NAC domain proteins are plant-specific transcription factors known to play diverse roles in various plant developmental processes. In the present study, we performed the first comprehensive study of the NAC gene family in Gossypium raimondii Ulbr., incorporating phylogenetic, chromosomal location, gene structure, conserved motif, and expression profiling analyses. We identified 145 NAC transcription factor （NAC-TF） genes that were phylogenetically clustered into 18 distinct subfamilies. Of these, 127 NAC-TF genes were distributed across the 13 chromosomes, 80 （55%） were preferentially retained duplicates located in both duplicated regions and six were located in triplicated chromosomal regions. The majority of NAC-TF genes showed temporal-, spatial-, and tissue-specific expression patterns based on tran- scriptomic and qRT-PCR analyses. However, the expression patterns of several duplicate genes were partially redundant, suggesting the occurrence of sub-functionalization during their evolution. Based on their genomic organization, we concluded that genomic duplications contributed significantly to the expansion of the NAC-TF gene family in G. raimondii. Comprehensive analysis of their expression profiles could provide novel insights into the functional divergence among members of the NAC gene family in G. raimondii.

Sucrose synthase （Sus） is a key enzyme in plant sucrose metabolism. In cotton, Sus （EC 2.***.1.13） is the main enzyme that degrades sucrose imported into cotton fibers from the phloem of the seed coat. This study demonstrated that the genomes of Gossypium arboreum L., G. raimondii Ulbr., and G. hirsutum L., contained 8, 8, and 15 Sus genes, respectively. Their structural organizations, phylogenetic relationships, and expression profiles were characterized. Comparisons of genomic and coding sequences identified multiple introns, the number and positions of which were highly conserved between diploid and allotetraploid cotton species. Most of the phylogenetic clades contained sequences from all three species, suggesting that the Sus genes of tetraploid G. hirsutum derived from those of its diploid ancestors. One Sus group （Sus I） underwent expansion during cotton evolution. Expression analyses indicated that most Sus genes were differentially expressed in various tissues and had development-dependent expression profiles in cotton fiber cells. Members of the same orthologous group had very similar expression patterns in all three species. These results provide new insights into the evolution of the cotton Sus gene family, and insight into its members＇ physiological functions during fiber growth and development.

Resurrection plants are tolerant to extreme dehydration and are useful model systems to study genes that play a role in drought tolerance. A gene fragment encoding a dirigent protein that is predicted to function in lignin biosynthesis was identified from leaves of the resurrection plant Boea hygrometrica via cDNA microarray screening. A cDNA, designated BhDIR1, containing the complete predicted open reading frame, was obtained by 50-RACE. BhDIR1 transcripts were found to be accumulated in response to changes in plant dehydration status, exogenously applied phytohormones and signaling molecules, and temperature stresses. BhDIR1 encodes a protein of 199 amino acids, which shows 20-40% similarity to dirigent proteins reported from other plants. BhDIR1 is predicted to contain a cleavable signal peptide at the N-terminal, and its plasma membrane/cell wall localization was confirmed using a GFP fusion protein assay. Consistent with this discovery, the acid-soluble lignin content decreased in dehydrated B. hygrometrica leaves. Taken together, our results indicate a protective role for a dirigent protein in response to drought stress by changing the physical characters of lignin which in turn is predicted to affect the mechanical strength and flexibility of the plant cell wall.
