Table 1 AGO1 plays diverse roles in plant growth, development, and immunity

Arabidopsis

AGO1

AT1G48410

(1) AGO1 positively regulates plant disease resistance to suppressor-defective TCV, BMV, CMV, and S. sclerotiorum

(2) AGO1 negatively regulates plant disease resistance to BaMV, V. dahlia, V. longisporum, B. cinerea, and H. arabidopsidis

AGO1 functions in the determination of plant stature, leaf shape, flower phenotypes, sterility, adventitious rooting, and SAM development in Arabidopsis

(2011), Dzianott et al. (2012), Weiberg et al. (2013), Shen et al. (2014), Cao et al. (2016), Alazem et al. (2017), and Dunker et al. (2020)

Rice (Oryza sativa)

OsAGO1

OsAGO1a: LOC_Os02g45070;

OsAGO1b: LOC_Os04g47870;

OsAGO1c: LOC_Os02g58490;

OsAGO1d: LOC_Os06g51310

OsAGO1 positively regulates plant disease resistance to RDV, RSV, and M. oryzae

OsAGO1 plays a crucial role in rice growth and development

Wu et al. (2009, 2015), Li et al. (2013, 2019b), Wang et al. (2021a), and Shi et al. (2022)

Wheat (Triticum aestivum)

TaAGO1

TaAGO1b

tplb0006m04;

JQ805149

n/d

TaAGO1 is required for the regulation of growth rate, growth features, and adventitious roots

Liu et al. (2011), and Meng et al. (2013)

Nicotiana benthamiana

NbAGO1

NbAGO1-1: DQ321488;

NbAGO1-2: DQ321489;

NbAGO1a: MT701525; NbAGO1b: MT701526.

(1) Loss-of-function of NbAGO1 leads to compromised temperature-dependent symptom recovery of the plants infected with ToRSV

(2) Repressed expression of NbAGO1-1 results in rapidly necrotic symptoms of a Tombusvirus infection.

(3) Both NbAGO1a and NbAGO1b contribute to antiviral defense against tombusvirus

(1) Suppressed expression of NbAGO1 results in developmental defects

(2) NbAGO1b but not NbAGO1a is required for normal development

Tomato (Solanum lycopersicum)

SlAGO1-1; SlAGO1-2

 J×9,945,381;

J×9,945,382

SlAGO1 is sensitive to BWYV P0-mediated destabilization

Reduced expression of SlAGO1 results in pleiotropic morphological defects along with restricted growth at post-germination

Hendelman et al. (2013)

White spruce (Picea glauca (Moench) Voss)

PgAGO

DQ068741

n/d

PgAGO is required for embryo development and is specialized for the proper shoot and root apical meristem differentiation

Tahir et al. (2006)

Foxtail millet (Setaria italica)

SiAGO1b

Seita.7G201100

n/d

SiAGO1b is required for the regulation of growth and development in foxtail millet

Liu et al. (2016)

Malus hupehensis

MhAGO1

MDP0000161046

MhAGO1 negatively regulates plant disease resistance to B. dothidea

n/d
