Lantana camara L. is an economically important essential oil producing plant belonging to family Verbenaceae. It is used in medication for treating various diseases like cancer, ulcers, tumor, asthma and fever. The plant is a useful source of essential bioactive compounds such as steroids, flavonoids and phenylpropanoid glycosides etc. Nonetheless, very little is known about the genomic or transcriptomic resources of L. camara , and this might be the reason of hindering molecular studies leading to identification of improved lines. Here we used Illumina sequencing platform and performed the L. camara leaf (LCL) and root (LCR) de novo transcriptome analyses . A total of 70,155,594 and 84,263,224 clean reads were obtained and de novo assembly generated 72,877 and 513,985 unigenes from leaf (LCL) and root (LCR) respectively. Furthermore, the pathway analysis revealed the presence of 229 and 943 genes involved in the phenylpropanoid biosynthesis in leaf and root tissues respectively. Similarity search was performed against publically available genome databases and best matches were found with Sesamum indicum (67.5%) that were much higher than that of Arabidopsis thaliana (3.9%). To the best of our knowledge, this is the first comprehensive transcriptomic analysis of leaf and root tissues of this non-model plant from family Verbenaceae and may serve as a baseline for further molecular studies.

The aim of the study was to isolate and identify the most salt-tolerant endophytic bacteria from the mangrove plants (Avicennia marina) from the Red Sea Jeddah coastal region. In total, 21 endophytic bacteria were isolated from various parts of Avicennia marina cultured under various salt concentrations in laboratory conditions. Out of 21 endophytes, one isolate was selected based on its salt tolerance capacity, the isolate was identified as Bacillus halotolerans using 16S rRNA sequencing. The nucleotide sequence has been deposited under accession number MT858957. Bacillus halotolerans ymk 021 grows under high salinity and temperature. In response to high salinity stress (550 mM) mung bean (Vigna radiata L.) treated with B. halotolerans ymk021 showed significant results in morphological characteristics like fresh root and shoot weight, dry root and shoot weight, and root and shoot length. The ability of this salt-tolerant bacterial endophyte to produce antioxidants in plant may also resolve the major issue of oxidative damage during salinity stress. It may produce antibiotics, essential industrial enzymes too.
