The variations in leaf traits of Taxus species in different light conditions are still poorly understood. We sampled leaves of Taxus yunnanensis W. C. Chang L. K. Fu and Taxus chinensis var. mairei (Lemée and Lév.) W. C. Cheng and L. K. Fu along an illumination gradient (full daylight, 40–60% full daylight, <10% full daylight), and analyzed how seven leaf traits and their correlations changed under different light conditions. The leaf trait that showed the greatest variation was specific leaf area (SLA) for T. yunnanensis, followed by leaf dry mass (LM) for both taxa. The smallest variation was in leaf width (LW) for both taxa. Plasticities of all leaf traits in both taxa were higher than 50%, and those of leaf area (LA), LM and SLA were greater than 80%. The light gradient was positively correlated with leaf length (LL), LM, leaf dry matter content (LDMC), and leaf length to width ratio (LWR). LW and SLA were negatively correlated with the light gradient. Analyses of relationships among leaf traits showed that LM of T. yunnanensis, T. chinensis var. mairei and both taxa was positively correlated with LL, LW, LA, LDMC, and LWR, and negatively correlated with SLA under all light conditions. We concluded that leaf traits and their relationships were affected by light conditions.

Interleukin-15 (IL-15) is a cytokine that has been proposed to modulate skeletal muscle and adipose tissue mass. In the present study, an F2 resource population of Gushi chickens crossed with Anka broilers was used to investigate the genetic effects of the chicken IL-15 gene. Two single nucleotide polymorphisms (SNPs) (g.31224G>A and g.31266T>G) were identified in exon 5 of the IL-15 gene by means of polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. Associations between the two SNPs and chicken fatness and muscle fiber traits were determined using linkage disequilibrium, haplotype construction, and association analysis. Both of the SNPs were associated with abdominal fat weight, leg muscle fiber diameter, and leg muscle fiber density (p < 0.05). Haplotypes of the two linked SNPs were associated with abdominal fat weight, fat thickness under the skin, and leg muscle fiber diameter (p < 0.05). The results suggested that the IL-15 gene might be associated with the causative mutation or the quantitative trait locus (QTL) controlling the fatness traits and muscle fiber traits in chickens.

A novel cDNA clone encoding a COR413- like gene was isolated by suppression subtraction hybridization and cDNA library screening from seaisland cotton (Gossypium barbadense). This gene (designated as GbCOR413, Accession number: AY761065) has a total length of 893 bp with an open reading frame of 600 bp, encoding a predicated polypeptide of 200 amino acids with a molecular weight of 22.74 kDa and a predicated pI of 9.2. Bioinformatics analyses revealed that this gene belonged to a novel stress-regulated multi-spanning transmembrane protein family without signal peptide. By means of semiquantities RT-PCR analysis, the expression of GbCOR413 under short-term cold treatment at 4℃, water submergence and abscic acid treatment was investigated. Our studies suggested that the cloned gene was a new member of COR gene family which was slowly responsive to cold stress in cotton.
