The genes like HKT-1, NHX-1, and Rab16A showed better response in Nonabokra than Pokkali.
Though the tolerant cultivar Pokkali also showed gene expression at the constitutive level, the induction was considerably high in the susceptible variety IR-29, especially for the genes like HKT-1, SAPK5, Rab16A, and OSBZ8).
The inducibility by ABA was clear from the gene expression pattern in both IR-29 and Pokkali, the genes like HKT-1, NHX-1, NAC-1, SAPK5, Rab16A, DREBP2, CRT/DREBP, and WRKY71 showing better response and SAPK7 or WRKY24 with feeble induction).
Researchers already identified several HKT-like genes in wheat, at least nine in rice, but unique in Arabidopsis and Physcomitrella patens, since TaHKT2 1 (originally named HKT1) was firstly isolated from wheat roots.
In a brief interview today, Mr. Li said that he was confident Pacific Century could inject Internet magic into Cable and Wireless HKT's utility-like phone business.
But with ferocious competition in this city's international and mobile-phone markets, Cable and Wireless HKT is looking like an exhausted and tarnished former monopoly.
A characteristic feature of HKT transporters is the channel-like Na+ transport activity in the presence of a large amount of Na+ (Gassmann et al. [1996]; Xue et al. [2011]), which could contribute to Na+ over-accumulation in plants.
Here, seven different gene families were selected for transcriptional profiling, and they were named as high-affinity K+ transporter (HKT), Na_H_exchanger (NHX), calmodulin, calcineurin B-like protein and its target kinase (CIPK), vacuolar H-translocating inorganic pyrophosphatase (VHP), dehydrin, and stress-responsive protein (SRP) families.
Like America Online and Time Warner in the United States, Pacific Century's bid for Cable and Wireless HKT dramatizes the gravity-defying levels of Internet stocks in Asia.
In theory HKT should be well placed to exploit this.
