![]() This study reports the molecular mechanism of the ABA-dependent drought-escape response pathway. This mechanism might contribute to adaptation by enabling plants to complete their life cycles under drought stress. Taken together, these results suggest that ABF3 and ABF4 act with NF-YCs to promote flowering by inducing SOC1 transcription under drought conditions. Interestingly, the abf3 abf4, nf-yc3 yc4 yc9, and soc1 mutants displayed a reduced drought-escape response. We found that ABF3 and ABF4 interact with nuclear factor Y subunit C (NF-YC) 3/4/9 in vitro and in planta, and induction of SOC1 by ABA was hampered in nf-yc3 yc4 yc9 mutants. ABF3 and ABF4 were enriched at the −1028- to −657-bp region of the SOC1 promoter, which does not contain canonical ABF-ABRE-binding motifs but has the NF-Y binding element. Moreover, induction of SOC1 by ABA was hampered in abf3 abf4 mutants. We identified SOC1 as a direct downstream target of ABF3/4, and found that SOC1 mRNA levels were lower in abf3 abf4 than in wild-type plants. Ectopic expression of ABF3 or ABF4 in the vasculature, but not in the shoot apex, induced early flowering, whereas expression of ABF3 fused with the SRDX transcriptional repressor domain delayed flowering. The abf3 abf4 mutant displayed ABA-insensitive late flowering under long-day conditions. Here, we show that Arabidopsis thaliana ABF3 and ABF4 regulate flowering in response to drought through transcriptional regulation of the floral integrator SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1). Abscisic acid (ABA) mediates plant responses to drought, but the role of ABA-responsive element (ABRE)-binding factors (ABFs) in the drought-escape response is poorly understood.

Certain Zacks Rank stocks for which no month-end price was available, pricing information was not collected, or for certain other reasons have been excluded from these return calculations. Zacks Ranks stocks can, and often do, change throughout the month. Only Zacks Rank stocks included in Zacks hypothetical portfolios at the beginning of each month are included in the return calculations. The monthly returns are then compounded to arrive at the annual return. A simple, equally-weighted average return of all Zacks Rank stocks is calculated to determine the monthly return. #Srdx transcription plus#Zacks Rank stock-rating system returns are computed monthly based on the beginning of the month and end of the month Zacks Rank stock prices plus any dividends received during that particular month. These returns cover a period from Januthrough August 1, 2022. Since 1988 it has more than doubled the S&P 500 with an average gain of +24.63% per year.

Zacks Style Scores Education - Learn more about the Zacks Style Scores That means you want to buy stocks with a Zacks Rank #1 or #2, Strong Buy or Buy, which also has a Score of an A or a B in your personal trading style. As you might remember from your school days, an A, is better than a B a B is better than a C a C is better than a D and a D is better than an F.Īs an investor, you want to buy stocks with the highest probability of success. Within each Score, stocks are graded into five groups: A, B, C, D and F. There's also a VGM Score ('V' for Value, 'G' for Growth and 'M' for Momentum), which combines the weighted average of the individual style scores into one score. The scores are based on the trading styles of Value, Growth, and Momentum. It allows the user to better focus on the stocks that are the best fit for his or her personal trading style. The Style Scores are a complementary set of indicators to use alongside the Zacks Rank. ![]()
