摘要

为系统鉴定水稻抗旱与耐盐核心基因，对水稻

GATA

家族进行了全基因组鉴定，并探究其胁迫响应特征。结果显示，27个

OsGATA

基因分布于12条染色体，分为6个亚家族（Ⅰ~Ⅵ），其中Ⅳ亚家族成员占比最高（29.6%），且同一亚家族内基因具有保守的基序组成（CX₂CX₁₈

₂₀CX₂C）；跨物种共线性分析显示水稻与玉米（

Zea mays

RefGen_v4）存在18对同源基因，支持单子叶植物

GATA

家族通过祖先基因扩张演化；组织表达谱显示，

OsGATA17

和

OsGATA26

在多数组织中高表达且

OsGATA26

在茎尖分生组织（SAM）中表达尤为显著。qRT-PCR验证表明，干旱胁迫特异性上调

OsGATA5

、

OsGATA8

和

OsGATA13

的表达，而盐胁迫显著抑制

OsGATA18

的表达。上述结果表明，水稻

GATA

家族通过时空特异性表达模式调控非生物胁迫应答，为抗逆基因功能研究提供了重要靶点。

Abstract

Rice，as a staple crop for over half of the global population，faces severe constraints in growth and development due to the drought and salt stress.Mining key regulatory genes for stress resistance in rice and deciphering their molecular mechanisms have become critical strategies for breeding high-yield

and stable-yield varieties with changes in global climate intensifying.A genome-wide identification of the

GATA

transcription factor family was conducted and their characteristics of responding to stress were investigated to systematically identify core drought-resistant and salt-tolerant genes in rice.The results showed that 27

OsGATA

genes were distributed across 12 chromosomes of rice and classified into 6 subfamilies （I-VI），with subfamily IV accounting for the highest proportion（29.6%）.Members within the same subfamily exhibited conserved motif compositions （CX₂CX₁₈

₂₀CX₂C）.The results of cross-species collinearity analysis showed that there were 18 homologous gene pairs between rice and maize （

Zea mays

RefGen_v4），indicating that the evolutionary expansion of the

GATA

family in monocots is through ancestral gene duplication.The results of tissue-specific expression profiles showed that

OsGATA17

and

OsGATA26

are highly expressed in most tissues，with the expression of latter displaying particularly prominent in the shoot apical meristem （SAM）.The results of qRT-PCR validation showed that

OsGATA5

，

OsGATA8

，and

OsGATA13

were specifically upregulated under the drought stress，while

OsGATA18

was significantly suppressed under the salt stress.It is indicated that the rice

GATA

family regulates the responses to abiotic stress with spatiotemporal-specific patterns of gene expression.It will provide critical targets for studying the functions of stress-resistance genes.
