Comparative Transcriptional Profiling of Two Contrasting Barley Genotypes under Salinity Stress during the Seedling Stage

Table 1

The classification of the significantly changed probe sets related to signal transduction, transcription factors, and compatible and secondary metabolites.

Class description	No. of probes	Reverse expression of probes	No. of signal transductions	No. of transcription factors	No. of compatible and secondary metabolites
Upregulation in shoot	1090
In Hua 11	906		52 + 52	26 + 35	13 + 22
In Hua 30	685	2	11 + 52	6 + 35	10 + 22
Downregulation in shoot	763
In Hua 11	493		7 + 27	4 + 10	2 + 10
In Hua 30	611		27 + 27	10 + 10	3 + 10
Upregulation in root	864
In Hua 11	702		14 + 38	4 + 19	7 + 21
In Hua30	716	0	14 + 38	7 + 19	4 + 21
Downregulation in root	609
In Hua 11	461		5 + 25	2 + 14	4 + 12
In Hua 30	510		7 + 25	3 + 14	6 + 12

The number of probe sets up or down in shoot or root tissues of Hua 11 and Hua 30 in response to salt stress at level of 2-fold or more and a 𝑃 value <0.05 was shown in this list. The annotation of probe sets was obtained by the best BLASTX hit against UniProt, TIGR rice, and TAIR Arabidopsis database. Functional classifications are defined according to Jiang and Deyholos [61], Rai et al. [62], and Mazid et al. [63]. The number in front of + was represented as the no. of probe sets only regulated in Hua 11 or Hua 30; the number behind + was represented as the no. of probe sets regulated both at Hua 11 and Hua 30. The redundancies probe sets are included only once in this list.
