Analysis of fiber quality lncRNAs and their target genes from a pair of Gossypium mustelinum near-isogenic lines provide new prospects for improving the fiber quality of Upland cotton. Long noncoding RNAs (lncRNAs) are an important part of genome transcription and play roles in a wide range of biological processes in plants. In this research, a pair of near-isogenic cotton lines, namely, a Gossypium mustelinum introgression line (IL9) with outstanding fiber quality and its recurrent Upland cotton parent (PD94042), were used as the experimental materials.

Results: In the current research, genome-wide identification was performed, and a total of 75 GGPS family members were found in four cotton species, Gossypium hirsutum, Gossypium barbadense, Gossypium arboreum and Gossypium raimondii. The GGPS genes were divided into three subgroups by evolutionary analysis.
Article Synopsis
- CLASPs are proteins that interact with microtubules, crucial for plant growth, yet little is known about their role in upland cotton specifically.
- This study conducted a genome analysis of the CLASP_N gene family in upland cotton, utilizing bioinformatics tools and real-time PCR to investigate their characteristics and expression patterns.
- The research identified 16 CLASP_N genes, noted their chromosomal locations, and revealed that they are highly expressed during later stages of fiber development, paving the way for further investigation of their molecular functions in cotton.
Objective: To investigate and analyze the occurrence of 64,101 perinatal birth defects from 2000 to 2004, to determine the tendency of the incidence rate of birth defects and perinatal mortality, and to explore feasible and effective intervention strategy.
Methods: We investigated 64,101 perinatal infants who were born in 13 hospitals in Changsha from January 2000 to December 2004. The incidence rate of all birth defects, mortality of perinatal infants, the incidence rate of various kinds of birth defects, and the component rate of birth defects were analyzed.
