Adventitious root primordia formation and development in the stem of var. slip.

There are about 4-6 slips on a fruit, and they are good materials for effective regeneration of var. . Adventitious root (AR) induction is essential for the propagation of slips.

Screening and characterization of long noncoding RNAs involved in the albinism of Ananas comosus var. bracteatus leaves.

Long noncoding RNAs (lncRNAs) have been reported to play key regulatory roles in plant growth, development, and biotic and abiotic stress physiology. Revealing the mechanism of lncRNA regulation in the albino portions of leaves is important for understanding the development of chimeric leaves in Ananas comosus var. bracteatus.

SMRT sequencing analysis reveals the full-length transcripts and alternative splicing patterns in var. .

Background: var. is an herbaceous perennial monocot cultivated as an ornamental plant for its chimeric leaves. Because of its genomic complexity, and because no genomic information is available in the public GenBank database, the complete structure of the mRNA transcript is unclear and there are limited molecular mechanism studies for var.

[The effects of Kangai injection on enzyme activities of macrophages in rats].

Objective: To study the effects of Kangai injection on the enzyme activities of macrophages and morphology of spleen and thymus from rats.

Methods: Twenty four male SD rats were randomly divided into two groups (n = 12), normal control group and experimental group. The rats in experimental group were injected with Kangai injection at the dosage of 5 ml/kg x d for 30 days peritoneally and those in control group were injected with nomal saline at the same volume.
