinações de três tipos de condutividade elétrica da água de irrigação (S1- 0,55; S2-2,16 e S3-3,53 dS m-1) de acordo com as fases de desenvolvimento da cultura (T1- S1S1S1; T2- S2S2S2; T3- S3S3S3; T4- S1S2S2; T5- S1S2S3 e T6- S1S3S3), sendo a primeira fase do semeio até 30 dias; a segunda fase inicia-se dos 31 aos 90 dias; e a terceira fase dos 91 a colheita. As variáveis analisadas foram: porcentagem de fibra, comprimento da fibra, uniformidade do comprimento, maturidade, resistência, índice micronaire, índice de fibras curtas, elongação de ruptura e índice de fiabilidade. No geral, não houve efeito da salinidade da água de irrigação sobre a qualidade de fibra do algodão BRS verde, exceto para a característica elongamento da ruptura (ELG). Deste modo, torna-se viável o uso de água com salinidade de (3,5 dS m-1) em todo o ciclo da cultura considerando as condições de realização do estudo. Palavras-chave: Gossypium hirsutum L..

In this context, the aim of this study was to evaluate the quality of the cotton fiber BRS green, using salinity levels of irrigation water. The experiment was conducted under field condition sat the Experimental Farm Rafael Fernandes, owned by Federal Rural University of the semiarid – UFERSA the period 21/10/11 to 06/02/12. The treatments consisted of combinations of three types of electrical conductivity of irrigation water (S1- 0,55; S2-2,16 and S3-3,53 dS m-1) according to the development stages of culture T1- S1S1S1; T2- S2S2S2; T3- S3S3S3; T4- S1S2S2; T5- S1S2S3; T6- S1S3S3, the first phase being 30 days from the sowing; the second stage starts from 31 to 90 days; and the third phase of the 91 harvest. The variables analyzed were: fiber percentage, fiber length, length uniformity, maturity, strength, micronaire, short fiber index, elongation at break and reliability index. Overall, there was no effect of irrigation water salinity on the fiber quality of cotton BRS green, except for the elongation characteristic of rupture (ELG). Thus, it becomes feasible to use water with salinity (3,5 dS m-1) throughout the crop cycle considering the conditions of the study. Keywords: Gossypium hirsutum L..

WRKY transcription factors had multiple functions in plant secondary metabolism, leaf senescence, fruit ripening, adaptation to biotic and abiotic stress, and plant growth and development. However, knowledge of the group III WRKY subfamily in fiber development in upland cotton (Gossypium hirsutum L.) is largely absent. Previous studies have shown that there were 21 putative group III WRKY members in G. hirsutum L. These putative amino acid sequences from the III WRKY group were phylogenetically clustered into three clades. Multiple alignment, conservative motif analysis, and gene structure analysis showed that the members clustered together in the phylogenetic tree had similar motifs and gene structures. Expression pattern analysis revealed that variation in the expression levels of these genes in different tissues and fiber development stages. To better understand the functions of putative group III WRKY genes in G. hirsutum L., we selected the cotton fiber initiation-related gene GhWRKY53 for cloning and functional identification. The subcellular localization experiment of GhWRKY53 in Nicotiana tabacum leaves showed that it was located in the nucleus. The heterologous expression of GhWRKY53 in Arabidopsis thaliana could significantly increase the density of trichomes. Twelve proteins that interacted with GhWRKY53 were screened from the cotton fiber cDNA library by yeast two-hybrid experiment. This study findings lay a foundation for further research on the role of the GhWRKY53 during cotton fiber development and provide a new insight for further studying putative group III WRKY genes in G. hirsutum L. Our research results also provide vital information for the genetic mechanism of high-quality cotton fiber formation and essential genetic resources for cotton fiber quality improvement.
